Audi's concept TT debuts at the Worthersee tour as its Le Mans-winning driver takes it for a spin.
Short of the R8, the TT is Audi's most focused roadgoing driving machine – particularly in TT RS trim. But Audi has taken the formula a step closer to its LMPs with the TT Ultra Quattro concept. Initially revealed late last month, with the Worthersee tour kicking off in Austria, Audi has revealed more on its racing-derived super-coupe. The focus is on cutting weight, and to that end Audi has fitted carbon-fiber body panels, the R8 GT's buckets, a magnesium underbody, helping it shed 300 kg off the stock model's curb weight.
The resulting 1,111 kg (2,450 lbs) are motivated by a 310hp version of Audi's 2.0-liter turbo four, driving it to 62 in 4.2 seconds and topping out at 174 mph. Two-time Le Mans winner André Lotterer drives the concept in the clip below. It may be in German, but the sights and sounds require no translation.
