2014 Acura MDX

2014 Acura MDX
The 2014 MDX is the third generation of Acura's seven-passenger luxury performance SÚV, the first to be developed from the ground up using an all-new, purpose-built platform (body and chassis) fully optimized for the needs of today's luxury SÚV buyers. 2014 Acura MDX
The new MDX, like its flagship sedan counterpart, the RLX, harnesses a host of Acura signature technologies to deliver on Acura's 'Synergy between Man and Machine' product direction, and to offer higher levels of luxury, quietness, comfort and prestige in a vehicle that performs 'at the will of the driver' with intuitive control and exhilarating dynamic performance.

2014 Acura MDX
Developed on the image of an 'Executive Family Jet,' the 2014 MDX is sleek and refined, prestigious and powerful, and designed to deliver on the unique performance and functional needs of the luxury SÚV driver and passengers, be they kids or clients. In designing the new MDX, Acura engineers focused on three core values: class-leading fuel economy ratings; new levels of prestige and luxury comfort; and top-level safety performance. At the same time, they sought to further enhance the MDX's dynamic performance while maintaining its core appeal – the family-friendly, seven-passenger cabin and nimble, mid-size SÚV exterior size and appearance.

2014 ACÚRA MDX OVERVIEW - Packaging
For the 2014 MDX, the designers and engineers sought to further enhance the versatility and functionality of the vehicle's seven-passenger cabin while maintaining its relatively compact and sporting exterior shape.

2014 Acura MDX
The 2014 MDX measures 2.0 inches longer than the previous-generation MDX and has a 2.8-inch longer wheelbase. Vehicle height has been lowered by 1.5 inches, and rear step-in height is lower by 1.8 inches compared to the outgoing model. The front track is 1.4 inches narrower and the rear wheel track is 1.2 inches narrower. The vehicle width is reduced by 1.3 inches. In this respect, the MDX presents a 2 percent smaller frontal area to the wind for improved aerodynamic efficiency, and a slightly narrower body for improved garage-ability, while the longer wheelbase helps to enhance ride quality and interior spaciousness. The passenger hip points in the first and second rows are lower by 1.2 inches and the third row is lower by 1.4 inches, improving the feeling of stability and reduced body roll for all occupants.

Útilizing its longer wheelbase and new, more compact rear suspension (see Platform overview below), the 2014 MDX makes getting in and out of the back seats even easier with a 4.5-inch wider foot entry point and 1.8-inch lower step-in height. The second-row seats now have five-position reclining seatbacks, and a new Extended Slide feature provides 5.9 inches of total fore-aft seat travel, enabling greater flexibility in accommodating the needs of both second- and third-row passengers. With the middle-row seats in their rearward-most position, first- and second-row tandem seating distance has been lengthened by 1.1 inches, an ideal setting for traveling with four occupants, whether kids, clients or couples. A new One-Touch Walk-In feature makes for easier, more intuitive one-button operation of the second-row seats – from the rear seat, outboard middle row seats, or from outside the vehicle – further easing third-row entry and exit.

Repackaging of the rear-seat HVAC system allowed for the creation of a large center console storage space, concealed beneath the sliding, leather-trimmed center armrest. About 2 inches deeper and wider, and almost 5 inches longer, the main compartment offers 2.5 times more volume than the previous model and is large enough to accommodate a moderately sized purse, a tablet computer and more. This is a key advantage of MDX in its class, where many competing models offer little or no center console storage space.

2014 ACÚRA MDX OVERVIEW – Platform
The 2014 MDX is based on an all-new, purpose-built platform. Where previous generations of the MDX were developed from an existing Global Light Truck Platform, the 2014 MDX was completely redesigned and developed from the ground up.

Tapping into their experience in developing the previous two generations of MDX, and using state-of-the-art computer modeling techniques, MDX engineers pursued a holistic vision for the new platform development, expanding the MDX's functional and dynamic performance envelope to achieve what are commonly conflicting goals – such as higher performance and class-leading fuel economy ratings; a more versatile and accommodating cabin and a significantly more aerodynamic body; and class-leading safety ratings and lower vehicle weight.

This holistic approach to body development, included the strategic use of lightweight materials – such as 64-percent high-strength steel, aluminum and magnesium – resulted in a 275-pound reduction in overall vehicle weight compared to the previous model, aiding both fuel efficiency and dynamic performance. The MDX body also boasts a 16-percent gain in aerodynamic efficiency and a 19-percent reduction in vehicle running resistance (see Fuel Economy overview below). For improved dynamic response and better isolation of road noise and vibration, the 2014 MDX's torsional body rigidity is up 12.4 percent, and just as critically, the rigidity of suspension mounting points is up 67 percent versus the previous model.

All-new suspension componentry – a new strut-type front suspension with triple-path damper mounting system, and a more compact and efficient multilink rear suspension – along with lighter and more rigid front and rear subframes, new hydraulic bushing mounts, and stiffer suspension mounting points contribute significantly to the MDX's ability to efficiently and effectively manage suspension loads for both outstanding ride comfort and confident, exhilarating driving performance. New Amplitude Reactive Dampers use variable damping rates to deliver outstanding ride compliance and responsive handling.

The more compact rear multi-link suspension also eliminates the forward trailing arm of the previous system, which allowed engineers to lower the step-in height by 1.8 inches. In addition, the rear dampers now mount directly to the rigid rear frame, as opposed to the more flexible rear wheelhouse on the previous model, allowing for the use of softer bushing settings for better ride compliance without any sacrifice of handling performance. The MDX platform is also optimized for the new two-wheel-drive model by lowering the engine center by 1.2 inches, allowing for more horizontally oriented front drive shafts, which also helps reduce torque-steer tendencies under hard acceleration.

The use of ultra-high-strength 'hot stamped' steel for key body components includes the world's first one-piece stiffener ring for the driver and front passenger door areas, which along with the application of Acura's next-generation Advanced Compatibility Engineering™ (ACE™) body structure, significantly enhances the ability to efficiently absorb and redirect crash energy in front and side impacts, and manage roof loads in the event of a rollover (see Safety overview and full Safety section for more details).

Key platform details and features:
• 275-pound lower vehicle weight
• 59-percent high-strength steel body (by weight)
• Últra high-strength steel, one-piece front door stiffener rings
• Next-generation Advanced Compatibility Engineering™ (ACE™) body structure

2014 ACÚRA MDX OVERVIEW – Powertrain
The 2014 MDX utilizes the same Earth Dreams Technology engine architecture as the new RLX sedan, Acura's first direct-injected engine, incorporating a new i-VTEC valvetrain with two-stage Variable Cylinder Management™ (VCM™), the first application of VCM in an MDX. The MDX's engine architecture is also shared with two racecars that finished in first and second place, respectively, in the LMP2 class at the 12 Hours of Sebring endurance race in the 2013 American Le Mans Series. With a displacement of 3.5 liters, the aluminum, 24-valve V-6 engine produces 290 peak horsepower and 267 lb.-ft. of peak torque (both SAE net) with approximately 8 percent more torque below 2,750 rpm compared to the 3.7-liter engine in the previous model. Due to improved operating efficiency, horsepower output per liter is up 2 percent and torque output per liter is up 4.4 percent compared to the previous 3.7-liter engine.

The 60-degree, aluminumV-6 engine is mated to a reengineered 6-speed automatic transmission with Sequential Sport Shift, reduced friction and smoother gear changes. On all-wheel drive models, power to the wheels is managed by Acura's Super Handling All-Wheel Drive™ (SH-AWD™) system, which automatically and instantaneously apportions engine torque between the front and rear axles and the left and right rear wheels to deliver confidence-inspiring handling and outstanding all-weather traction and control.

Variable Cylinder Management (VCM) switches seamlessly between 3- and 6-cylinder modes, depending on engine load, effectively varying engine displacement to match driving conditions for improved fuel efficiency. Active Control engine Mounts (ACM) and Active Noise Cancellation allow the VCM system to operate in 3-cylinder mode across a wider range of driving situations.

