Audi A4

The A4 has been built in four generations and is based on Volkswagen’s B platform. The first generation A4 succeeded the Audi 80. The automaker’s internal numbering treats the A4 as a continuation of the Audi 80 lineage, with the initial A4 designated as the B5-series, followed by the B6, B7, and the current B8. The B8 A4 is built on the Volkswagen Group MLB platform shared with many other Audi models and potentially one Porsche model within Volkswagen Group. [ 2 ]

The first generation Audi A4 (known internally as the Typ 8D ) debuted in October 1994, [ 4 ] [ 5 ] with production starting November 1994 and European sales commencing in January 1995 for the 1995 model year. North American sales later began in September 1995 for the 1996 model year. [ 6 ] It was built on the Volkswagen Group B5 (PL45) platform. which it shared with the fourth generation Volkswagen Passat (B5, Typ 3B). It had a front-mounted longitudinal engine and front-wheel drive.

Many variations of the A4 were also available with Audi’s quattro four-wheel drive system. The A4 was initially introduced as a four-door saloon/sedan ; the Avant (estate/wagon ) was introduced in November 1995 and went on sale in February 1996.

Development began in 1988, with the first design sketches being created later that year. By 1991, an exterior design by Imre Hasanic was chosen and frozen for November 1994 production by 1992. The interior design was later finalized in 1992, with pilot production commencing in the first half of 1994. Development concluded in the third quarter of 1994, preceding November 1994 start of production. [ 7 ] [ 8 ] [ 9 ] [ 10 ]

A wide range of internal combustion engines were available in European markets, between 1.6 and 2.8#160;litres for petrol engines ; and a 1.9#160;litre diesel engine available with Volkswagen Group ‘s VE technology, capable of achieving a 90#160;PS (66#160;kW ; 89#160;bhp ) or 110#160;PS (81#160;kW; 108#160;bhp), although Audi’s 2.8#160;litre V6 engine. 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#160;litre 20v engine with five valves per cylinder. based on the unit Audi Sport had developed for their Supertouring race car. A turbocharged version produced 150#160;PS (110#160;kW; 148#160;bhp) and 210 newton metres (155#160;lb·ft ) torque. This technology was added to the V6 family of engines in 1996, starting with the 2.8#160;litre V6 30v, which now produced 193#160;PS (142#160;kW; 190#160;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 offering the driver fully automatic operation or manual selection of the gear ratios.

B5 facelift (1997–2001) [ edit ]

Audi A4

A refreshed B5 A4 range appeared at the 1997 Frankfurt Motor Show. with sales beginning in Europe in early 1998. The 2.8#160;litre 30-valve V6 engine replaced the 2.8#160;litre 12-valve. A 2.5#160;litre V6 Turbocharged Direct Injection (TDI) diesel engine with 150#160;PS (110#160;kW ; 148#160;bhp ) was standard on the quattro.

A six-speed manual gearbox was available, as well as the new high-performance Audi S4. now part of the A4 lineup (the previous S4 had been an Audi 100 ). Cosmetic updates included new rear lights, headlights. door handles, and other minor exterior/interior changes.

In mid-1998, the 1.8 20vT engine available outside Europe had its power output raised to 170#160;PS (125#160;kW; 168#160;bhp). The previous KKK K03 turbocharger. although fundamentally unchanged, received revisions on the turbine side to prevent cracking due to heat. [ citation needed ] The 12-valve V6 was replaced by the 30-valve unit which had been available in Europe for two years.

A further facelift took place across the A4 and S4 platform in February 1999 as a 1995.5 model; changes were largely cosmetic, but affected many components, such as both front and rear bumpers, the front and rear lights, the center console, and door handles. [ 11 ]

In 1999 Audi also debuted an even higher performance R enn S port model, the RS4 Avant. like its predecessor RS2. available only in the Avant bodystyle.
