The Audi S2 translated the original quattro’s five-cylinder, turbocharged, all-wheel-drive formula into a faster and more mature 1990s road car. Launched as a coupé in 1990, then joined by saloon and Avant derivatives, it also introduced the red S badge that became Audi’s shorthand for discreet high performance.
From quattro to S2
The S2 used the aerodynamic Audi Coupé and B4 Audi 80 family rather than directly continuing the box-arched Ur-quattro body. It retained the important ingredients: a turbocharged inline-five, permanent quattro drive and compact dimensions. The presentation was subtler, pointing towards the restrained S-car identity Audi still uses.
3B and ABY engines
Early Coupés used the 2.2-litre 20-valve 3B engine, rated at 220PS and paired with a five-speed gearbox. The later ABY developed 230PS, brought an overboost torque increase and was normally combined with a six-speed transmission. Engine code, gearbox and model year therefore matter when comparing cars.
Coupé, Avant and saloon
The Coupé is the version most people picture, but the S2 Avant became especially influential because it joined serious performance to an estate body. Audi also built a much rarer four-door S2 saloon. Together they showed that the S formula could work across body styles rather than belonging to one halo coupé.

How the S2 drives
The S2 is defined by traction, high-speed stability and a muscular surge once the turbocharger is working. It is heavier and more refined than an early quattro, with less of the older car’s rawness. That makes it an effective long-distance performance car, particularly in poor weather.
Its place between quattro and RS2
The S2 should not be reduced to a stepping stone. It established Audi’s S badge and modernised the five-cylinder quattro idea. Yet its S2 Avant platform also became the starting point for the Porsche-developed Audi RS2 Avant, the first RS Audi.
Why the S2 matters
The car created a clear bridge between rally-era Audi and the later S and RS ranges. Its styling is deliberately quiet, its cabin solid rather than theatrical, and its performance is deployed through traction rather than wheelspin. That combination is now recognised as a defining Audi formula.
Identity and originality
Many S2s have been modified because the five-cylinder engine responds well to tuning. A specialist inspection should verify engine code, turbo and management specification, quattro driveline health, corrosion repairs and the completeness of model-specific trim. A car’s history and quality of work matter more than a power claim.
Frequently asked questions
When was the Audi S2 introduced?
The S2 Coupé appeared in 1990. Avant and saloon versions followed during the model’s production life.
What engines did the S2 use?
Both principal versions used 2.2-litre 20-valve turbocharged five-cylinder engines: the early 3B and later ABY.
How much power does an S2 have?
The 3B was rated at 220PS; the later ABY at 230PS, with an overboost function.
Is the S2 the same as an RS2?
No. The RS2 was a more specialised Porsche-developed Avant with 315PS and unique chassis, braking and trim details.
Was there an S2 saloon?
Yes. The four-door S2 saloon is the rarest regular-production body style.
