The new Audi A4 Avant: Driving in a new dimension
• Attractive design, spacious and well thought-out luggage space
• Sporty technology layout and dynamic driving performance
• New generation of engines with higher performance and lower fuel consumption
Dynamic, elegant, and emotional; with the A4 sedan, Audi has already advanced into a new dimension. In a few weeks, the A4 Avant will follow: The most successful premium station wagon of its class offers, along with excellent drivability and uncompromising quality, a higher utility value for sports and recreation. This vehicle combines elegance and intelligent functionality.
The Audi A4 Avant is extending its lead. Based on the same technology layout as the sedan, the newly developed five-link front axle has been shifted farther forward. This ensures that the axle loads are perfectly distributed, thereby guaranteeing the highest precision and agility when it comes to handling. The Avant therefore also offers a new and fascinating driving experience similar to the one that led media experts to pronounce the sedan the best automobile in the midsize range.
Audi is launching the A4 Avant with five engine types to begin with: two gasoline engines and three diesel engines. These engines offer superior performance while reducing fuel consumption by more than 14 percent compared to the previous model – proof of Audi's successful efficiency strategy.
Audi's high technological competence is also expressed in the broadly diversified range of powertrains and in its numerous sport and comfort technologies – many of which originate directly from the premium class.Attractive station wagons called Avant: the design
The design of the new Audi A4 Avant is as exciting and dynamic as one would expect from a brand as design-oriented as Audi. The headlights are staged like a technological work of art. The Avant comes with daytime running lights as a standard feature; the xenon plus headlights consist of 14 white light-emitting diodes.
Compared to the forerunner model, the proportions have been reconfigured in a new and even sportier design. The front overhang has been shortened, and the engine hood and the wheel base have gained considerably in length. The flat D-posts lend the Audi A4 Avant a dynamic, coupe-like silhouette, while the rear design emphasizes its width with powerful, horizontal lines. The new A4 Avant measures 4.70 meters (15.42 feet) in length, almost 12 centimeters (4.72 inches) longer than its forerunner model. Its body is considerably more rigid and safer in build than its predecessor, yet is around 10 percent lighter at the same time.
With up to 1,430 liters in volume (50.50 cubic feet), the latest addition to the Audi family has the largest luggage capacity in its competitive field; in its basic configuration it holds 490 liters (129 gallons). The 60/40 split-fold rear seats also come with the option of a load-through hatch with separate ski and snowboard bag. The A4 Avant's trunk is lined with fine carpet and features intelligent details as standard such as a reversible cargo floor and a convenient cargo cover that retracts at a touch. Audi also offers luxury features such as an electro-mechanical drive for the rear tailgate or tie-down eyelets for securing luggage.Light and spacious: the interior
The ambience inside the new A4 Avant is light and spacious. The interior reflects Audi's strengths – the highest quality of workmanship, sophisticated looks, and logical, intuitive operation. The cockpit is driver-oriented; it borrows many features from the larger A8. Thanks to the new electro-mechanical parking brake, the manual parking brake was no longer necessary.
Even the standard climate control system has been completely redesigned. It supplies ten percent more cooling capacity, yet operates more efficiently than the previous system, thus saving about 0.2 liters of fuel per 100 km.
When it comes to safety, Audi has raised the bar, for example, with its combination of adaptive airbags, belt tensioners with variable belt force limiters and seat position sensors on the front seats. With this system, the force of the airbag deployment and belt tension level are selectively controlled depending on the seat position and the accident severity. In case of a rear-end collision, the backs of the front seats and the head rests support the upper body. This system is called Audi backguard and has received special praise during independent tests.The engines: more performance, less fuel consumption
The new Audi A4 Avant will be launched on the market with two powerful gasoline engines and two diesel engines, thus covering a range of 105 kW (143 hp) to 195 kW (265 hp). The 2.0 TDI generating 125 kW (170 hp) will be added later to round out the range. All the engines have FSI and TDI direct fuel injection technology and the three four-cylinder engines reach high torques thanks to turbocharger technology. On average, the engine performance in this model series has increased by almost eight percent. At the same time, fuel consumption in the gasoline engines has dropped by almost 12 percent, and the TDI engines by almost nine percent.
