The Audi A4 is a compact executive car produced by the German automaker Audi AG since late 1994. The initial generation A4 succeeded the four previous generations of the Audi 80.

Since its inception, the Audi A4 has been available in four generations, based on the Volkswagen Group 'B' series of automobile platforms - usually known by the following codes - the initial B5, the subsequent B6 and B7, and the current B8.

Of the main body styles, it is (and has been) always available as a saloon/sedan variant, and an "Avant", which is Audi's name for an estate/wagon. The second (B6) and third generations (B7) of the A4 also had a Cabriolet version, but the Cabriolet was not retained for the current fourth generation (B8), due to the introduction of the Cabriolet version of the related Audi A5 and S5 coupés.

Additionally, higher performance versions directly related to the A4 include the Audi S4, and the limited availability very high performance Audi RS4.

Successor	Audi A4 (B6)

The first-generation Audi A4 (known internally as the Typ 8D) was debuted by Audi in 1994, with production starting November 1994. It was built on the Volkswagen Group B5 platform, which it shared with the fourth generation Volkswagen Passat (B5, Typ 3B). It had a front-mounted longitudinal engine and standard front-wheel drive, and many variations of the A4 were also available with Audis' 'trademark' quattro four-wheel drive system. The A4 was initially introduced as a four-door saloon/sedan; the Avant (estate/wagon) arrived a year later.

A wide range of engines were available to European customers, between 1.6 and 2.8 litres for petrol engines, and a 1.9 L diesel engine available with Volkswagen Group's VE technology, capable of achieving a 90 PS (66 kW; 89 bhp) or 110 PS (81 kW; 108 bhp), although Audi's 2.8 L V6, carried over from the old 80/90 was the only engine option in North America until 1997.

The Audi A4 was the first model in the Volkswagen Group to feature the new 1.8 L 20v motor with five valves per cylinder, based on the unit Audi Sport had developed for their Supertouring race car. A turbocharged version produced 150 PS (110 kW; 148 bhp) and 210 newton-metres (155 lbf⋅ft) torque. This technology was added to the V6 family of engines in 1996, starting with the 2.8 L V6 30V, which now produced 193 PS (142 kW; 190 bhp).

Audi also debuted their new tiptronic automatic transmission on the B5 platform, based on the unit Porsche developed for their 964-generation 911. The transmission is a conventional automatic gearbox with a torque converter, but it offers the driver a choice of driving the car as either a fully automatic operation, or with a manual override of the gear ratios.

1998-2001 Audi A4 Avant

A refreshed B5 A4 range appeared at the 1997 Frankfurt Motor Show, with sales beginning in Europe in early 1998. Besides the introduction of a 2.8 L 30-valve V6 engine (replacing the 2.8 L 12-valve), the most important additions to the range were the 2.5 L V6 Turbocharged Direct Injection (TDI) diesel engine with 150 PS (110 kW; 148 bhp) and standard quattro, and a six-speed manual gearbox, as well the new high-performance Audi S4, now part of the A4 lineup (the previous S4 had been an Audi 100). New rear lights, headlights, door handles, and other minor exterior/interior changes rounded out the cosmetic updates.

In mid 1998, the 1.8 20vT engine available outside Europe had its power output raised to 170 PS (125 kW; 168 bhp). The previous KKK K03 turbocharger, although fundamentally unchanged, did receive some revisions on the turbine side to prevent cracking due to heat. The 12-valve V6 was replaced by the 30-valve unit which had been available in Europe for two years.

In 1999, Audi debuted an even higher performance RennSport model, the RS4 Avant, like its predecessor RS2, available only in the Avant bodystyle.

2005 A4 saloon S line (US)

An all-new A4, internally designated Typ 8E, debuted in late 2000, now riding on the all-new Volkswagen Group B6 (PL46) platform. The car's new styling was inspired on the C5 (second-generation) Audi A6. The 1.6 L base model remained unchanged, but most other petrol/gasoline engines received either displacement increases, or power upgrades. The 1.8 L 20-valve Turbo was now available in two additional versions, with 150 PS (110 kW; 148 bhp) or 180 PS (132 kW; 178 bhp), this one with a standard six-speed manual gearbox, while the naturally aspirated 1.8 L straight-4 and 2.8 L V6 were replaced by 2.0 L and all-aluminium alloy 3.0 L units, still with five valves per cylinder, the most powerful of which was capable of 220 PS (162 kW; 217 bhp) and 300 newton-metres (221 lbf⋅ft) of torque. The 1.9 Turbocharged Direct Injection (TDI) engine was upgraded to 130 PS (96 kW; 128 bhp), with Pumpe Düse (Unit Injector) (PD) technology, and was now available with quattro permanent four-wheel drive, while the 2.5 V6 TDI high-end model was introduced with 180 PS (132 kW; 178 bhp) and standard quattro. This generation of quattro consists of default of 50:50 front to rear dynamic torque distribution. A Bosch ESP 5.7 Electronic Stability Programme (ESP) system, with Anti-lock Braking System (ABS), brake assist, and Electronic Brakeforce Distribution (EBD) were standard across the range.