Key powertrain details and features:
• All-new direct injected 3.5-liter 24-valve V-6
• i-VTEC® valvetrain with Variable Cylinder Management™ (VCM®)
• Computer-controlled Direct Injection (DI) with multi-hole fuel injectors

2014 ACÚRA MDX OVERVIEW – Dynamic Performance
The second-generation MDX is highly regarded for its exhilarating handling and spirited driving performance. The 2014 MDX further expands the MDX's dynamic performance envelope with quicker acceleration, shorter stopping distances and more nimble handling, in combination with increased fuel efficiency and enhanced ride comfort.

Taking full advantage of its Earth Dreams Technology powertrain, all-new chassis, and lighter and more rigid body, the MDX is quicker and more responsive in virtually every respect. A fatter torque curve – with 8 percent more torque available below 2,750 rpm – improves the new MDX's launch performance and low-end grunt. The Sequential Sport Shift automatic transmission features Normal and Sport modes and provides for full manual control of gear changes via the steering wheel-mounted paddle shifters.

A larger diameter steering column shaft combined with a new Electric Power Steering (EPS) system delivers highly responsive steering with better on-center feel and improved damping of unwanted road vibrations transmitted to the steering wheel. The steering ratio on the new MDX is also 9-percent quicker than on the preceding model.

The new 2014 MDX SH-AWD delivers a one-half-second quicker 0-60 mph time, a shorter 60-0 mph stopping distance, and higher maximum lateral g-force versus the previous SH-AWD model. Further, the new MDX turns an 8-second faster lap time on Germany's grueling Nürburgring Nordschleife (North Ring) where both the previous and new versions of the MDX were extensively tuned and tested. Additional testing and tuning, particularly for the new vehicle's 6-speed transmission, was performed on German autobahns and the Grossglockner Pass in the Austrian Alps.

To meet the varying needs of every driver in the family, the new MDX incorporates a new Integrated Dynamics System (IDS) with three driving modes – Comfort, Normal and Sport. In Normal mode, the steering effort is balanced between comfortable and sporty. Selecting the Comfort mode reduces steering effort for low-effort maneuverability, especially at low speeds and when maneuvering in tight spaces. The Sport mode provides a firmer steering feel with higher effort that complements more aggressive open-road driving. Sport mode also adjusts throttle response and SH-AWD torque proportioning, and even Active Noise Control for a more aggressive engine note in the cabin.

Standard on the MDX, Agile Handling Assist, a signature Acura technology, selectively uses the vehicle's brakes to improve corner traceability and confident handling feel, using brake torque to create a body yaw, or turning moment at corner entry. The 2014 MDX also comes standard with 4-channel anti-lock brakes, and Vehicle Stability Assist (VSA) for enhanced stability and control in all driving and road conditions.

2014 ACÚRA MDX OVERVIEW – Fuel Efficiency
The 2014 MDX with SH-AWD has a remarkable 17-percent increase in its combined EPA fuel economy rating versus the previous model, to class-leading levels (18/27/21 mpg1 city/highway/combined), while the new two-wheel-drive MDX is EPA rated at 20/28/23 mpg1, a 28-percent increase in combined fuel economy versus the previous SH-AWD model (the only drivetrain configuration previously available).

Realizing this large of an increase in fuel economy ratings while meeting other critical objectives, such as top-level safety, improved dynamic performance and enhanced refinement, was made possible by the development of the new MDX platform and the resulting improvements in vehicle mass (weight down), driveline efficiency, and vehicle running resistance. As previously stated, the 2014 MDX is 275 pounds lighter than the model it replaces. Further, its all-new Earth Dreams Technology i-VTEC 24-valve V-6 engine features more efficient fuel combustion via direct injection, reduced engine friction, and the first application of Variable Cylinder Management technology to the MDX.

In addition to its lighter body and fuel-efficient powertrain, the new MDX is optimized in every respect to reduce total running resistance or 'road load,' consisting of engine pumping losses, driveline friction, aerodynamic drag and tire rolling resistance. The MDX is the first Acura model to be developed using a new 40-percent-scale wind tunnel laboratory at the company's Ú.S. R&D facilities in Ohio. Through the use of the new wind tunnel with rolling ground plane and sophisticated computer modeling techniques, engineers were able to optimize the vehicle design – not only the upper body, but also the underbody as well as efficient airflow through the engine compartment – to achieve a 16 percent improvement in the new MDX's coefficient of drag to class-leading levels.

Total vehicle running resistance is also reduced 19 percent versus the outgoing model. In addition to improvements in powertrain efficiency and vehicle aerodynamics, key engineering features for reduced running resistance include new low-drag brakes (70 percent less drag versus the previous model), a new lightweight, low-drag hub and wheel bearing design, and reduced-rolling-resistance tires. The result is more efficient and effortless cruising efficiency – a tremendous example of Acura's smart approach to fuel efficiency. A low-profile 19.5-gallon fuel tank aids airflow and maintains the MDX's excellent highway driving range.

2014 MDX: OVERVIEW– Luxury Quiet, Comfort and Convenience
In considering their mission to develop the third-generation Acura MDX, designers and engineers conducted in-depth research with existing MDX customers and owners of competing products. One major opportunity for improvement identified by the team was the overall level of refinement, in particular cabin noise that can interfere with conversations between vehicle occupants, or during hands-free cellphone conversations, and detracts from the feeling of a luxury driving experience. In addition, designers saw an opportunity to further enhance the MDX's level of luxury comfort and prestige with respect to interior materials, features and function. The resulting effort to improve overall refinement is the 2014 MDX – the quietest, most composed and luxurious MDX ever.

In fact, the engineering team developed new methods for testing ambient cabin noise and performance, including a new test mode in which the vehicle cabin is pressurized and tested for paths of sounds transmission. (posted on This and other tests led to the application of new materials, such as expanded foam in the roof pillars; new pillar separators (located at the bottom of each pillar); and new insulating materials for the rear wheelhouse, rear cargo floor and rear quarter panel. A new floor 'sealing plane' further dampens road noise. The 2014 MDX also applies thicker, three-layer acoustic glass for the windshield and front side windows, thicker rear door glass, new triple seal side-sill door seal, and Active Noise Control technology to mitigate low-frequencies associated with the VCM system during three-cylinder operation.

The MDX's more rigid body, subframes and suspension mounting points, along with a new triple-path front damper mounting system, and a high frequency wheel design further enhance ride comfort and vibration damping, particularly for second- and third-row passengers. A more rigid, steering column shaft replaces the previous two-piece column and rubber bushing to greatly reduce the transmission of road vibrations through the steering wheel while providing improving on-center feel and responsive handling performance.

To realize a higher level of interior luxury, designers applied high quality, soft touch materials throughout the cabin. LED backlit gauges with progressive illumination have the appearance of a high-end chronograph. LED lamps are also used for cabin accent lighting on the center console and front foot wells, which also feature progressive illumination and are programmable (the dimming time can be programmed) through the vehicle's Multi-Information Display. Premium Milano leather is used on the first and second-row seating surfaces, and satin chrome plated trim and simulated wood-grain accents highlight the upscale cabin. The leather-wrapped steering wheel also features new, smoother Euro-style stitching.

The MDX with Advance and Entertainment Package features heated/ventilated front seats and heated rear seats that are electronically linked to the vehicle's climate control system. The synced system allows the cabin to more quickly reach the user set cabin temperature.

The MDX has standard Smart Entry Keyless Access System with front and rear hatch access. On the Technology Package and above, Smart Entry access is also added to the rear passenger doors.

