Introduced in 1997, the version of the Audi S4 based on the A4 was destined to become an instant classic, and it certainly did. Fast, sophisticated and agile as a gazelle, it could hold its own against the very best from BMW and Mercedes-Benz, all in a classy, convenient and surprisingly easy to drive package. Instead of relying on the old turbocharged inline five-cylinder engine, the new S4 boasted a twin-turbocharged, five-valve-per-cylinder 2.8-liter V6.
This discreet sports sedan drove and handled like a supercar, a fact much appreciated from its legions of passionate buyers; it could reach an impressive 153 miles an hour, and accelerate to 60 in just a hair over 5 seconds, an eyeball-squishing acceleration by any standard.
The engine’s 265 horsepower were delivered to all four wheels using Audi‘s Quattro drive-train, through a superb six-speed transmission. Each turbo supplied a single cylinder bank, which meant that the engine had about as much horsepower as the old five-cylinder, but a lot more torque, which is crucial when driving power to all four wheels.
