CADILLAC CTS INTRODUCES NEW MODEL WITH 2.8L ENGINE FOR 2005
The 2005 CTS builds on Cadillac's century-long tradition of technology and design innovation, and is a modern interpretation of the strikingly beautiful cars that made Cadillac famous. Built on GM's acclaimed Sigma rear-wheel-drive architecture, CTS was rigorously tested at the famed Nurburgring racetrack in Germany.
For 2005, CTS debuts a new entry-level model with a new 2.8L engine that makes 210 horsepower (156 kw) and 195 lb.-ft. of torque (265 Nm). The 2.8L V-6 VVT is a modified version of the 3.6L VVT CTS engine. Braking and suspension capabilities remain the same. The new model is intended to widen the CTS and Cadillac demographic base to include younger buyers. Production begins in October 2004. Both engines can be mated to a new six-speed manual transmission, and the 2.8L also is available with the five-speed automatic transmission. (posted on conceptcarz.com)
The 2005 CTS also has a new instrument cluster, 16-inch painted wheels, 16-inch machined wheels, and three new exterior colors: Stealth Gray, Sand Storm and Moonstone. 2.8L V-6 VVT
As the second-produced variant of GM's new global V-6 engine family, the new 2.8L V-6 VVT was designed using the latest advanced engineering tools. It is an all-aluminum 60-degree dual overhead cam, four-valve-per-cylinder design developing 210 hp (156 kw) at 6500 rpm and 195 lb.-ft. (265 Nm) of torque at 3200 rpm. Consistent with the 60 degree V-6 design, the engine employs a wide range of advanced technologies, including fully variable valve timing of the intake and exhaust valves and a dual-stage variable intake manifold to deliver outstanding flexibility, fuel economy and emissions control. The 2.8L V-6 comes mated to a new six-speed manual transmission or the Hydra-Matic 5L40-E automatic transmission. (posted on conceptcarz.com) 3.6L V-6 VVT engine

The 2.8L also is available with the six-speed manual.
The six-speed transmission is fully synchronized (including reverse), with a single overdrive. This allows for lower propshaft speeds and improved NVH. The transmission is rated for 400 Nm (295 horse power) and its unique architecture is such that the gear inertias are lower, resulting in significantly lower shift efforts compared to conventional RWD manual transmissions.
The compact, state-of-the-art 5L40-E automatic transmission features a full complement of advanced electronic control capabilities. These include a shift mode button that allows the driver to select between 'sport,' 'winter' and 'economy' modes. Another electronic feature is also a first for GM: engine braking in all five gears, giving the automatic the same sporty feel as a downshifting manual. Dramatic design
The design team gave CTS a uniquely Cadillac look. Its lean, chiseled body features sheer forms, sharp edges and crisp intersecting lines that honor Cadillac's storied past and look to the future.
Conventional Cadillac cues, including the grille and exterior lighting, have been updated for the CTS. Cadillac's traditional vertical headlamps and taillamps first appeared in 1965, and CTS refines the tradition. CTS' integrated headlamps convey the high-tech image of optical instruments and high-end camera lenses. Thin and tall, they create more space for the large, louvered grille.
The interior provides all the amenities that luxury customers have come to expect, with the emphasis on comfort and convenience. It uses warm, rich materials to contrast with the cool, computer-like, high-tech cockpit appearance, balancing the contemporary feel with touches of traditional luxury. Wooden surfaces are used sparingly on the steering wheel, shifter knob and door pulls. New Sigma architecture
The CTS' Sigma architecture is the first usage of ultra high-strength steel at GM, and the first time the steel has been incorporated as a welded member of the structure. In the past, ultra high-strength steel was limited to applications such as bumpers, where bolts were used for attachment. Últra high-strength steel permits the use of thinner, lighter steel, which reduces mass yet still allows proper energy absorption and reduces intrusion into the passenger compartment in an accident. Comprehensive safety and security
CTS has six air bags, including dual-stage frontal air bags for front-seat passengers. Head-curtain side air bags help protect front and outboard rear passengers. It also has Xenon high-intensity discharge (HID) halogen headlamps, StabiliTrak and OnStar, and several other safety and security features.
StabiliTrak assists the vehicle in maintaining the driver's intended path by applying a brake force at any corner of the vehicle independent of the driver's use of the brake pedal.