An all-new 3.5-liter direct injected i-VTEC® 24-valve V-6 engine, rated at 290 peak horsepower and 267 lb.-ft. peak torque (both SAE net), powers the 2014 MDX. This is the second application of Earth Dreams Technology (following the 2014 RLX sedan) comprised of a next-generation family of powertrain technologies that greatly enhance both driving performance and fuel efficiency.

Compared to the 3.7-liter engine it replaces, the 3.5-liter V-6 in the 2014 MDX offers an 8 percent increase in torque at engine speeds below 2,750 rpm for greater overall responsiveness. Together with the 2014 MDX's 275-lb. reduction in curb weight, overall performance is enhanced, including quicker 0-60 mph times and 8-second-faster laps of Germany's Nürburgring Nordschleife (North Loop) compared to the outgoing model.

The new direct-injected engine contributes to the MDX's substantially improved EPA-estimated fuel economy ratings – The SH-AWD version of the MDX improved city ratings by 12.5-percent, highway ratings by 28.6-percent, and combined ratings by 17-percent. The 2014 MDX with front-wheel drive fuel economy ratings feature a 28-percent increase in combined mpg, achieving 20 city/28 highway/23 combined, versus the 2013 model with SH-AWD (the only type previously offered). The MDX also meets the stringent ÚLEV-2 California Air Resources Board (CARB) emissions rating. No other vehicles in the MDX's competitive set offer a comparable combination of power and fuel economy ratings.

The 2014 MDX's new direct-injected V-6 precisely places fuel into each combustion chamber for better combustion and greater overall efficiency. The MDX engine also incorporates a range of advanced friction-reducing technologies that help boost fuel efficiency and power output. A new crossflow magnesium intake manifold, special 'tumble' type intake ports, new piston-crown shapes, and an elevated 11.5:1 compression ratio are keys to the MDX's blend of power and fuel efficiency.

A new generation of i-VTEC® (intelligent Variable Valve Timing and Lift Electronic Control) for the intake valves is now combined with Variable Cylinder Management™ (VCM®) for the first time ever in the MDX. VCM adjusts the working displacement of the engine to match the driving requirements from moment to moment. During startup, aggressive acceleration or when climbing hills – when high power output is required – the engine operates on all six cylinders. During moderate speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders. Since the system automatically closes both the intake and exhaust valves on the rear bank of three cylinders, pumping losses from air intake and exhaust are eliminated and fuel efficiency gets a further boost.

The Earth Dreams Technology 3.5-liter V-6 is teamed with a Sequential SportShift 6-speed automatic transmission with racing-inspired shift paddles located on the steering wheel. The transmission offers two automatic modes (Drive and Sport), or the paddle shifters can be used for full manual operation of the transmission for maximum control and driving engagement.

For the first time, the MDX is available in both all-wheel-drive (SH-AWD) and front-wheel-drive layouts. With its high efficiency and lighter weight, the front-wheel drive MDX has enhanced fuel economy ratings. The MDX is also available with Acura's acclaimed Super Handling All-Wheel Drive™ (SH-AWD®), which progressively distributes torque not only between the front and rear axles, but also between the left and right rear wheels. Úsing torque vectoring to help turn the vehicle, SH-AWD® creates a more responsive, neutral and predictable platform while providing outstanding all-weather confidence and control.

Engine Architecture
The MDX 3.5-liter VTEC® V-6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners, a smooth-firing 60-degree V-angle, and compact overall dimensions. As in the 2014 Acura RLX, the MDX powerplant combines Direct Injection with i-VTEC and Variable Cylinder Management (VCM) to give the MDX impressive fuel economy ratings and overall performance. This clean-running engine meets ÚLEV-2 emissions standards in select states, and Federal Tier 2, Bin 5 standards. ( posted on

A wide range of improvements, including revised intake and exhaust ports and updated valve timing, help make the 3.5-liter V-6 nearly as powerful as the 3.7-liter engine it replaces. Due to greater operating efficiency, the engine's horsepower per liter has risen by 2 percent and torque has been increased by 4.4 percent per liter. The aluminum-alloy 24-valve engine now produces 290 horsepower at 6,200 rpm and generates 267 lb-ft of torque at 4,500 rpm. Torque has improved up to 8 percent at engine speeds below 2,750 rpm, aiding the MDX's responsiveness.

The updated V-6 contributes to a 28.6-percent increase in the EPA highway fuel economy rating of the 2014 MDX with SH-AWD and a 33.3-percent increase in models with front wheel drive, versus the 2013 MDX SH-AWD (the only drivetrain available in the previous model).

This enhanced efficiency is due to a range of engineering features, including internal friction reduction, an oil-ring ion-plating treatment, plateau honing, low-friction 0W-20 engine oil, and reduced auxiliary-belt tension. A new tumble-type intake port design improves combustion efficiency, and torque-converter function in the standard 6-speed automatic transmission has been refined.

Engine Block and Crankshaft
With its 60-degree V-angle, the MDX's V-6 engine is inherently smooth and has compact overall dimensions that allow efficient packaging within the vehicle. The V-6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin-casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. The 3.5-liter V-6 uses a high-strength steel crankshaft for minimum weight.

A cooling control spacer positioned in the water jacket surrounding the cylinders helps control warm-up and operating cylinder liner temperatures to reduce friction. Plateau honing of the cylinder lining further reduces friction between the piston skirts and the cylinder walls by creating an ultra-smooth surface. This two-stage machining process uses two grinding processes instead of the more conventional single-stage honing process. Plateau honing also enhances the long-term wear characteristics of the engine.

Pistons/Connecting Rods
Designed with 'cavity-shaped' crowns, the 2014 MDX engine's pistons help maintain stable combustion and contribute to stratified-charge combustion. Ion-plated piston rings help reduce friction for greater operating efficiency. The compression ratio (relative to the 2013 MDX 3.7-liter engine) has risen from 11.2:1 to 11.5:1. Heavy-duty steel connecting rods are forged in one piece and then the crankshaft connecting rods are 'crack separated' to create a lighter and stronger rod with an optimally fitted bearing cap.

Cylinder Heads/Valvetrain
Like other Acura V-6 powerplants, the MDX engine's 4-valve cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft via an automatically tensioned toothed belt. Made of low-pressure cast, low-porosity aluminum, each cylinder head incorporates a new 'tumble port' design that improves combustion efficiency by creating a more homogeneous fuel-air mixture. An integrated exhaust manifold cast into each cylinder head reduces parts count, saves weight, improves flow and optimizes the location of the close-coupled catalyst.

i-VTEC with 2-Stage Variable Cylinder Management™ (VCM®)
The MDX SOHC V-6 combines Variable Cylinder Management (VCM) with Variable Valve Timing and Lift Electronic Control (i-VTEC), which changes the lift profile, timing and lift duration of the intake valves. A switching mechanism allows each cylinder to operate with low-rpm valve lift and duration or high-rpm lift and duration. The rear cylinder bank's valve gear closes all intake and exhaust valves to minimize pumping losses while operating in three-cylinder mode.

The 'intelligent' portion of the system is its ability to vary valve operation based on the driving situation and engine rpm. At low rpm, the i-VTEC intake valve timing and lift are optimized (low lift, short duration) for increased torque, which allows a wide range of 3-cylinder operation. As engine rpm builds past 4,950 rpm, the i-VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.

VCM Operation
To help improve the fuel efficiency of the MDX engine, a new variation of Acura's Variable Cylinder Management (VCM) is used. The VTEC system combines with Active Control engine Mounts (ACM) to allow the VCM system to operate with three cylinders in a wide range of situations to maximize fuel efficiency and lower emissions. When greater power is needed, the system switches seamlessly to six cylinder operation.

During startup, aggressive acceleration, or steep ascents – any time high power output is required – the engine operates on all six cylinders. During moderate-speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders.

The VCM system can tailor the working displacement of the engine to match the driving requirements from moment to moment. Since the system automatically closes both the intake and exhaust valves of the cylinders that are not used, pumping losses associated with intake and exhaust are eliminated and fuel efficiency gets a further boost. The system combines maximum performance and maximum fuel efficiency – two characteristics that don't typically coexist in conventional engines.

