The Audi S2 Coupe, specifically the 2.2i Turbo 20V quattro variant produced between 1990 and 1992, represents a pivotal moment in Audi’s performance lineage. Built upon the Audi 80 (B3) platform – internally designated as the B3 – the S2 was conceived as a homologation special for Group A rally racing, though its racing aspirations were ultimately curtailed by changes in the regulations. This coupe offered a significant performance upgrade over the standard 80, establishing a template for Audi’s future “S” models. The S2 Coupe served as a bridge between the more attainable Audi 80 and the flagship Audi Quattro, offering a compelling blend of performance, practicality, and understated luxury.

Powertrain & Engine Architecture
The heart of the S2 Coupe is the 3B engine, a 2.2-liter inline-five cylinder powerplant. This engine is a derivative of the unit used in the Audi Quattro, but significantly revised with a larger turbocharger and an improved intercooler. The 20-valve cylinder head (hence the “20V” designation) features dual overhead camshafts and four valves per cylinder, optimizing airflow for increased power output. Fuel delivery is managed by a Bosch Motronic multi-port fuel injection system, carefully calibrated to work in conjunction with the turbocharger. The engine produces 220 horsepower at 5900 rpm and 309 Nm (227.91 lb-ft) of torque at a remarkably low 1950 rpm. The engine’s longitudinal layout and the quattro all-wheel-drive system contribute to excellent traction and balanced handling. The standard transmission for the S2 Coupe was a robust five-speed manual gearbox, designed to handle the engine’s substantial torque.
Driving Characteristics
The S2 Coupe delivers a driving experience that is both engaging and refined. The turbocharger provides a noticeable surge of power, but it’s relatively linear and predictable, avoiding the abruptness sometimes associated with turbocharged engines. The quattro all-wheel-drive system provides exceptional grip, particularly in adverse weather conditions, inspiring confidence in cornering. The five-speed manual transmission offers precise shifts, and the gear ratios are well-matched to the engine’s powerband. While not a lightweight car, the S2 feels agile and responsive, thanks to its well-tuned suspension and balanced chassis. Compared to the standard Audi 80, the S2 offers a significantly more potent acceleration – 0 to 60 mph in around 5.8 seconds – and a higher top speed of 154.1 mph.
Equipment & Trim Levels
The S2 Coupe was relatively well-equipped for its time. Standard features included power windows, central locking, and an upgraded audio system. The interior typically featured sport seats upholstered in a combination of cloth and leather. Optional extras included a sunroof, heated front seats, and a more sophisticated audio system. The dashboard layout was similar to that of the standard Audi 80, but with unique S2 badging and instrumentation. The overall interior ambiance was one of understated luxury, reflecting Audi’s commitment to quality and refinement.
Chassis & Braking
The S2 Coupe’s chassis benefited from several upgrades compared to the standard Audi 80. The suspension was stiffened and lowered, improving handling and reducing body roll. The front suspension utilized independent coil springs, while the rear suspension also featured independent coil springs. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. An Anti-lock Braking System (ABS) was standard, enhancing safety and control. The S2 Coupe’s chassis was designed to handle the increased power and performance of the 2.2-liter turbo engine, delivering a confident and stable driving experience.
Market Reception & Comparison
The Audi S2 Coupe was generally well-received by automotive critics, who praised its performance, handling, and build quality. It was seen as a compelling alternative to other performance coupes of the era, such as the BMW 8 Series and the Porsche 944. Compared to other variants of the Audi 80, the S2 offered a significant performance advantage. While the standard 80 focused on practicality and fuel efficiency, the S2 prioritized driving enjoyment. The S2’s fuel economy was understandably lower than that of the standard 80, but it was still reasonable for a high-performance coupe. Reliability was generally good, although the turbocharger and associated components required regular maintenance.
Legacy
The Audi S2 Coupe holds a significant place in Audi’s history as the progenitor of the “S” model line. It demonstrated Audi’s ability to create high-performance cars that were both capable and refined. Today, the S2 Coupe is a sought-after classic car, particularly among Audi enthusiasts. Well-maintained examples are becoming increasingly rare and valuable. The 3B engine, while requiring careful maintenance, is known for its durability and potential for modification. The S2 Coupe remains a testament to Audi’s engineering prowess and its commitment to building exciting and engaging automobiles.
