Just ahead of its Worthersee unveiling, Audi has released a video of the extreme TT ultra quattro concept being driven by its Le Mans-winning driver Andre Lotterer.
Thanks largely to the use of such materials as carbon fibre reinforced polymer for sections of the bodyshell, magnesium components in the floor and hinges, fiberglass-reinforced plastic for the suspension, a titanium exhaust system and wheels constructed from a mixture of CFRP and aluminium, the concept car enjoys a 300 kg weight loss over the TTS on which it is based.
Rather than producing 200 kW (272 hp) and 350 Nm of torque, the TTS’s 2.0 TFSI engine has been tweaked to pump out 228 kW (310 hp) and 400 Nm, meaning 100 km/h appears in 4.2 seconds, 1.3s faster than the series vehicle, and top speed is 280 km/h (174 mph).