The new 3.2 FSI is the most powerful engine that comes with the new A4 Avant. It has an output of 195 kW (265 hp) and reaches 330 Nm (243.40 lb-ft) of torque between 3,000 and 5,000 rpm. Enhancements to the V6 include considerably lower inner friction and a valve actuation system called the Audi Valvelift System, which varies the stroke of the intake valves.
The 3.2 FSI delivers sport-driven performance in any situation. It powers the A4 Avant from zero to 100 km/h (62.14 mph) in just 6.4 seconds and on up to a top speed of 250 km/h (155.34 mph). At the same time, fuel consumption has dropped by 1.5 liters (0.40 gallons) compared to its predecessor.
The 1.8 TFSI, too, is a highly efficient engine. The compact and light four-cylinder unit has an output of 118 kW (160 hp) and reaches 250 Nm (184.39 lb-ft) of torque between 1,500 and 4,500 rpm. Direct gasoline injection and turbocharging create the ideal combination in this model. The 1.8 liter engine responds spontaneously and provides a highly refined driving experience. It powers the car from zero to 100 km/h (62.14 mph) in 8.9 seconds and on up to a top speed of 218 km/h (135.46 mph).
The 3.0 TDI engine in the Audi A4 Avant comes across as a widely new engine, particularly when it comes to the fuel injection system and the turbo. This three liter diesel unit, which is firmly coupled to the manual transmission, has an output of 176 kW (240 hp) and reaches a torque of 500 Nm (368.78 lb-ft) between 1,500 and 3,000 rpm. Its performance figures – from zero to 100 km/h (62.14 mph) in 6.3 seconds, a top speed of 250 km/h (155.34 mph) – demonstrate this engine's dynamic character.
The 2.0 TDI has a new common rail fuel injection system that guarantees refined running; other innovations include the turbo and the piston geometry. Audi offers the two liter diesel engine in two versions: one developing 105 kW (143 hp) and 320 Nm (236.02 lb-ft) of torque and the other generating 125 kW (170 hp) and 350 Nm (258.15 lb-ft) of torque. Both ensure powerful propulsion – the basic TDI accelerates the A4 Avant to 100 km/h (62.14 mph) in 9.7 seconds and facilitates a top speed of 208 km/h (129.25 mph). The more powerful of the two accelerates the Avant to 100 km/h (62.14 mph) in 8.6 seconds and on up to a top speed of 222 km/h (139.19 mph).
When it comes to power transmissions, customers can choose from a broad range of high-tech components. Six-speed manual and tiptronic transmissions (optional for the 3.2 FSI) transfer the engine's torque. For the 1.8 TFSI unit and the 2.0 TDI engine generating 105 kW (143 hp), the continuously variable multitronic transmission is also an option.
The 3.2 FSI and the 3.0 TDI come equipped with quattro permanent all-wheel drive as a standard feature. It distributes the forces under normal driving conditions at a ratio of 40 : 60 between the front and rear axle – a configuration that perfectly harmonizes the overall dynamic character of the new A4 Avant. If needed, the Torsen differential transfers the majority of the torque to the axle with the better traction.
In the driveline of the new A4 Avant, the differential has moved directly behind the engine. It has switched places with the clutch or the torque converter.
It was therefore possible to move the front axle 154 millimeters (6.06 inches) forward. This solution provides for a longer wheel base and for the perfect distribution of the axle loads, thus improving both handling and ride comfort equally.Redesigned from top to bottom: the dynamic suspension
The dynamic suspension of the new Audi A4 was redesigned from top to bottom. The pivot bearing and the five links of the front axle are also made of aluminum, just like the beam, which makes the front end of the body more rigid. The steering box is located far to the front and deep down to enable the steering impulse to go directly to the wheels via the tie-rods. The highly efficient servo pump in the sensitive rack-and-pinion steering improves fuel consumption by about 0.1 liter/100 km.
In the rear axle, Audi applied the track-controlled trapezoidal link principle from the larger A6 and A8 series. The suspension is made largely of aluminum; the separate layout of the springs and shock absorbers guarantees sensitive responsiveness. The new A4 Avant will roll off the production line on 16 inch and 17 inch alloy wheels, behind which are located powerful brakes. The electronic stabilization program (ESP) can be partially switched off when driving under 70 km/h (43.50 mph).