The Avant arrived in mid 2001.

For 2002, Audi upgraded power in the 1.8 Turbo engines to 163 PS (120 kW; 161 bhp) and 190 PS (140 kW; 187 bhp) - the 190 PS variant designated by a red 'T' on the boot lid, with both available with quattro, and in the 2.5 TDI intermediate version to 163 PS (120 kW; 161 bhp). A 2.0 engine with Fuel Stratified Injection (FSI) was also available. A year later, Audi reintroduced the S4, now powered by a 344 PS (253 kW; 339 bhp) 4.2 L V8 engine, as well as an A4 Cabriolet convertible variant (Typ 8H), finally replacing the 80-based Audi Cabriolet which had been discontinued in 1998. It included an electro-hydraulic operated hood, which lowered in under 30 seconds, and incorporated some styling changes which eventually found their way to the saloon version (such as body-colored lower bumper and sill panels).

Audi also introduced a continuously variable transmission developed by LuK, named multitronic, which replaced the conventional automatic transmission on front-wheel drive models. The transmission won considerable praise from the automotive press, and is generally regarded as being the best of its type in the world, due to its light weight and promptness in response, but its use was limited to models with a maximum of 310 N⋅m (230 lbf⋅ft) of torque.

Borrowing from the Audi A6, the boot was redesigned to remove the extension of the top edge with a smoother fold line, and the rear light assemblies now formed part of the top line.

An "ultra sport package" named 'Ultra Sport' was introduced in the North American market shortly before the B6 was replaced by the B7. It included aluminium interior trim and door sills, "S line" steering wheel, front and rear spoilers, side skirts, and quattro GmbH designed 18" RS4 alloy roadwheels.

Audi A4 DTM Edition

Audi introduced a heavily revised A4 in late 2004, with the internal designation of B7. However, this new range A4 still utilised the existing Volkswagen B6 (PL46) platform, a chassis derived from the outgoing B6, but enjoyed heavily revised steering settings, suspension geometry, new engine ranges, navigation systems and chassis electronics (including a new advanced Bosch ESP 8.0 Electronic Stability Programme (ESP) system). The front grille assembly has changed to be a tall trapezoidal shape in the same manner as the C6 (third-generation) Audi A6.

Audi's internal platform nomenclature uses PL46 (passenger car longitudinal platform, size 4, generation 6) for both B6 and B7 chassis. The Typ 8E and 8H internal designations are also carried over from the B6 A4 range, but now have an additional identifying suffix - 8EC for the saloon, 8ED for the Avant, and 8HE for the Cabriolet.

The engine lineup received many additions. The 2005 introduction of Fuel Stratified Injection (FSI) on the 2.0 TFSI and 3.2 V6 FSI petrol/gasoline engines, as well as other refinements, increased power output to 200 PS (147 kW; 197 bhp) and 255 PS (188 kW; 252 bhp), respectively. These engines both implement a four-valve per cylinder design. The prior 5-valve design was incompatible with the FSI direct injection system (due to the siting of the fuel injector, now discharging directly into the combustion chamber). The 2.0 Turbocharged Direct Injection (TDI) diesel engine now combines Pumpe Düse (Unit Injector) (PD) technology with 16 valves for the first time, while the larger 2.5 TDI V6 diesel was superceeded by a 3.0 V6 TDI, offering 233 PS (171 kW; 230 bhp). A 2.7 V6 TDI was added later.

Torsen T-2 based quattro permanent four-wheel drive remained available on most A4 models. Audi retired its 5-speed manual transmissions in favour of a new Getrag 6-speed. As before, multitronic continuously variable transmission (CVT) is available on front-wheel drive models, whilst a conventional ZF 6HP 6-speed tiptronic automatic transmission is available on the quattro four-wheel drive models.

