Audi TT ultra quattro concept sheds 300kg & heads for Worthersee

The TT ultra quattro concept manages to tip the scales at 1111kg, 299kg less than the starting point – the TT S quattro – thanks to a new version of the TT’s aluminium space frame, carbon fibre reinforced plastic panels, carbon fibre for many body panels and some judicious use of magnesium.

The weight saving extends to the interior of the TT ultra quattro concept too, with carbon fibre used for the door and centre console trims and glass-fibre reinforced plastic base for the seats which saves 22kh alone. But despite the weight savings Audi hasn’t made the TT ultra quattro concept a hair shirt outing with goodies like leather seats, AirCon and electric windows still on offer.