A package of innovative technology makes the driving experience even more dynamic and exciting. The optional Audi drive select control system accesses various technology components, depending on which upgrade the customer has selected. In the basic version, it influences the engine's gas intake, the tiptronic shifting points, the multitronic and the power steering as well as the steering angle of the steering wheel. By pressing a button, the driver determines whether these components should work in a comfortable, average or sporty mode. If the car is equipped with the MMI operating system, a fourth, individually programmable mode is available.
Audi drive select requires at least one of the following two high-end components. One is an adaptive controller for the shock absorbers which is connected to a sports suspension and lowers the body by about 20 millimeters (0.79 inches).
The second component is the Audi dynamic steering that operates with a superposition gear. It varies the steering ratio continuously by almost 100 percent depending on the speed driven. In the limit range, it stabilizes the new A4 Avant thanks to its lightning-fast steering interventions. The system is also extremely useful when understeering occurs.Even greater supremacy: assistance systems
Audi equips the new Avant, upon request, with a complete range of high-tech systems that make driving an even more supreme and relaxed experience. These include the Audi parking system (a parking aid; standard for the A4 Avant Ambiente), Audi lane assist (the lane departure warning system) and Audi side assist (which warns of hazards when changing lane). Adaptive cruise control maintains the distance to the vehicle in front.
Even when it comes to multimedia, the Audi A4 Avant sets new standards. ( posted on conceptcarz.com)
The Audi Music Interface (AMI) allows iPods to be connected. The navigation systems with MMI Basic plus or with DVD including MMI are also further upgrade options. They permit the integration of cell phones as Bluetooth car phones and are combined with the competition-beating MMI operating system. The top of the line when it comes to hi-fi enjoyment is the car's sound system from the leading Danish company Bang & Olufsen: A powerful 505 watt, ten-channel amplifier controls 14 speakers.
The new Audi A4 Avant will roll off the production line in the Attraction, Ambition, and Ambiente equipment lines. The dynamic S line offers the options of an exterior package and a sports package. The broad range of options includes luxury-class features such as air-conditioned comfort seats, the triple-zone climate control system, the advanced key which allows keyless access to the vehicle and vehicle start-up at the press of a button, and the dynamic cornering light system known as adaptive light. The large panoramic glass sunroof lights up the elegant interior. A new headlight assistant will be an additional feature in the future.
The A4 Avant will be available for sale in the spring in Germany and other European markets. The basic price of the Audi A4 Avant 1.8 TFSI Attraction model with an output of 88 kW (120 hp) will be €27,550 and it will be available in the fall.Source - Audi
Introduced in 1994, the Audi A4 was a compact executive vehicle built by the German automaker Audi that was the successor to the Audi 80. This vehicle holds the distinction of single-handedly reviving the Audi brand following its large sales slump two years prior. The A4 was available as a saloon/sedan or an estate/wagon. During the 2nd version the model was called the B6 and the 3rd generation was dubbed the B7. A Cabriolet version was also introduced, though it was not retained for the 4th generation which was called the B8. The A4 quickly became a favorite among luxury-car buyers thanks to its sleek look, well-appointed cabin, sharp handling and available Quattro all-wheel drive.
The interior featured a truly European ambience with its firm, comfortable seating, it also featured tight panel gaps, high-quality materials and gave a very supple ride and willing performance.
Internally, the first generation of the Audi A4 was known as the Typ 8D and was introduced in 1994 on the Volkswagen B5 platform which was shared with the fourth generation Volkswagen Passat. The platform featured a longitudinal engine and standard front-wheel drive though many enthusiasts preferred the optional Quattro four-wheel drive system. Originally the A4 was introduced as a four-door saloon/sedan, but the following year the Avant; Estate/wagon showed up the following year.
European customers could opt for a variety of engines that included between 1.6 and 2.8 liters, and a 1.9 L Diesel that was available with VW's new 'Pumpe Düse' technology that was capable of achieving a high power value of 110 PS. At the time, the Audi's 2.8 L V6 that was carried over from the original 80/90 was the only engine option that was available in North America until 1997.
The first model in the Volkswagen Group, the Audi A4 featured the new 1.8 L 20V motor with five valves per cylinder and was based on the unit Audi Sport had developed for their Supertouring race vehicle. Producing 150 PS, a turbocharged version had 155 ft/lb of torque. In 1996, this technology was added to the V6 family, beginning with the 2.8 L V6 30V which now produced 193 PS.
