and replace the famous Audi Quattro (launched in 1980). It featured the well-proven 2.2-litre in-line five-cylinder 20-valve turbo petrol engine from the Audi 200 20V, which was a variant of the engine used in the Audi Quattro. A similar version of the engine was used in the Audi 100 based S4 (the 'Ur-S4'). The S2 came as standard with quattro permanent four-wheel drive, and featured a heavy-duty 5-speed manual transmission, and was capable of 150 mph. The S2 was initially available with a 2.2-litre turbocharged engine which produced (Engine code 3B), coupled to a 5-speed transmission. In 1992, the engine received minor upgrades, including distributor-less ignition, which increased power output to (Engine code: ABY) which was coupled to a new 6-speed gearbox. Although the power increase was minimal, the engine now produced of torque (up from ) and featured an overboost function that allowed up to in short bursts. The 3B-engined car will accelerate from 0- in 5.7 seconds, continuing to a top speed of . The ABY-engined S2 Coupé will accelerate from 0- in 5.9 seconds, continuing to a top speed of . In 1993, the S2 received some cosmetic updates, including new AVUS-style alloy wheels, ellipsoid beam (projector) headlamps and clear front indicator lenses.

These models came standard with 15" 6-star "Speedline" wheels, leather interiors with Zebrano wood trim, additional VDO gauges mounted in the bottom of the centre console, a carbon fibre centre prop shaft, and push-button locking rear differential. The Coupé quattro is visually similar to the European-only S2 model, but does not have the S2's turbocharged engine. It was only sold for two model years in the United States, 1990 and 1991. Cabriolet The Audi Cabriolet (Typ 8G) based on the B3 Coupé, was introduced in May 1991.
