The B9 S4's turbocharged V6 wasn't purely an Audi design — it was co-developed with Porsche.

Downsizing paid off in an unexpected way: by swapping V8 for supercharged V6, the B8 S4 became the first S4 generation to dodge the US gas guzzler tax entirely.

Not all B7 S4s are alike: from the 2007 model year on, Audi quietly swapped in a Torsen T-3 diff with a rear-biased 40:60 default torque split.

The B6 S4 was the first compact executive car ever sold with a V8 engine, putting it head-to-head with the BMW M3’s inline-six and the Mercedes C32 AMG’s supercharged V6.

The B5 S4's twin-turbo V6 ran five valves per cylinder — 30 valves total — a genuinely exotic valvetrain for a compact executive car in the late '90s.

Ayrton Senna owned a silver C4 S4 Avant — fitting, since he was also Audi's official distributor for Brazil.
