A modern Audi might just be an overpriced Skoda driven by a sunglasses-wearing, tail-gating douchebag, but there was a time when to drive an Audi was the understated choice.

All that changed in the 1980s though, when the Ingolstadt firm decided to pair a revolutionary all-wheel-drive system with a brilliant turbocharged five-cylinder engine. Audi weren’t actually the first manufacturer to insert all-wheel-drive into a production performance car (that title goes to Jensen and their fantastic FF), but they were the first to do it for the masses(ish).

Audi entered their new car into the World Rally Championship’s recently formed ‘Group B’ category, winning two world championships and rendering all two-wheel-drive competitors obsolete overnight. No car without all-wheel-drive has ever won the championship since.

The Technic replica of that championship-winning Audi S1 quattro pictured here comes from Eurobricks’ dokludi, and it’s as brutally ugly as the real thing. It’s accurate on the inside too, with working steering, all-wheel-drive, gearbox, inline five-cylinder engine, suspension and a full roll cage.
