The 2011 Audi A4, A4 Avant and S4
The 2011 Audi A4 is the benchmark of the mid-sized sedan segment as well as the largest selling vehicle in the Audi lineup. With an array of fuelefficient and powerful engines – including the 333 hp 3.0 TFSI® V6 in the S4 – the A4 has the flexibility and power that environmentally concerned buyers also demand. With a full complement of suspension and engine technology derived directly from Audi's expertise in racing, the 2011 Audi A4 presents an image that exudes performance, efficiency and luxury.The Design | Bold lines, distinguished styling
With a progressive exterior and a purposeful style, the 2011 Audi A4 maintains its presence as a leader in automotive design. A taut musculature denoted by strong shoulders and a dramatically raked roofline has become synonymous with the Audi name, and the A4 showcases both of these traits. Innovations like LED accent lighting and a bold Singleframe® grille now are instantly recognizable by both the public and the competition.The Interior | Style, intuitive ergonomics, and Audi technology
With an interior designed to be spacious and inviting, the Audi A4 is driver oriented, while also catering to passengers. From the driver's seat, it is apparent immediately that the Audi A4 shares DNA with the luxurious A8. The cockpit incorporates a center stack tilted slightly toward the pilot, and brilliant, easy-to-read gauges hint of an athletic nature.
The long-standing Audi commitment to craftsmanship and quality materials is obvious in the 2011 Audi A4. Supportive seats are executed in high-quality leather, while brushed accents throughout the cabin draw the eye from one flowing surface to the next. With three interior colors from which to choose, buyers are guaranteed an interior choice designed to please the individual palette.
The 2011 Audi A4 offers an unparalleled array of cutting edge technology to make the driving experience safer and more relaxed. The available Audi parking system with rear backup camera, standard for 2011 on the Prestige trim level, makes getting in and out of tight spaces easier than ever. Audi side assist alerts the driver to blind spot dangers, while adaptive cruise control automatically accelerates or decelerates to keep pace with traffic.
A host of entertainment options makes the Audi A4 perfectly suited for individuals who demand the most from their vehicles. The available Audi music interface ensures seamless iPod® integration – channeling buyers' favorite music through an unrivalled 505-watt 14-speaker Bang & Olufsen® Sound System. Further enhancing the entertainment experience, available state-ofthe- art hard drive based navigation with third generation MMI® system now includes HD Radio™ for 2011.
The A4 continues to offer buyers more interior space than any of its direct competitors. Occupants are treated to expansive legroom, thanks in part to the A4's overall length of 15.4 feet. Buyers also can take advantage of the 60/40 folding rear seats to transport even larger baggage, including skis and snowboards. Despite the generous interior space, the A4 remains light on its feet thanks to an ever-present focus on lightweight, rigid body construction.
Going further, the A4 Avant offers an even greater level of utility and convenience, with a remarkable 17.3 cubic feet of cargo space – a figure that is unmatched by the competition. The cargo area is completely lined with carpeting that is especially durable and stain resistant. Four lashing eyes in the floor are standard, as are two chrome hooks on the sides that can be adjusted to secure the bulkiest baggage. Buyers also can opt for the convenience of a power tailgate, which comes standard on Prestige trim level models.

The Engines | Powerful, responsive and efficient
In the A4, each powerplant benefits from direct-injection technology to increase efficiency and response. The 2.0 TFSI turbocharged inline four and the 3.0 TFSI supercharged V6 both take advantage of forced induction to increase horsepower and torque without the penalty of added fuel consumption.
The 2.0 TFSI delivers an impressive 211 hp and 258 lb-ft of torque, thanks to Audi's innovative direct-injection fuel system. Gasoline is injected into the engine's combustion chambers at the high pressure of 2,175 psi, which ensures a fine spray pattern for a more efficient burn. The seamless power delivery of the water-cooled turbocharger allows the 2.0 TFSI to develop peak torque from just 1,500 rpm. The result is a driving experience that rewards buyers with an instant
rush of power at nearly any engine speed.
