Audi A4

The first generation Audi A4 debuted in 1994. It was built on the Volkswagen Group B5 platform, which it shared with the fourth generation Volkswagen Passat. 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 sedan.

The Audi A4 was the first model in the Volkswagen Group to feature the new 1.8 liter 20v engine with five valves per cylinder, based on the unit Audi Sport had developed for their Supertouring race car. A turbocharged version produced 148 bhp and 210 newton meters (155 lb·ft) torque. This technology was added to the V6 family of engines in 1996, starting with the 2.8 liter V6 30v, which now produced190 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.