StabiliTrak uses an accelerator pedal position sensor, a brake master cylinder pressure sensor and a steering wheel angle sensor as inputs to interpret the driver's desired path and whether to accelerate or decelerate the vehicle. StabiliTrak also uses these sensors plus a lateral accelerometer and yaw rate sensor to determine the vehicle's actual path.
If the difference between the driver's desired path and the vehicle's actual path becomes great enough, StabiliTrak takes appropriate action to assist the driver with maintaining the desired path. If the vehicle begins to 'snowplow,' or understeer, StabiliTrak applies the inside rear brake to help turn the vehicle. If the vehicle begins to fishtail, or oversteer, StabiliTrak applies the outside front brake to straighten the vehicle. StabiliTrak is integrated with the traction control and ABS systems.
OnStar is the leading provider of in-vehicle safety, security and information services in the Únited States and Canada. Úsing the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Personal Calling that allows drivers to make and receive hands-free, voice-activated phone calls using a powerful three-watt system and external antenna for greater reception.
All 2005 Cadillac owners in the Ú.S. will receive 12 months of complimentary access to Cadillac VirtualAdvisor by OnStar. Cadillac Virtual Advisor service begins at activation of OnStar Personal Calling. Cadillac Virtual Advisor provides three-day weather forecasts and traffic reports within pre-selected ranges of 5, 10 or 15 miles of the vehicle's location in most major markets. Cadillac Virtual Advisor also monitors traffic for up to three personalized routes and reports information on up to 10 selected stocks on the DJI and NASDAQ markets – all at the touch of a single button.Source - Cadillac
CADILLAC CTS-V DELIVERS PERFORMANCE, POWER, HANDLING AND STYLING
The CTS-Vprovides high-performance driving enthusiasts with a serious, credible alternative to imports in the highly competitive, low-volume luxury performance segment, including the BMW M-Series, Mercedes-Benz AMG Series and Audi S-Series.
The V-Series has been designed to take Cadillac's performance credentials to an entirely new level. With 400 horsepower (298 kw), CTS-V is the most powerful production model Cadillac has ever offered.
Based on Cadillac's performance-oriented rear-drive Sigma architecture, CTS-V is a highly refined high-performance luxury sedan designed for performance enthusiast drivers.
Like the original CTS, CTS-V was refined and validated at Germany's famed Nurburgring racetrack to meet the expectations of the world's most avid driving enthusiasts.
For 2005, two new exterior colors, Red Line (extra charge) and Stealth Gray will debut, along with a Light Gray interior (available midyear).
Serious performance credentials
The four-door, rear-wheel-drive CTS-V has the overhead valve 5.7L V-8 LS6 engine producing 400 horsepower (298 kw) and 395 lb.-ft. (533 Nm) of torque. It makes 0-60 mph in 4.6 seconds and has a top speed of 163 mph (262 km).
Engine highlights include an aluminum block, two-valve cylinder heads with revisions to the air induction system, and an enlarged dual exhaust system for an impressive V-8 sound. The LS6 V-8 provides CTS-V with racetrack-proven performance, along with smooth, quiet operation and outstanding reliability, durability and quality. The engine's lightweight aluminum construction – including its cylinder heads and block – delivers an excellent power-to-weight ratio (1:9.6) and good chassis balance (54 percent front / 46 percent rear).
Power is delivered through the six-speed manual Tremec T56 transmission that features a dual mass flywheel for reduced noise and vibration harshness. A heavy-duty, increased diameter, 70-mm prop shaft is used for the higher torque requirements. The limited-slip rear axle is fitted with a 3.73:1 final drive ratio to optimize acceleration.
