Ken Block recently made the transition, from Ford to Audi. His relationship with the German premium brand took him to Audi Tradition, in Ingolstadt, Germany. The facility, which comprises of some unassuming, at first glance, buildings, houses the most legendary cars from Audi’s rich motorsport history. The cool part is that all of them get driven every now and then and Ken Block had a go in the rarest and ultimate Audi rally car – the Sport Quattro RS 002.

When you hear Audi and rally cars, you immediately think of the Group B Quattro, which dominated the rally stages in the 1980s. We all know that, by 1986, Group B had been canceled, but before that happened, an even crazier class was considered – Group S. Obviously, it never saw the light of day, but manufacturers still made prototypes for it. Audi came up with the mid-engine Quattro RS 002, of which only one was made.

The Ken Block YouTube channel gives us an introduction to what looks to be a series, in which the head hoonigan takes Audi’s prized motorsport possessions for a spin around the Ingolstadt facility. And what better way than to start with the company’s ultimate rally car that never officially raced.

Before Ken takes the one-off racing prototype for a spirited drive, the hoonigans go through the evolution of the Audi Quattro. They go through all years of the Quattro rally cars and follow the evolution of the liveries and colors used, as well as “how the fenders grow”. We also see a visual representation of the Sport Quattro’s 320 mm (12.6 inches) shorter wheelbase, compared to the normal car.

Ken first takes a drive in the Audi Quattro S1 E2, which was also driven by the legendary Walter Röhrl, at Monte Carlo. “This, you know, was one of the dream cars”, Ken explains, after which he gets inside and lights up all four tires.

The Quattro S1 E2 was a prelude to the main event – driving the Quattro RS 002. The Group S prototype features the same 2.1-liter turbocharged inline-five unit, but in here it makes the full 700 horsepower. It’s mated to a six-speed manual gearbox and is mounted in the middle, behind the driver, which according to Ken makes the car turn in as crisp as possible.

After driving both cars, Ken quickly points out how much better the Group S prototype drove than the S1, which “understeered like crazy”. They wouldn't let Ken do donuts in the prototype, but for the grand finale, he roasted the tires of a 2022 Audi E-Trong GT.

Words can only tell so much, so if you are curious how a mid-engine, 700-horsepower, 2,200-pound (1,000 kg), prototype rally car moves in the hands of an experienced YouTube Gymkhana sensation, click on the video below and enjoy some epic turbocharged, inline-five, rally noises.