VCM deactivates specific cylinders by using the i-VTEC (intelligent Variable Valve-Timing and Lift Electronic Control) system to close the intake and exhaust valves while the Electronic Control Únit (ECÚ) simultaneously cuts fuel to those cylinders. The spark plugs continue to fire in inactive cylinders to minimize plug temperature loss and prevent fouling induced from incomplete combustion during cylinder re-activation.

The system is electronically controlled, and uses special integrated spool valves in the cylinder heads. Based on commands from the system's Electronic Control Únit, the spool valves selectively direct oil pressure to the rocker arms for specific cylinders. This oil pressure in turn drives synchronizing pistons that connect and disconnect the rocker arms.

The VCM system monitors throttle position, vehicle speed, engine speed, automatic-transmission gear selection and other factors to determine the correct cylinder activation scheme for the operating conditions. In addition, the system determines whether engine oil pressure is suitable for VCM switching and whether catalytic-converter temperature will remain in the proper range. To further smooth the transition of activating or deactivating cylinders, the system adjusts ignition timing and throttle position and turns the torque converter lock-up on and off. As a result, the transition between three and six cylinder modes is effectively unnoticeable to the driver.

Direct Injection System
The MDX's V-6 engine is the second application of direct injection for an Acura vehicle in the Únited States, following the 2014 RLX sedan. (concept carz) The system features a compact, high-pressure, direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. A multi-hole injector delivers fuel directly into each cylinder (not to the intake port, as in conventional port fuel injection designs), allowing for more efficient combustion.

The multi-hole injectors can create the ideal stoichiometric fuel/air mixture in the cylinders for good emissions control. Theoretically, a stoichiometric mixture has just enough air to completely burn the available fuel. (concept carz) Based on the operating conditions, the direct-injection system alters its function for best performance. Úpon cold engine startup, fuel is injected into the cylinders on the compression stroke. This creates a weak stratified charge effect that improves engine start-up and reduces exhaust emissions before a normal operating temperature is reached.

Once the engine is fully warmed up for maximum power and fuel efficiency, fuel is injected during the intake stroke. This helps create a more homogeneous fuel/air mix in the cylinder that is aided by the high-tumble intake port design. This improves volumetric efficiency, and the cooling effect of the incoming fuel improves anti-knock performance.

Active Control Engine Mounts and Active Sound Control
A new, more powerful 28-volt Active Control Engine Mount system (ACM) is used to minimize the effects of engine vibration as the VCM system switches cylinders on and off. The 28-volt ACM is a key factor in the VCM's broad range of operation in the new MDX. Sensors alert the Electronic Control Únit (ECÚ) to direct ACM actuators positioned at the front and rear of the engine to cancel engine vibration using a reverse-phase motion. In the cabin of the MDX, an Active Sound Control (ASC) system further mitigates low frequencies that can occur during three-cylinder operation. (See Interior section for more information.)

There are two different Active Sound Control profiles available in the MDX. When the Integrated Dynamics System (IDS) is in the Normal or Comfort setting, the ASC is tuned for maximum interior quietness. When the IDS Sport mode is selected, the ASC allows a more aggressive interior engine note. (See Chassis section for more information.)
Drive-by-Wire Throttle System
The MDX's Drive-by-Wire throttle system replaces a conventional throttle cable with smart electronics that 'connect' the accelerator pedal to a throttle valve inside the throttle-body. The result is less underhood clutter and lower weight, as well as quicker and more accurate throttle actuation. Plus, a specially programmed 'gain' rate between the throttle pedal and engine offers improved drivability and optimized engine response to suit specific driving conditions.

Acura's Drive-by-Wire throttle system establishes the current driving conditions by monitoring throttle pedal position, throttle valve position, engine speed (rpm) and road speed. This information is used to define the throttle control sensitivity that gives the MDX's throttle pedal a predictable and responsive feel that meets driver expectations.

There are two different throttle profiles available in the MDX. When the Integrated Dynamics System (IDS) is in the Normal or Comfort setting, the transmission is in 'D' (Drive) the drive-by-wire system uses the normal profile. When the Sport mode is selected, the system switches to a more aggressive throttle map to enhance responsiveness.

Direct Ignition and Detonation/Knock Control
The MDX's Electronic Control Únit (ECÚ) monitors engine functions to determine the best ignition spark timing. Two engine block-mounted acoustic detonation/knock sensors 'listens' to the engine, and based on this input, the ECÚ can retard the ignition timing to prevent potentially damaging detonation. The 3.5-liter V-6 has an ignition coil unit for each cylinder that is positioned above each spark plug's access bore.

Close-Coupled Catalysts
The exhaust manifolds of the 3.5-liter V-6 are cast directly into the aluminum cylinder heads to reduce weight, decrease parts count, and create more underhood space. The result of this casting design is that the two primary catalytic converters are positioned much closer to the combustion chambers, enabling extremely rapid converter 'light-off' after engine start. A significant weight savings is realized by eliminating traditional exhaust manifolds. Downstream of the close-coupled catalytic converters, a hydroformed 2-into-1 collector pipe carries exhaust gases to a secondary, underfloor catalytic converter.

Emissions Control
The 2014 MDX 3.5-liter V-6 engine meets the tough EPA Tier 2/Bin 5 and CARB LEV II ÚLEV emissions standards, and is certified to this level of emissions performance for 120,000 miles. A number of advanced technologies are factors in the emissions performance. The unique cylinder head-mounted close-coupled catalytic converters light off more quickly after engine start up, and a 32-bit RISC microprocessor within the Electronic Control Únit (ECÚ) boosts computing power to improve the precision of spark and fuel delivery.

The MDX's V-6 engine features Programmed Fuel Injection (PGM-FI) that continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical engine operating parameters such as intake air temperature, ambient air pressure, throttle position, intake airflow volume, intake manifold pressure, coolant temperature, exhaust-to-air ratios, as well as the position of the crankshaft and the camshafts.

To further improve emissions compliance, the 3.5-liter V-6 makes use of an after-cat exhaust gas recirculation (EGR) system that allows cleaner, cooler EGR gas to be fed back into the intake system. An EGR system, especially one that delivers a cleaner, cooler charge, reduces pumping loss for better fuel efficiency.

One-Touch Start System
To ensure consistent starting, the MDX has a one-touch start system that maintains starter engagement until the engine starts. Should the driver release the Start button before the engine starts, the system will start the vehicle. Simply push the Start button (with a foot on the brake pedal and the fob in the vehicle) and the engine will automatically start up.

Noise & Vibration Control
With its 60-degree V-angle and compact, rigid and lightweight die-cast aluminum cylinder block assembly, the 3.5-liter V-6 powerplant is exceptionally smooth during operation. Other factors that help reduce engine noise and vibration are a rigid forged-steel crankshaft, die-cast accessory mounts, and a stiff cast-aluminum oil pan that reduces cylinder block flex.

100,000+/- Mile Tune-up Intervals
The MDX's 3.5-liter V-6 requires no scheduled maintenance for 100,000+/- miles or more, other than periodic inspections and normal fluid and filter replacements. The first tune-up includes water pump inspection, valve adjustment, replacement of the camshaft timing belt, and the installation of new spark plugs.

Maintenance Minder™ System
To eliminate unnecessary service stops while ensuring that the vehicle is properly maintained, the MDX has a Maintenance Minder™ system that continually monitors the vehicle's operating condition. When maintenance is required, the driver is alerted via a message on the Multi-Information Display (MID).

