Designed to be an even more adventurous and purpose-built class than Group B, the FIA’s Group S class was scrapped before a single car ever raced in the series. That means that Audi’s Sport Quattro RS 002, designed as a prototype for the series, has been driven by a remarkably small number of people.

Ken Block today released a new video in which he became just the sixth person to ever drive the car, and boy does he take advantage of the opportunity, driving it hard on an airstrip near Audi’s brand museum.

Driven back to back with Walter Rohrl‘s Monte Carlo-winning Group B Sport Quattro S1 E2, Block says that the Group S car would have been an improvement over the car that actually raced and won.

It has long been known that the Sport Quattro S1 (and its ilk) were very nose-heavy, which contributed to making them understeer quite a bit. Indeed, Block comes to the same conclusion, noting that the Group S car, thanks to its mid-engine layout, is a better-balanced car.

The Sport Quattro S1 E2 “was incredible, but this thing [the Sport Quattro RS 002 has] the same engine, so to feel that horsepower delivery but from a mid engine in a more balanced car, that was really fun,” says Block. “This thing [the Sport Quattro S1 E2] just understeers so badly, but this has just more of a nice turning balance. And I started to get the feel of what it would do and I was like ‘Okay, slow down,’ like, I got near to the edge of the grass once and I was, like, ‘Nope!'”

Indeed, the real advantage of Group S wouldn’t have been additional power, with engines capped at 300 hp (306 PS/225 kW). The FIA, though, planned to only require brands to homologate 10 cars to compete in Group S, rather than the 200 required for Group B competition. That, therefore, would have led to more creative designs, such as this one.

More history and driving is featured in the 15-minute video, so watch the full thing below, and Audi fans would be well-advised to keep an eye on the channel, which will be publishing more soon, and will eventually publish a new Gymkhana video called “Elektrikhana” in 2022.