To help develop and manage its higher horsepower and torque output, and to reduce noise, vibration and harshness, the CTS-V received several performance modifications including:
High-profile camshaftopens the valves faster and higher, enabling more air to flow into and out of the combustion chambers and contributing to horsepower gains
High-strength pistonshelp increase engine durability, particularly under high-performance operating conditions
Revised valves and stiffer valve springsbetter accommodate valve operation with the high-lift cam, hollow intake valves reduce mass and permit extremely high cam lift, and the sodium-filled exhaust valves help ensure proper cooling
Enhanced induction systemenables enhanced engine breathing, helping to increase horsepower output
High-flow intake manifolddelivers high amounts of airflow to the intake ports, helping to ensure a broad torque curve while delivering maximum power
High-flow fuel injectorsdeliver fuel at the faster rate needed due to increased intake airflow
Reconfigured exhaust manifoldspermit increased exhaust flow while maintaining low levels of noise
Dual exhaustconstructed of 2.5-inch (159-mm) diameter stainless steel pipe to help minimize back pressure, increase horsepower and ensure proper exhaust tone. Investment-cast stainless steel tips cap the exhaust pipes
Engine coverhelps reduce underhood noise and ties directly to the exterior performance styling of the vehicle with the Cadillac wreath and crest in its center and V-Series identification positioned over each cylinder bank
Following extensive development at the Nurburgring, the racing-inspired Brembo 14-inch (355-mm) front and 14.4-inch (365-mm) rear disc brakes provide remarkable deceleration and reduced braking distances with aluminum four-piston calipers on all four corners. Included on the caliper casting is distinctive V-Series identification. Specific seven-spoke 18-inch by 8.5-inch aluminum, six-lug wheels and Goodyear P245/45WR18 EMT (run flat) tires are standard.
To handle the high-output horsepower and torque, CTS-V is equipped with an extremely robust front and rear suspension. Specific refinements include:
Hydroformed front/rear cradleshandle the greater mass of the LS6 engine (front) and 180 lb.-ft. (244 Nm) increase in torque surging through the driveline (rear) as well as enhancing NVH performance
Larger stabilizer bars decrease body roll by increasing roll stiffness
Increased front/rear spring ratesenhance performance-oriented handling characteristics
Larger monotube front shocksincrease damping capacity and provide better thermal performance
Nivomat rear shocksautomatically adapt spring and damping rates to changing load conditions for enhanced handling and ride performance
Performance-tuned elastomeric ride bushingsfitted to aluminum control arms to bring precise on-center feel, enhance linear performance under high-speed braking and reduce control arm movement at high speeds
The StabiliTrak stability enhancement system assists the vehicle in maintaining the driver's intended path by applying a brake force at any corner of the vehicle independent of the driver's use of the brake pedal. It is standard equipment and includes four driver-selected modes of operation, including a competition mode for better track performance. The extensive chassis tuning carries over from the 2004 model, including larger shock absorbers and 26.6-mm front and 21-mm rear stabilizer bars. Front and rear spring rates are increased by 27 percent from the CTS.
On the exterior, the CTS-V includes enhancements designed to increase performance, including a unique front fascia with an integrated aero splitter for better aerodynamics and brake ducts vented to cool front brakes. Stainless steel mesh grilles, both below and above the bumper, offer a unique front appearance and allow for free air flow into the engine compartment. Sides include a unique aero rocker design that flows into a specific rear fascia.
Únderneath the hood, a tower-to-tower cross-car brace has been installed for improved steering response and linearity under high-performance conditions. To help reduce underhood noise, a unique nylon cover, which features the Cadillac wreath and crest and V-Series logo, is fitted over the top of the engine.
A full dual exhaust system exits through the rear fascia and is capped with chrome oval exhaust tips. The 'V' logo appears on the deck lid and front fenders and also on brake calipers, rocker panel and the speedometer in the instrument cluster.
Interior geared toward performance driving
CTS-V offers a unique instrument cluster trimmed with satin chrome rings around each gauge. Aircraft-style, white lettering on a black field is used on gauges for better legibility. The instrument cluster also includes two driver information centers (DIC) located in the instrument panel. The left *** can display performance-oriented information including peak and momentary lateral acceleration, oil, transmission and coolant temperatures, and oil and tire pressure. The right *** indicates odometer, digital speedometer and reverse gear and skip-shift indicators.
Other interior design features include a three-spoke steering wheel with an aluminum bezel and specific controls for CTS-V. Satin chrome finishes also are used on the shift knob, door pulls and door handles. The center armrest has been lowered significantly for easier shifting during driving. Driver and passenger seats include adjustable lumbar and sueded fabric insert material to help maintain driver position in lateral maneuvers.
All engineering work for the CTS-V was performed by the GM Performance Division, an in-house center designed to explore potential enthusiast-oriented versions of production models. CTS-V will be produced at GM's Lansing Grand River assembly center, the award-winning manufacturing site for the CTS, SRX luxury utility and STS luxury sedan. (concept carz)Source - Cadillac