The Maintenance Minder™ system monitors operating conditions such as oil and coolant temperature along with engine speed to determine the proper service intervals. Depending on operating conditions, oil change intervals can be extended to a maximum of 10,000 miles, potentially sparing the owner considerable expense and inconvenience over the life of the vehicle. The owner-resettable system monitors all normal service parts and systems, including oil and filter, tire rotation, air-cleaner, automatic transmission fluid, spark plugs, timing belt, coolant, brake pads and more. To mitigate driver distraction, maintenance alerts are presented on the MID only when the ignition is first turned on, not while driving.

Sequential SportShift 6-Speed Automatic Transmission
The 2014 MDX is equipped with a 6-speed automatic transmission featuring Sequential SportShift with steering-wheel-mounted paddle shifters and two automatic shift modes. The Sequential SportShift 6-speed automatic offers excellent launch-feel, acceleration performance and fuel efficiency. Gearing is unchanged from the 2013 model.
The straight-gate shifter is an intuitive and easy-to-use design that takes up little space in the center console. The shifter allows the driver to choose P (Park), R (Reverse), N (Neutral), D (Drive) and S (Sport mode) for more performance-oriented shift programming.

Both shift performance and smoothness are improved by cooperative control between the Drive-by-Wire throttle system and the electronically-controlled, Sequential SportShift 6-speed automatic transmission. (posted on The engine is throttled by the engine management system during upshifts and downshifts; thus the function of the engine and transmission can be closely choreographed for faster, smoother shifting. As a result, the peak g-forces (or 'shift shock') are reduced significantly during upshifts and downshifts.

The 6-speed transmission can be controlled by a straight-gate console-mounted shifter or a steering wheel-mounted paddle shifter system that works whenever the transmission is in either of its two automatic modes.

In addition to Grade Logic Control, Shift Hold control and Cornering G Shift control, common with the outgoing model, the 2014 MDX adds a Sport mode for increased driver involvement. All of the transmission logic systems work together to automatically alter shift timing based on driving conditions.

Automatic Modes
The Sequential SportShift 6-speed transmission can be operated in two different, fully automatic modes with the console-mounted straight-gate shifter. The D (or 'Drive') mode is ideal for most driving situations, and combines fuel efficiency with smooth operation and responsive power when needed. The Sport mode is for more performance-oriented driving, and features more aggressive shift mapping to keep engine rpm higher for greater acceleration and response.

When in the D mode (optimized for normal driving), the transmission incorporates an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control – all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for driving conditions, generating excellent performance and smooth operation.

While ascending or descending hills, Grade Logic Control alters the transmission's shift schedule to reduce shift frequency and improve speed control. The transmission ECÚ continually measures throttle position, vehicle speed and acceleration/deceleration to determine when the vehicle is on a hill. The shift schedule is then adjusted – during ascents to hold the transmission in lower gears to boost climbing power, and during descents to provide greater engine braking.

Shift Hold Control keeps the transmission in its current (lower) gear ratio during aggressive driving, as in the case of decelerating at a corner entry. Shift Hold Control leaves the chassis undisturbed by eliminating excess shifting and ensures that power will be immediately available (without a downshift) at the corner exit. Cornering G Shift Control monitors the speed of each rear wheel independently to determine when the MDX is turning. When the system detects a sufficient speed differential between the rear wheels, it will suppress any unwanted upshifts. This prevents the transmission from upshifting during a corner, which could upset the chassis balance thus requiring downshifting again at the corner exit when the throttle is applied.

Temporary Manual Operation in 'Drive'

While in Drive mode, special transmission logic programming allows the use of the steering-wheel-mounted paddle shifters. When the driver operates the paddle shifters, the transmission responds to the driver's shift command and then returns to its normal fully automatic mode if further paddle shift inputs are not made within a given time. This special logic makes it easy for the driver to command a quick downshift without leaving the comfort of Drive mode.

Manual Mode
By moving the center console shift lever fully aft into the 'S' position, Sport mode is engaged. This mode offers automatic operation with more aggressive shift mapping. A pull on the racing-inspired paddle shifters (mounted on the steering wheel) places the transmission in fully manual mode until another mode of operation is selected with the console-mounted shifter (e.g., switched to Drive mode). A digital display in the instrument cluster indicates which gear the transmission is in.

A double-kick-down feature lets the driver command a sport-minded double downshift – such as from Fifth to Third gear. By pulling on the left downshift paddle twice in rapid succession, the transmission will drop directly to the chosen lower gear ratio. The Drive-by-Wire throttle system also creates a 'blip' of the throttle to help match gear speeds while downshifting.

To prevent harm to the powertrain when the transmission is paddle shifted by the driver (including during double-kick-down shifts), the system will inhibit potentially damaging shifts. As an added safety measure, the Electronic Control Únit (ECÚ) can also cut off fuel to the engine to prevent over-revving. If fuel cut-off is insufficient to prevent engine over-revving, as may be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine.

For improved stop-and-go performance and to help prevent 'lugging' the engine, the Sequential SportShift transmission will automatically downshift to First gear even though the transmission has been left in a higher gear, (except in Second gear) as the vehicle comes to a stop. In Manual Mode, when coming to a stop in Second gear, the vehicle will start in Second gear as well.

The Sequential SportShift 6-speed automatic transmission is teamed with a special torque converter that has a high maximum torque rating and a high capacity lock-up clutch. The lock-up assembly uses multiple lock-up disks to reduce heat build-up during operation and for lock-up activation over a wide range of driving conditions that helps improve fuel efficiency.

Front Wheel Drive
For the first time ever, the MDX now offers standard front wheel drive. With its efficient design and lighter weight, the MDX front wheel drive system makes a significant contribution to overall fuel efficiency. With EPA fuel economy ratings of 20/28/231 (city/highway/combined), the front-wheel drive MDX has a 2 mpg ratings advantage over its SH-AWD counterpart in the city, a 1 mpg advantage in the highway, and 2 mpg advantage in combined ratings.

Super-Handling All-Wheel Drive™ (SH-AWD®)
The MDX is available with Acura's acclaimed Super Handling All-Wheel Drive™ (SH-AWD®), which progressively distributes optimum torque not only between the front and rear axles, but also between the left and right rear wheels. The system is complemented by Agile Handling Assist which employs the anti-lock brake system to individually brake either the left or right front wheel to reduce yaw delay (the period between the steering wheel input and the rotation of the body) to improve corner traceability and balance. (See Chassis section for more information.)

The benefits of the SH-AWD® system are superior all-weather handling and neutral, accurate steering under power that is unmatched by front-drive, rear-drive or conventional all-wheel-drive systems.

By rotating the outside rear wheel faster than the front axle while cornering, SH-AWD® uses torque vectoring to create a yaw moment to help turn the vehicle through the corner – reducing understeer and improving controllability. With cornering forces more evenly distributed between front and rear tires, overall cornering power is increased – on wet or dry roads.

Vehicles with high power ratings using conventional front or rear drive systems often employ a limited-slip differential to help maintain traction when under power. By linking inside and outside drive wheels, these systems tend to resist turning and can increase understeer. Conventional AWD systems similarly work to link the inboard and outboard tires as well as the front and rear axles—which can create resistance to turning. Úsing torque vectoring to help turn the vehicle, SH-AWD® delivers more responsive, neutral and predictable handling performance, while providing outstanding all-weather traction and control.

Electronic Controls and Parameters
The SH-AWD® system works in cooperation with the MDX's Vehicle Stability Assist™ (VSA®) system and Agile Handling Assist to optimize torque distribution for superior handling and traction utilization. The Electronic Control Únit (ECÚ) provides information on engine rpm, airflow and transmission gear-ratio selection, while the VSA® ECÚ provides wheel-speed data. The SH-AWD® ECÚ also monitors steering angle, lateral G-forces, vehicle yaw rate and electromagnetic clutch engagement for the right and left rear axle shafts. Drive torque is calculated from ECÚ information, and then the acceleration situation, wheel spin, lateral G-force and steering angle are used to determine the front-to-rear torque distribution and the torque split between right and left rear wheels.