Based on the unit that Porsche had developed for their 964-generation 911, Audi introduced their new Tiptronic transmission on the B5 platform. Offering a choice of driving the vehicle as either a fully automatic operation or with a manual override of the gear ratios, the transmission was a conventional automatic gearbox with a torque converter.
In 1997 a revised B5 Audi A4 range was introduced at the Frankfurt Motor Show. Sales began in Europe in early 1998. Replacing the 2.8 L 12-valve was a newly introduced 2.8 L 30-valve engine. The range received an important addition, the 2.5 L V6 TDI diesel engine with 150 PS and standard Quattro and a six-speed gearbox, along with the new high-performance S4. New updates included new taillights, door handles, headlights, and other minor exterior and interior changes.
Halfway through the 1998 model year, the 1.8T engine was available outside of Europe and had its power output raised to 170 PS. The original KKK KO3 turbocharger was upgraded with a KO3s (sport) unit. The 30-valve unit that had been available in Europe for two years replaced the 12-valve V6 engine. An even higher performance RennSport model was introduced in 1999; the RS4 Avant which was available only in Avant body-style just like the RS2.
The Audi A4 introduced a hybrid version in 1997. Audi was the first European car manufacturer to put a hybrid vehicle into series production, the third generation Audi duo then based on the A4 Avant. Internally, the all new A4 model was dubbed the Typ 8E and was introduced in late 2000 and was now riding on the all new Volkswagen B6 platform.
The all-new styling of the Audi A4 was inspired on the C5; second generation Audi A6. The original 1.6 L base model didn't change, but most other petrol/gas engines received power upgrades or displacement increases. Now available in two additional versions, the 1.8 L 20-valve Turbo came with either 150 or 180 PS, this one came with a standard six-speed gearbox. The naturally aspirated 1.8 L straight-4 and 2.8 L V6 were replaced by 2.9 L and all-aluminum 3.0 L units. The most powerful of these was capable of 220 PS and 221 lb/ft of torque. Upgraded to 130 PS, the 1.9 TDI engine was now available with Quattro permanent four-wheel drive. The 2.5 V6 TDI high-end model was unveiled with 180 PS and standard Quattro. Halfway through 2001 the Avant was unveiled.
Audi upgraded power to the 1.8 Turbo engine for 2002 to163 and 190 PS. The 190 was designated by a red T with both available with Quattro and in the 2.5 TDI intermediate version to 163 PS. Fuel Stratified Injection was also available with a 2.0 engine. The S4 was reintroduced the following year and was now powered by a 344 PS 4.2 LV8 engine. An A4 Cabriolet convertible variant was also introduced and finally replaced the 80-based Audi Cabriolet that had been discontinued in 1998. The variant included an electro-hydraulic operated hood which could be lowered in less than 30 seconds and also incorporated some styling changes which found their way to the saloon version.
Generally regarded as being the best of its type in the entire world, a continuously variable transmission was developed by LuK, named multitronic which was the replacement of the Tiptronic on front-wheel drive models. This transmission was well praised due to its light weight and promptness in response. The use of this transmission was limited to models with a maximum of 229 lb/ft of torque.
The trunk was redesigned to remove the extension of the top edge with a smoother fold line, and the taillight assembly now forms part of the top line. Introduced in the North American market, an 'Ultra Sport package' named Ultra Sport came along shortly before the B6 was replaced by the B7. This package included aluminum interior trim and doors sills, front and rear spoilers, 'S line' steering wheel, side valence and 18-inch RS4 wheels.
In 2004 Audi introduced a very largely revised A4 with the internal designation of B7. The new range A4 continued to utilize the already existing Volkswagen B6 platform, a chassis derived from the outgoing B6, but featuring heavily revised steering settings, new engine ranges, suspension geometry, navigation systems and chassis electronics. The internal platform nomenclature used PL46 for both B6 and B7 chassis. Also unchanged from the B6 A4 were the Typ 8E and 8H internal designations.
