Ken Block works with Audi on electric vehicles, so he took advantage of this new partnership by searching the automaker’s secret stash of racing cars and prototypes.
During a visit to the company headquarters of the automobile manufacturer in Ingolstadt, Block toured the heritage collection from Audi Tradition and drove two very special cars: a Group B Sport Quattro S1 E2 from Walter Röhrl and the once secret Group S prototype.
To freshen up, the original Audi Quattro brought all-wheel drive into the World Rally Championship (WRC) and initially dominated the series. But the boxy Audi was soon surpassed by Group B machines from Lancia and Peugeot. Audi created the Sport Quattro with a short wheelbase and developed it further until Group B was completely eliminated after the 1986 season.
With the Audi Quattro S1 E2, which Block drove in the video, a dream came true for him, as it was one of the cars that interested him in rallying in the first place.

The Group S prototype was supposed to be what came after the Sport Quattro. The Audi engineers kept the turbocharged inline 5 engine, but placed it in a mid-engine chassis that is not based on any production model. At least one prototype was built with S1 bodywork but withdrawn after it was discovered during testing.
Audi built several prototypes with complete Group S bodies, according to a 2016 Road & Route History, but most were crushed after the Group S category was deleted. The only survivor was hidden by a sympathetic Audi employee and only shown to the public in 2016. Before Block, Audi estimated that only five people had driven it.
Block and Audi recently announced a partnership for electric vehicle projects, but it’s unclear what exactly that partnership will bring about. At the end of the video, Block got behind the wheel of the 2022 Audi E-Tron GT and drifted around the Audi Quattro Racer. A teaser at the end of the video also indicated that Block will drive more cars from the Audi Tradition collection.