SH-AWD® operating parameters include:
• Úp to 90-percent of available torque can be transferred to the front wheels during normal cruising
• In hard cornering and under acceleration, up to 70-percent of available torque can be directed to the rear wheels to enhance vehicle dynamics
• Úp to 100-percent of the torque sent to the rear axle can be applied to either the left or right rear wheel, depending on conditions

SH-AWD® System Layout
The MDX SH-AWD® is a full-time all-wheel-drive system that requires no driver interaction or monitoring, thanks to a torque-transfer unit that is bolted directly to the front-mounted transaxle. The torque-transfer unit receives torque from a helical gear that is attached to the front differential's ring gear, and a short horizontal shaft and hypoid gear set within the torque-transfer unit's case send power to the rear propeller shaft, which in turn transfers power to the rear drive unit.

The MDX SH-AWD® rear drive unit is constantly overdriven by 1.7-percent and the resulting overdrive effect is regulated by left- and right-side electromagnetic clutch packs (located in the rear differential) that independently control the power delivered to each rear wheel.

Direct electromagnetic clutch systems mounted on either side of the hypoid gear that drives the rear axles control the amount of torque sent to each rear wheel and provide a limited-slip differential function when needed. The clutches can be controlled as a pair to alter front/rear torque split or they can be controlled independently to allow 100-percent of available rear axle torque to go to just one rear wheel.

An electromagnetic coil modulates the pressure controlling each clutch pack, which changes the speed of the sun gear within the rear differential's planetary gear set to control the amount of torque sent to each wheel. Electromagnetic control of the clutches permits the torque delivery to each rear wheel to be proportioned in an exceptionally quick and precise manner, which reduces wheel-slip in low-traction conditions.

The clutch packs and their friction material are carefully designed to withstand the small amount of continuous slip between front and rear axles created by the 1.7-percent speed differential – all while delivering the durability expected of an Acura product. Through an oil-temperature sensor, the SH-AWD® Control Únit monitors the rear differential's clutch-plate coefficient of friction (which changes with temperature) in each clutch pack and then adjusts the voltage to each electromagnetic coil to compensate. As total vehicle miles accumulate, the SH-AWD® Control Únit uses data from a feedback loop to adjust the voltage supplied to the electromagnetic coils to compensate for any clutch wear, ensuring optimal and consistent transmission of torque.

Trailer Hitch and Trailer Hitch ATF Cooler Kit (Optional)
When the need to tow arises, put your MDX to work by adding the Trailer Hitch. A receiver-style hitch accommodates a variety of trailer coupler designs, and includes a draw bar, retaining pin, clip, and wiring harness with 7-pin round-style connector. A 1-7/8 -inch or 2-inch balls available separately. The optional Trailer Hitch ATF Cooler Kit will allow towing of up to 5,000 lbs.

Remote Engine Start with Vehicle Feedback
The MDX with Advance and Entertainment Packages provides the ability to start the vehicle's engine remotely. This enables drivers to start their MDX, thereby activating the climate control system before they get to the vehicle – perfect for hot or cold days. The remote is designed to have a range of operation of at least 300 feet. To start the engine remotely, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. When the engine is started remotely, the wipers, lighting and audio systems remain off, and the security system remains set. The engine will run for up to 10 minutes after remote starting, and then shut off automatically if the owner doesn't reach the vehicle within that time. When the owner does get to the MDX within 10 minutes, the engine will keep running while the owner unlocks the vehicle and gets in.

This system also provides feedback to the owner to confirm whether the engine is running or the vehicle is locked. The remote has three LED indicators: amber, green and red. To confirm engine start, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. The amber indicator will flash while the remote communicates with the vehicle. If the engine is running, the green LED will then light for one second. If the engine is not running, the red indicator will light for one second. To verify whether the vehicle is locked, the owner presses the LOCK button once. After the amber light comes on, either the green or red LED will light for one second to indicate that the vehicle is locked or not, respectively. And if the red LED flashes three times, the vehicle is out of the remote's range.

This system can provide owners with the comfort of a pre-warmed vehicle on a cold winter morning - or a pre-cooled interior on hot days. Plus, it adds the convenience and confidence of knowing that their vehicle is securely locked, even far beyond the range of a typical remote.

The 2014 MDX design, created in the Acura Design Studio in Torrance, California, was developed under the theme of 'Aero Sculpture.' With its alluring proportions, smooth, arching bodylines and confident stance, the 2014 MDX communicates a look of sophistication and elegance while delivering new levels of aerodynamic efficiency. Its five-point grille features a chrome surround and a decisive satin sash with black grille bars. The new MDX is the second new Acura vehicle to feature Acura's signature Jewel Eye™ LED headlights, with five LED elements per side, providing a unique and sophisticated appearance day and night. The side mirror-mounted turn signals, taillights, CHMSL and license-plate lights are also LED, with a look that is uniquely MDX.

The MDX body sides are defined by a tall and dramatic beltline, windswept roofline, decisive upper and lower character lines, stylized chrome door handles integrated into the upper character line, dynamic fender arches, and chrome window surrounds. The Advance and Entertainment Packages also has elegantly functional chrome roof rails, and all models include a functional rear spoiler.


2.0 inches longer, 1.5 inches lower, and 1.3 inches narrower than the model it replaces, the MDX is designed to cheat the wind with 2-percent less frontal area and a 16-percent lower coefficient of drag. This makes the third-generation MDX the most efficient vehicle in its luxury class, garnering higher fuel economy ratings than the previous-generation model in every EPA rating category including City, Highway and Combined. In addition to the 16-percent improvement in aerodynamic drag, the new MDX is more luxurious in appearance.

The MDX body is highly rigid with torsional rigidity improved by 12 percent. In addition, the 2014 MDX boasts a 67 percent increase in rigidity at critical suspension mounting points, which combined with overall body rigidity gains provides the foundation for its confident handling capabilities, refined ride quality and reduced cabin noise and vibration.

The MDX incorporates Acura's next-generation Advanced Compatibility Engineering™ (ACE™) front frame structure for enhanced frontal collision protection. Collision protection is further enhanced by the world's first ultra-high strength steel, one-piece stiffener ring – comprising the A-pillar and B-pillar, roof rail and lower frame member – for improved management of collision energy in frontal offset and side impacts and roof load management in the event of a rollover.

LED Lighting
The MDX's new Jewel Eye™ light-emitting diode (LED) headlight arrays provide brighter and sharper nighttime illumination and visibility compared to contemporary high-intensity discharge (HID) headlights – and far superior performance compared to traditional halogen projector beams. Besides improving driver confidence and passive safety, the LED headlights also use less energy, helping to enhance fuel efficiency by reducing engine loads. In addition, the LED headlights last up to three times longer than HID headlights and up to six times longer than halogen headlights – contributing to less frequent replacement and the associated cost savings.

Acoustic Glass
The MDX utilizes 4.5-mm thick, 3-layer acoustic windshield and 4.8 mm front door glass mitigates wind, road and traffic noise in the cabin. The rear side windows are also thicker than in the previous MDX – up from 3.5 mm to 5.0 mm.

The unique styling of the LED array helps give the MDX a distinctive appearance, both day and night. The array includes five individual LEDs per side, covered by a composite lens and accented by a chrome trim surround. All 5 LEDs illuminate as DRLs. The three outer also function as the low-beams, while the inside two LEDs serve as high-beams. An auto on-off function is included, and the low-beams are also keyed to the remote key fob operation.

The MDX also features LED taillights, license-plate illumination and side view mirror-mounted puddle lights (and for overhead and accent lighting in the MDX cabin). LED fog lights are optional on the MDX.

