The third generation of the Audi S4 was based on the Audi A4 B6 model and even if it lived only for less than two years, it remained the A4 with the biggest engine installed on it by the factory.
In March 2003, Audi showed their latest innovation: the S4. It was available as a four-door sedan, station-wagon, and cabriolet. It was the answer given by Audi to the BMW M3 and the Mercedes-Benz C. While its main rivals offered 6-cylinders engines, the S4 entered the battle with a V8 and an all-wheel-drive system.

From the outside, there were little clues that could differentiate an S4 from a regular A4. The wheel-arches were enlarged to accommodate the wider tires. On the grille, the car-maker placed an S4 badge and in the rear, two exhausts came out under the apron. It wasn’t something that someone would notice until it got overtaken.

Inside, the S4 installed bucket-seats with leather. The instrument cluster was awarded an S4 badge on the background and the standard equipment was a long list.

The most important option on an S4 was the transmission. It was fitted as standard with a 6-speed manual and there was an option for a 6-speed automatic with sequential shifting if the driver needed. It was named Tiptronic and it was great for downshifting without destroying the clutch or the blowing up the engine. The 4.2-liter V8 monster under the hood was big enough to be installed in the luxurious A8 limousine, but it offered more horses. And that’s how the Audi has beaten the 3.2-liter BMW M3 and the Mercedes-Benz C32 AMG. And yes, the S4 was all-wheel-drive.
