Background
Audi’s first car to wear the S4 badge was, in fact, based on the Audi 100 (C4) model and was introduced in 1992. As has become the fashion with first edition Audis, this is now often known as the “Ur-S4” based on the German word for original – Ursprünglich.
The model featured here is the second generation S4 based on the B5 platform and was launched in 1997. Although a physically more compact model than its predecessor, the new S4 was a technical tour-de-force and became Audi’s fastest saloon at the time of its launch. The B5 car boasted a 2.7L, twin-turbo V6 engine with five valves per cylinder. This powerplant matched with the standard six-speed manual gearbox and Torsen T-1 quattro permanent four-wheel drive system, made for a consummate drivers’ car.
The headline figures were impressive and highly competitive for the time. The 0-60mph sprint was reported to be dispatched in 5.6 seconds and the top speed was an electronically limited 155 mph. On the road, however, it was the V6’s torque curve that defined the driving experience. The full 258 Ib-ft of torque was available from 1,800 rpm to 4,000 rpm. This makes the car admirably tractable meaning that the 01E C90 six-speed box doesn’t require constant stirring to exploit the full potential of this ultimate Q-car.
