Audi A4

The Audi A4 is a compact executive car produced by the German automaker Audi since 1994. The first generation A4 succeeded the Audi 80.

It is available as a saloon/sedan or a estate/wagon (Audi calls it the "Avant"). The 2nd (B6) and 3rd generations (B7) of the A4 also had a Cabriolet version, which was not retained for the 4th generation (B8), due to the introduction of the related A5 coupé/cabriolet.

B5 (Typ 8D, 1994–2001)

The first-generation Audi A4 (known internally as the Typ 8D) was debuted by Audi in 1994 on the Volkswagen B5 platform, which it shared with the fourth generation Volkswagen Passat. It had a longitudinal engine and standard front-wheel drive, although many of the A4 owners selected the optional 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 2.8litres, and a 1.9L Diesel available with VW's new "Pumpe Düse" (PD, or unit injector) technology, capable of achieving a then high power value of 110PS (81kW), although Audi's 2.8L 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 1.8L 20V motor with five valves per cylinder, based on the unit Audi Sport had developed for their Supertouring race car. A turbocharged version produced 150PS (110kW) and 210Nm (155ft·lbf.) of torque. This technology was added to the V6 family in 1996, starting with the 2.8L V6 30V, which now produced 193PS (142kW).

Audi also debuted their new Tiptronic 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.