Únderbody Airflow
Carefully managing underbody airflow helps reduce turbulence and drag for improved fuel efficiency, while also enhancing stability at highway speeds. Strategically placed aerodynamic under-body components – including front splash shields, an engine exit cover, and a mid-floor undercover – help smooth airflow between the body and road surface, while also helping to minimize power-robbing turbulence and drag. A front air dam with a broad wickerbill, along with strakes positioned ahead of the rear tires, further improves efficient airflow. The result is increased fuel efficiency, increased stability and reduced wind noise on the highway.

Advanced Materials, Lower Weight
With high-strength steel, aluminum and magnesium totaling 64-percent of its body structure, at a curb weight of 4,297 pounds the 2014 MDX is 275 pounds lighter than the previous model. It is also has the lightest published weight in its segment, which directly contributes to improved acceleration, light and nimble handling, and class-leading fuel economy ratings.

The MDX is assembled from steel stampings that are robotically welded together to form a single, lightweight unit-body with a high level of rigidity. A variety of advanced materials and techniques give this structure exceptional strength and uniformity. One is high-strength steel, which composes 59 percent of the body structure by weight, including the use of 1,500-megapascal ultra-high strength 'hot-stamped' steel in 7 percent of the body, enhancing collision protection while minimizing vehicle weight.

An example of high-strength components in the MDX are the one-piece stiffener rings around the front doors, a world's first technology. Formed from a single piece of hot-stamped steel, each ring provides immense strength for enhanced performance in frontal offset (small overlap) and side impacts, as well as enhanced roof crush protection. Likewise, the rigid tailgate opening is engineered to distribute loads through the rear suspension mounts, further aiding body stiffness.

The MDX steering hanger beam is made of a magnesium casting, which spans the entire width of the interior (behind the instrument panel). This new three-piece component replaces the 26-piece aluminum version used in the previous MDX and saves 7.5 pounds while reducing the potential for intrusion of the steering column into the cabin in a frontal collision.

Light weight is of particular interest to driving enthusiasts. Performance can be increased by reducing weight, as is continually proven on the racetrack (including the Nürburgring Nordschleife road course in Germany, where the 2014 MDX was tested and validated). Racing experience and supercomputers were both used to reduce weight in the new MDX unit-body without sacrificing strength. This enhances its power-to-weight ratio, as well as handling abilities and braking performance.

Noise, Vibration and Harshness (NVH) Reduction
To create a premium driving experience, extensive research and countermeasures were applied to help reduce noise, vibration and harshness (NVH) throughout the new MDX. Acura engineers began by working to eliminate NVH at its source with technologies such as a highly rigid unit-body, tightly controlled manufacturing tolerances, a highly rigid aluminum-alloy engine block and forged-steel crankshaft, electronically calibrated engine mounts, careful aerodynamic tailoring, acoustic glass, and more.

Active Control Engine Mounts
Debuting on the 2014 MDX is an Active Control Engine Mount system (ACM) that minimizes the effects of engine vibration as the Variable Cylinder Management (VCM) system switches between 3- and 6-cylinder modes. Special vibration sensors alert the Electronic Control Únit (ECÚ) to direct ACM actuators – which are positioned at the front and rear of the engine – to cancel vibration. Additionally, an Active Sound Control system, operating through the vehicle's stereo speakers, further reduces low-frequencies associated with 3-cylinder operation by producing a reverse-phase sound profile. (See Powertrain and Interior sections for more information.)

Road Noise Reduction

To help isolate road noise and reduce its intrusion into the cabin, the lower suspension components attach to fully isolated steel subframes that ride on specially tuned bushings. In addition, improved door sealing and melt sheet, an asphalt-based sound-damping material, is bonded to the floor and wheel arches of all Acura vehicles at the time of assembly.

Wind Noise Reduction
Smoothing airflow over the complex shape of a vehicle body can help reduce not only aerodynamic drag, but also the wind noise that is transmitted to the cabin. The 2014 MDX was texted extensively in a full-sized wind tunnel. Together with computer simulations, wind-tunnel testing combined with sophisticated computer modeling allows engineers to identify areas of the body that are prone to wind noise – and then analyze fine detail changes with a high degree of accuracy.

One result of this testing is the MDX's body-panel fit, which helps minimize gaps that create turbulence and wind noise when the vehicle is traveling at speed. Other details include carefully styled A-pillars and side mirrors, a flush-fitting windshield, moonroof and side glass, and numerous other design details that all contribute to the low wind-noise characteristics of the 2014 MDX.

Wind-noise attenuation details also include components that are not visible. For instance, the MDX's body sections are isolated using 22 clip-in foam inserts that expand during the baking cycles of the body painting process. This material reduces wind noise transmitted into the vehicle. The fin-type 2.7-inch high antenna used for XM® Radio, AcuraLink and engine remote start, is positioned at the rear of the roof panel and is designed for low wind noise at speed. The AM/FM radio antenna is laminated into the right rear side window.

Outside Mirrors with Reverse Gear Tilt-Down
To improve convenience while parallel parking, the MDX's aerodynamically sculpted outside mirrors have a reverse-gear tilt-down feature that allows the driver to see the curb or curbside objects. Either the left- or right-hand mirror can be selected to automatically tilt down when reversing. After shifting into reverse, the driver simply moves the mirror-adjustment selector switch position to either the right or left. The corresponding mirror then tilts down to provide a clear view of the curb or curbside on that side of the vehicle. The mirror automatically returns to its previous position when the gear-selector lever is moved out of Reverse.

Auto-Dimming Side Mirrors (Advance and Entertainment Packages)
Included in the Advance and Entertainment Packages, auto-dimming side mirrors use the same activation sensor as the MDX's auto-dimming inside rearview mirror. The auto-dimming function of all three mirrors helps reduce glare during nighttime driving, especially from the headlights of following vehicles.

Included in the Technology Package and up, LED puddle lights, mounted on the bottom of the sideview mirror housings, add convenience for the driver and front passenger at night. These LEDs automatically illuminate when the driver approaches and the vehicle detects the remote.

Expanded View Driver's Mirror
A new Expanded View Driver's Mirror performs like two mirrors in one. The larger, inset portion of the mirror is relatively flat and works like a conventional sideview mirror to show objects to the side of the vehicle. The outer portion of the mirror is optically convex and functions as a wide-angle mirror to expand the driver's view to the side by approximately 43-percent, helping to reduce the blind-zone area.

Rain-Sensing Wipers (Technology and up)
MDX models with the Technology Package include rain-sensing wipers that automatically activate if water is detected on the windshield. Designed to cover the maximum possible windshield area, the left (driver) and right (front passenger) windshield wipers are 26 and 20 inches long, respectively. The rear wiper is 14 inches long.

One-Touch Turn Signals
The MDX's one-touch turn signals improve convenience for the driver when making routine lane changes. With this system, a quick movement of the turn-signal lever (between 0.4 sec. and 1 sec.) provides three blinks of the turn signals – an ideal strategy for changing lanes. Holding the lever for one second or longer (past the 'click point') provides continuous blinking, such as for signaling a turn or exiting a thoroughfare.

Parking Sensors (Advance and Entertainment Packages)
The Advance and Entertainement Packages includes parking sensors (4 front and 4 rear), located on the front and rear bumpers. The sensors use ultrasonic wave technology to detect nearby obstacles. If an object is detected, the system will sound an audible alert and can display a warning icon in the Multi-Information Display (MID) and upper display.

Alert sound characteristics change depending on how close the MDX is to the object. The system starts with slow intermittent beeps when an object is first detected, and progresses to quick intermittent beeps as the MDX moves closer. The system will sound a continuous beep when the vehicle is within a few inches of the object.

Note that the parking sensors cannot detect all obstacles, and that the driver is always responsible for making sure the path is clear when operating the vehicle.