In addition to the higher-performance Audi S4, which carried over the powertrain from the B6 S4 - Audi has reintroduced the ultra-high performance Audi RS4 (RS for RennSport) to the lineup, for the first time on the saloon/sedan and Cabriolet body, and with a normally aspirated, but high-revving 4.2 V8 FSI engine. Another notable inclusion on the RS4 is the latest generation Torsen T-3 quattro 4wd system, which uses a 'default' asymmetric 40:60 front-rear dynamic torque distribution bias. This new asymmetric centre differential was initially only available on the RS4, but was added a year later on the S4. The remainder of the B7 A4 range still utilised the T-2 50:50 default dynamic split centre diff.

A limited edition variant, developed by quattro GmbH, was first introduced in May 2005, named "Audi A4 DTM Edition". It was inspired from Audi's race cars of the 2004 Deutsche Tourenwagen Masters, and was reintroduced in 2006 as a regular option. The 2.0T FSI engine received revised software mapping to the ECU, which increased the output to 220 PS (162 kW; 217 bhp) and 300 N⋅m (221 lbf⋅ft) of torque. It was available with front-wheel drive, or quattro four-wheel drive.

The B7 Cabriolet model arrived later than the other two body variants, with sales beginning in February 2006. New on the Cabriolet was an entry-level 2.0 TDI version, but to date, this is not being offered with the multitronic CVT gearbox.

According to 2007 Swedish vehicle inspection data, the Audi A4 Avant with diesel engine is the most reliable vehicle available on the market, with vehicle inspection rejection rate of 0.0% in 3 year old category. (Please note that although the Mitsubishi Galant estate, Volkswagen Touareg and Toyota HiAce Traveller share the rejection rate of 0,0%, A4's result is achieved with average mileage of over 111,000 kilometres (69,000 mi), while the average mileage for other cars achieving the 0,0% rejection rate is between 71,000 km (44,000 mi) and 77,000 km (48,000 mi).)

When its successor, the new B8 A4 range was introduced, the B7 series A4 was restyled and rebadged as the SEAT Exeo in 2008, with styling changes to the front and rear, also incorporating interior trim from the A4 Cabriolet. The entire Audi B7 A4 production line from Ingolstadt was dismantled and sent to Volkswagen Group's related SEAT factory in Martorell, Spain.

B7 safety

The Audi A4 offers many standard safety features, including Bosch 8.0 Electronic Stability Programme (ESP) with Anti-lock Braking System (ABS), side airbags in the seats, 'sideguard' curtain airbags, and its optional quattro four-wheel drive system. It also received the Insurance Institute for Highway Safety (IIHS) "Top Safety Pick For 2007".

Audi B8 A4 Avant

LED daytime running lights of A4

Audi released the first official pictures of the B8 series A4 in August 2007, and unveiled the car to the public at the September 2007 Frankfurt Motor Show. Saloon/sedan and Avant (estate/wagon) models are offered. The Avant was unveiled to the public at the March 2008 Geneva Motor Show.

The B8 A4 is built on a variant of the Audi Modular Longitudinal Platform, a platform which is also used in the Audi A5 coupé. Whilst prior A4 chassis were limited in wheelbase due to the relationship between the engine, transmission and front axle, the MLP allows for a reduced front overhang, resulting in a greater wheelbase length without the same increase in overall length. This effectively redistributes the centre of gravity slightly rearwards, improving handling by better balancing vehicle mass between the front and rear axles. The estimated static front:rear weight ratio of the B8 A4 is approximately 55:45, depending on body style and engine. The relocation of the steering rack in front of the axle also improves handling over previous A4 platforms.

The B8 A4 has increased in length by 117 millimetres (4.6 in) over the prior B7, which has allowed for increased rear seating legroom. Although the overall dimensions have increased, the kerb weight has dropped some 10%. The boot (trunk) has also increased to 480 litres (17 cu ft) for the saloon (sedan) version. The A4 Avant will have a maximum capacity of 1,430 litres with the rear seats folded down.

All variants of the engines offered on the B8 are now standardised to utilise Volkswagen Group's latest technology. All petrol engines use Fuel Stratified Injection (FSI), and all diesel engines use the common rail (with a pressure of 1,600 bars (160,000 kPa)) fuel delivery, with piezo injectors of their Turbocharged Direct Injection engines.

A long wheelbase version called the A4L was launched for the China market in November 2008 with a 60 mm (2.4 in) longer wheelbase and 50 mm (2.0 in) longer length.

