The Audi Sport Quattro S1 was introduced at the end of 1984 as an update to the Audi Sport Quattro. The car featured a inline 5-cylinder engine that displaced 2,110 cc (128.8 cu in) and produced an officialy quoted figure of 350 kW (480 PS/470 bhp).

However, the turbocharger utilised a recirculating air system, with the aim of keeping the turbo spinning at high speed, and the actual figure was in excess of 500 bhp (373 kW/507 PS) at 8000 rpm. In addition to the improved power output, an aggressive aerodynamic kit was added that featured very distinctive wings and spoilers to the front and rear of the car to increase downforce.

The weight was lightened to just 1,090 kg , and now accelerate from 0-100 km/h (62 mph) in just 3.1 seconds.

Some of the cars were supplied with a “power-shift gearbox”, which is said to be a forerunner of today’s Direct-Shift Gearbox technology.

The S1 proved to be an immediate success in the rally circuit, helping Walter Röhrl and Christian Geistdörfer win the 1985 San Remo Rally. A modified version of the S1, was also driven by Michèle Mouton. The S1 evolution would become the final Group B car produced by Audi, with the works team withdrawing from the Championship following the 1986 rally in Portugal.

Twenty years after the cancellation of Group B, the Sport Quattro S1 was still widely regarded as the most powerful rally car ever fielded in international competition, with the final factory machines of 1986 rated at an incredible 441 kW.

The Audi Coupe GT was a 2-door sports car produced and sold by Audi from 1981 to 1987. The Coupe GT was an attempt by Audi to offer a more affordable version of its turbocharged, all-wheel drive Quattro.

The Audi Coupe GT featured a similar body shape to the Quattro, but without the knife-edged fender flares of the more expensive car.

The Audi Coupe range was fitted with the quattro All Wheel Drive system from late 1984 to produce the Audi Coupe quattro, a model which was rarer than the Turbocharged Quattro model.