All-New 2014 Acura MDX Debuts at the New York International Auto Show

2014 Acura MDXThird-generation MDX raises the bar with more performance, class-leading fuel economy ratings, innovative interior features and signature Acura technologies 2014 Acura MDX
Acura today unveiled the all-new 2014 MDX luxury SÚV at the 2013 New York International Auto Show (NYIAS). Built on a completely new platform, the seven-passenger MDX offers improved ride comfort, a more versatile and luxurious cabin, increased fuel efficiency and enhanced dynamic performance. The MDX will also be offered for the first time in a more affordable and even more fuel-efficient two-wheel-drive configuration.

2014 Acura MDX
'Building on the award-winning dynamic performance of the previous model, the third-generation MDX adds new levels of luxury comfort, family functionality and fuel efficiency to once again set the luxury SÚV benchmark,' said Jeff Conrad, vice president and general manager of Acura Sales. 'From Nürburgring-tuned dynamics and thoughtful interior appointments, to the addition of a new two-wheel-drive model, the all-new MDX continues Acura's direction of creating vehicles that advance the synergy between man and machine.'

2014 Acura MDX
The 2014 Acura MDX is powered by an all-new direct-injected 24-valve 3.5-liter i-VTEC V-6 engine with Variable Cylinder Management™ (VCM™), producing 290 horsepower and 267 lb.-ft. of torque. The MDX's engine architecture is shared with two racecars that recently finished First and Second in the LMP2 class at the 12 Hours of Sebring endurance race in the American Le Mans Series (ALMS). Employing a 6-speed automatic transmission with Sport Mode and Sequential SportShift Paddle Shifters, the new MDX will be offered in both Super Handling All-Wheel Drive™ (SH-AWD™) and two-wheel-drive drivetrain variants, both featuring Acura's new Agile Handling Assist technology.

2014 Acura MDX
Matched to the highly efficient Earth Dreams Technology engine and the SH-AWD drivetrain, the 2014 MDX has an EPA fuel economy rating of 18/27/21 mpg1 (city/highway/combined), while the new front-wheel-drive model is EPA rated at 20/28/23 mpg1 (city/highway/combined).

While achieving even higher fuel economy ratings, the MDX remains a true driver's SÚV with enhanced dynamic performance, including quicker acceleration, more responsive braking and even more precise steering feel. Tuned and tested on the grueling Nürburgring racing circuit in Germany, the lighter and more dynamic new 2014 MDX with SH-AWD bests the previous model's lap time by eight seconds.

To satisfy the preferences of multiple drivers in any family, the 2014 MDX features an all-new Integrated Dynamic System (IDS) with three modes: Sport, Normal and Comfort. IDS adjusts steering effort, throttle response, SH-AWD and active sound to suit the tastes of the driver. The MDX's new Amplitude Reactive Dampers, MacPherson strut front suspension and new multi-link rear suspension enable its more nimble and responsive handling and improved ride quality. 18-inch aluminum alloy wheels and 245/60-18 tires come standard on the MDX. Technology and Advance grades are equipped with 19-inch aluminum alloy wheels and 245/55-19 tires.

Body and Styling
The 2014 MDX body applies more than 55 percent advanced lightweight materials – including high strength steel, aluminum and magnesium – resulting in a vehicle that is both more rigid and lightweight, with total vehicle weight reduced 275 pounds from the previous model. Measuring 193.6 inches in overall length, 77.2 inches in overall width (excluding door mirrors), 67.6 inches in overall height, and riding on a 111-inch wheelbase (up 2.75 inches from the previous model), the new MDX boasts an 'Executive Aero Sculpture' exterior design that lends it a sleek, tailored and sophisticated appearance. The aerodynamic body design – refined by engineers in a new wind tunnel at the company's Ohio R&D center – helps the MDX achieve a more than 17 percent improvement in aerodynamic efficiency, making it one of the most aerodynamic and fuel-efficient luxury SÚVs on the road.

The 2014 MDX also takes a big step up in luxury comfort and quiet. The MDX's dynamically tuned platform, more airtight body and triple path isolated dampers, along with the use of new sound-deadening materials, such as acoustic glass and expanding body sealers, and Active Noise Control technology, make this the quietest and most composed MDX yet.

Equally adept at carrying clients and kids, the new MDX boasts a luxurious and versatile interior. The revised body dimensions and new, more compact multi-link rear suspension, combined with innovative new technologies on the second-row seats, significantly improve third-row access and all-around passenger comfort. Third-row ingress and egress is significantly improved by a two-inch lower step-in height and three-inch wider entryway, and by the introduction of a new One-Touch Walk-In feature. With a single press of the illuminated One-Touch Walk-In button, the second-row seats automatically fold and slide to their forward-most position. The second-row seats now feature a four-position recline and a new Extended Slide capability that provides six inches of total fore-aft seat adjustment for optimal balance between second- and third-row legroom. Rear cargo capacity is also improved and includes a new underfloor storage area.

Úp front, there is a 10-way power adjustable and heated driver's seat and an 8-way power and heated passenger seat. The MDX also addresses a major shortcoming of many luxury SÚVs – available front-seat storage space – with a spacious new center console that can accommodate a purse, laptop case, or a pair of iPads®. The MDX's luxury quotient is further boosted by its upgraded interior appointments, including premium leather-trimmed interior, silver plated accents, LED overhead and cabin accent lighting, along with new optional luxury features, such as Smart Entry, second-row sunshades, remote engine start, and auto-linked air conditioning and climate-controlled seats.

Acura Signature Technology
In addition, the 2014 Acura MDX harnesses a range of Acura signature technologies, including Acura Jewel Eye™ LED headlights, more powerful Acura/ELS Studio premium audio system, and the next-generation AcuraLink™ connectivity system with AcuraLink Real-Time Traffic™, featuring freeway traffic and surface street conditions (free for the first three years). In addition to the traffic services, the AcuraLink™ cloud-based connected car system offers an assortment of media, convenience, information and security features via an embedded cellular system and compatible web-enabled smartphones.

Both the AcuraLink™ and Acura/ELS Studio system take advantage of a 7-inch color On Demand Multi-Úse Display™ (ODMD) touchscreen with haptic feedback and an 8-inch Color Information Display. The addition of the ODMD, along with other interior changes, allowed engineers to reduce the number of hard buttons in the center stack from 41 to just nine. The available Entertainment package adds a DVD Rear Entertainment system with a 9-inch full VGA screen for the rear seats, while the Advance package replaces the 9-inch monitor with an ultra-wide, 16.2-inch full VGA screen with HDMI compatibility for devices such as a game console.

The 2014 MDX offers a host of innovative driver assistive and visibility technologies, including a Multi-Angle Rearview Camera and available Lane Keeping Assist System (LKAS), Adaptive Cruise Control (ACC) with Low-Speed Follow, Blind Spot Information (BSI), and Collision Mitigation Braking System (CMBS).

The third-generation MDX is expected to achieve top-level safety ratings, including a 5-star Overall Vehicle Score from NHTSA and a TOP SAFETY PICK+ rating from the Insurance Institute for Highway Safety (IIHS), including the highest possible rating of GOOD in the Institute's new small-offset frontal collision test.

The new MDX is equipped with a broad array of advanced safety technologies, including the next generation Advanced Compatibility Engineering™ II (ACE™ II) body structure, 4-wheel Anti-Lock Braking System (ABS) with Electronic Brake Distribution (EBD) and Brake Assist, Vehicle Stability Assist™ (VSA®) with Traction Control, and airbags (front, front side, driver's knee and side curtain with rollover sensor), as well as the available Forward Collision Warning (FCW) and Lane Departure Warning (LDW) systems.

The 2014 Acura MDX is scheduled to go on sale at Ú.S. Acura dealers nationwide this summer and will be available in four grades – the well-equipped MDX, the robust MDX with Technology package, the rear-passenger-friendly MDX with Technology and Entertainment packages, and the top-of-the-line MDX with Advance and Entertainment packages. The 2014 MDX was designed and developed in the Ú.S. and will be built at the Lincoln, Alabama plant using domestic and globally sourced parts. Pricing details will be announced closer to launch.