The 2011 Audi S4 is powered by an all-aluminum 3.0 TFSI supercharged V6 engine with 333 hp and 325 lb-ft of torque. Despite these remarkable figures, the S4 is able to achieve 28 mpg on the highway, a remarkable 27 percent improvement over the previous generation S4. With an immediately responsive drive-by-wire throttle system, the 3.0 TFSI offers an instant connection from driver input to a resulting surge of acceleration.Drivetrains | More choices and more gears for every driver
The 2011 Audi A4 is available with the buyer's choice of three transmissions. A multitronic® continuously variable transmission is available on the A4 FrontTrak,® while quattro® equipped vehicles can be optioned with either a six-speed manual gearbox or an all-new for 2011 Tiptronic® eight-speed automatic transmission. (posted on conceptcarz.com)
More than a standard automatic transmission, Tiptronic allows the driver to select the ideal gear manually, with nearly imperceptible shifts. An additional Sport mode maintains engine speed longer to make the most out of each engine's
The 2011 S4 is available with a six-speed manual or the brilliant Audi seven-speed S tronic® dual-clutch transmission, which allows the driver to enjoy power from the 3.0 TFSI supercharged V6 in nearly uninterrupted bursts – providing the perfect marriage of speed and comfort. The system works using dual clutches and twin input shafts, thereby allowing the computer to 'predict' which gear the driver intends to use and prep the gear for action before it is selected.
Also available on the S4 is quattro with Sport rear differential, which gives the S4 a new level of road holding ability, by actively controlling the distribution of torque between the two rear wheels, effectively overdriving the outside wheel in corners. This 'forces' the front end of the vehicle into the corner, thus eliminating understeer and creating more attainable excitement for the driver. In addition, the Sport rear differential works with ESP® during accident avoidance maneuvers to keep the S4 stable and composed in emergencies.Suspension | The source of control
While the smooth ride quality and athletic driving feel of the 2011 Audi A4 are enhanced by an incredibly rigid body design and the extensive use of lightweight materials, the advanced suspension is the real star of the show. The Audi A4 2.0T comes standard with an advanced five-link front suspension with upper and lower control arms and anti-roll bar. In the rear, an independent trapezoidal suspension with anti-roll bar helps provide the world-class handling characteristics that buyers have come to associate with the Audi brand. Each individual link is crafted from high-quality aluminum to reduce weight at each wheel, and a strong cross member is made of the same metal to enhance rigidity without sacrificing the Audi A4's lightweight
The 2011 Audi A4 offers extremely precise steering, thanks in part to a steering box located lower and further forward than on other comparable models. The effect is noticeable immediately, giving the Audi A4 a light and agile dimension. The innovative engineering combines with Audi dynamic steering to vary the ratio depending on vehicle speed. This equates to a more balanced system that offers quicker lock-to-lock feedback at low speeds and stable cornering when the vehicle is traveling fasterÚncompromising Safety | The ultimate protection
Safety, as central to the Audi brand as its multiple Le Mans victories, is evident in the 2011 Audi A4, which features a number of advanced technologies designed to keep occupants out of harm's way. The A4's rigid body is built of ultra-high strength steel, using state-of-the-industry manufacturing processes. With components joined by traditional spot welding as well as new structural bonding techniques, the A4 has a body structure designed to absorb and deflect crash energy away from occupants.
Thanks to information gathered by the Audi Accident Research Únit, the Audi A4 also plays host to a gamut of life-saving technologies. For example, the steering column can deform toward the front of the car by more than three inches to protect the driver. An array of sensors detects exactly how far the front seats are from the dashboard, allowing the Audi A4 to tension seatbelts actively to prevent occupants from injury when air bags inflate. Adjustable headrests also provide ample whiplash protection in the event of a rear collision.
The 2011 Audi A4 incorporates seat-mounted side-impact air bags, front air bags for the passenger and driver, and expansive side-curtain air bags. Onboard air bag sensors can detect the severity of a crash and inflate accordingly. The result is a lower injury rate from airbag

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