In 2009, Audi announced the 7-speed dual-clutch S tronic transmission as option for A4 in UK and European markets.

The A4-based convertible model will not return. It is scheduled to be replaced by the A5/S5 Cabriolet.

B8 specifications

The luggage capacity measurements, measured using the VDA test method for the saloon are: 480 litres (17.0 cu ft) with the rear seats in the upright position, and 962 L (34.0 cu ft) with the seats folded flat. For the Avant: 490 L (17.3 cu ft) with the rear seats upright, and 1,430 L (50.5 cu ft) with the seats folded.

Kerb (curb) weight of the saloon variant ranges from 1,410 kilograms (3,109 lb) to 1,690 kg (3,726 lb), and for the Avant from 1,470 kg (3,241 lb) to 1,695 kg (3,737 lb) (all dependent on specification).

The 3.0 TDI V6 diesel engine is only available with the quattro permanent four-wheel drive system (which is also optional on the lesser engines); now using the latest Torsen T-3 centre differential, with a default 40:60 front to rear asymmetric torque distribution ratio (used first on the B7 RS4) as standard. (Previous A4 quattro models split torque with a default front:rear 50:50). The additional torque bias applied to the rear wheels helps mimic the driving dynamics of rear wheel drive cars.

B8 equipment

Standard equipment on the B8 A4 includes:

• LED daytime running lights (on some models);
• MMI system (Multi Media Interface) (multi-mode interface of driver information and entertainment systems); (3rd generation MMI expected in vehicles produced from week 22 of 2009)
• Electronic hand brake

B8 A4 allroad quattro

An allroad variant of the A4 Avant, similar to the Audi A6 allroad quattro, was announced by Audi in February 2009. The A4 allroad quattro features a wider track, increased ground clearance, quattro permanent four-wheel drive, a distinctive radiator grille, stainless steel underbody guards and roof rails. It is expected to be available in the early summer of 2009.

The car was unveiled in 2009 Geneva Motor Show.

B8 A4 TDI concept e

In 2008, Audi announced a fuel-efficient A4 concept car, called the Audi A4 TDI concept e. It includes a common rail 2.0 TDI diesel engine (1,968 cc (120.1 cu in)) rated at 88 kW (120 PS; 118 bhp) and 290 N⋅m (213.9 lbf⋅ft), a stop-start system and regenerative braking. It can achieve a fuel consumption of 3.99L/100 km and CO₂ output of 105 g/km. It performs the standard discipline of 0-100 km/h (62.1 mph) in 10.7 seconds, and can reach a top speed of 206 km/h (128.0 mph)

This improvement in efficiency is achieved from a number of areas of re-engineering; the notable feature being the deletion of the engine-driven hydraulic power steering pump, and relying on an electric motor to provide the assistance. Other features include revised aerodynamics, low-rolling resistance 225/45 R17 tyres, and electric actuation of the rear brakes.

The car was unveiled in Paris Motor Show.

Audi Sport A4 DTM

Audi Sport re-entered the Deutsche Tourenwagen Masters (DTM) series in 2004 (after having privateer teams run the Abt Sportsline Audi TT-R) with a V8 engined silhouette racing car resembling the A4 saloon, known as the Audi A4 DTM.

In the past, Audi had used a V8 engine in the series with the original Audi V8 quattro, but had opted for a highly tuned V8 which Audi had no resources for. So Honda was contacted; at the time they had been using V8s in the Indy Racing League (IRL). Audi wanted a similar package in performance and reliability, so Honda and Mugen (M-Tec) got together and decided to let Audi use the Mugen/Honda MF308 V8 engine. The only improvements made to the racing engine by Audi was shaving weight off the crankshaft, since the engine had already been designed from the ground up. Audi Sport prepped tested/implemented/approved and raced the engine in 2004, which produced 460 bhp (343 kW; 466 PS) and over 500 N⋅m (370 ft⋅lbf) of torque in 4.0 litre trim, and has been a mainstay in Audi's DTM programme.

A4 DTM cars are identified by Audi Sport "R"-prefix designations. The following variants have been produced:

R11 (2004)

The Audi R11 A4 DTM car resembled the B6 bodystyle of the Audi A4.

R12 (2005-2006)

The Audi R12 A4 DTM car resembled the 2005 B7 bodystyle of the Audi A4. The R12 was revised for the 2006 season as the R12+.

R13 (2007)

The Audi R13 A4 DTM car also resembled the B7 bodystyle of the Audi A4.
