The original Audi S4, built from 1991 until 1994, was a performance-oriented version of Audi's 100 saloon/sedan. All subsequent S4s since 1997 have been based on the Audi A4; and as the A4 has evolved from one generation to the next, so has the S4. All S4s have gained a more powerful internal combustion engine, larger uprated brakes, firmer suspension, and larger roadwheels have always been amongst the many upgrades the S4 receives over its mainstream 100 and A4 siblings. Like their non-sporting counterparts, all S4 variants have had longitudinally oriented, front- mounted engines. A single turbocharged 2.2 litre inline five-cylinder powered the original C4 version, a 2.7 litre 'biturbo' V6 engine powered the B5 generation, B6 and B7 versions shared a common 4.2 litre V8 engine, and the recently introduced B8 generation uses a supercharged 3.0 litre V6 TFSI engine.