Many additions were added to the engine lineup. FSI, or Fuel Stratified Injection was introduced in 2005 on the 2.0 TFSI and 3.2 V6 FSI petrol/gasoline engines along with other refinements, and increased power output to 200 and 255 PS. Both engines utilize a four-valve cylinder design. The earlier 5-valve design was not compatible with the FSI direct injection system. Combining Pumpe Düse, or PD, technology, the 2.0 TDI diesel engine with 16 valves for the first time, and the larger 2.5 TDI was increased to 3.0 L offering 204 PS Quattro permanent four-wheel drive remained available on most A4 models. The 5-speed manual transmission was finally deleted in favor of a 6-speed. Once again, multitronic transmission is available on front-wheel drive models. A 6-speed Tiptronic transmission is available on Quattro four-wheel drive models.
Audi reintroduced the ultra-high performance RS4 to the lineup, in addition to the higher-performance S4 which carried over the powertrain of the B6 S4. This was the first time on the saloon/sedan and Cabriolet body with a normally aspirated 4.2 V8 FSI engine. The 3rd generation Torsen T-3 quattro system used a ‘default' asymmetric 40:60 front-rear torque distribution.
Introduced in late 2005, a limited edition variant was dubbed 'DTM Edition' and was reintroduced in 2006 as a regular option. The 2.0T FSI engine was now engineered to 220 PS wit standard Quattro. In the same manner of the C6 Audi A6, the front grill assembly has changed to be a tall trapezoidal shape. Arriving later than the other two body variants, the B7 Cabriolet model was introduced. Sales began in February of 2006. The Cabriolet featured an entry-level 2.0 TDI version.
Offering many safety features, the Audi A4 featured side airbags, anti-lock brakes, Electronic Stabilization Programme and its available Quattro four-wheel drive. The Audi A4 also received the IIHS 'Top Safety Pick For 2007'. The A4 Avant with the diesel engine is considered to be the most reliable vehicle available on the market according to 2007 Swedish vehicle inspection data, with vehicle inspection rejection rate of 0.0% in 3 year old category. Face-lifted and rebadged, the B7 series became the SEAT Exeo in 2008 with styling changes to both the front and rear, and also incorporated interior trim from the A4 Cabriolet.
In August of 2007, Audi introduced photos, the first official photos of the B8 series A4. The vehicle was unveiled to the public at the September 2007 Frankfurt Motor Show. Available models were the Saloon/Sedan and the Avant (estate/wagon). The Avant debuted at the March 2008 Geneva Auto Show.
Built on a variant of the Audi Modular Longitudinal Platform, the B8 A4 was constructed on a platform which was also utilized in the Audi A5 coupe. Earlier A4 chassis were limited in wheelbase because of the relationship between the engine, front axle and transmission, and the MLP allows for a reduced front overhang. This resulted in a greater wheelbase length without he same increase in overall length. The center of gravity is now effectively redistributed rearwards, which now improved handling by effectively balancing vehicle mass in between the front and rear axles. The front:rear weight ratio of B8 A4 is approximately 55:45 depending on the body style and engine. Handling was also improved over earlier A4 platforms due to the relocation of the steering rack in front of the axle.
The length of the B8 A4 was also increased in length by 117 mm (4.6 in) over the earlier Audi B7 and gave room for additional seating legroom. The curb weight dropped around 10%, the trunk was increased to 17 cu ft. for the saloon version. With the rear seats folded down, the A4 Avant has a maximum capacity of 1,430 liters. Introduced in the China market in November 2008 was a long wheelbase version called the A4L. This model came with a 2.4 inch longer wheelbase and 2.0 inch longer length.
Standard on the A4 was the MMI system; Multi Media Interface, electronic park brake, LED daytime running lights and speed sensitive steering. Optional on the Audi A4 was Audi Side Assist, Audi Lane Assist, Advanced Key; keyless entry and start, adaptive cruise control, Bang & Olufsen sound system, navigation system with full MMI with 7 inch screen, adaptive headlights with cornering technology, Audi drive select and advanced parking system front and rear plus reversing camera.
In 2004, the Audi Sport A4 DTM was introduced and was entered into the Deutsche Tourenwagen Masters series. The DTM was a V8 engined silhouette racing car that resembled the A4. These vehicles are identified by Audi Sport R-series designations.
Today buyers can purchase an Audi A4 in convertible, sedan and wagon configurations. The wagon and A4 sedan are in their fourth generation which began in the 2009 model year. The newest A4 sedans and wagons feature more interior room, more high-tech gadgetry and improved driving dynamics. Since convertible A4's have not yet been produced on the four-generation current platform, the Audi continues to be sold in 3rd generation models.By Jessica Donaldson
