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. Other weight saving tricks include carbon ceramic brakes with aluminium calipers, titanium exhaust, cameras instead of heavy door mirror mechanisms, and carbon fibre and aluminium wheels. 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.

Mercedes signs joint venture to build carbonfibre parts

Not to be outdone by BMW’s joint venture with the SGL Group to manufacturer commercially viable carbonfibre-reinforced plastic (CFRP) for the electric Megacity Vehicle, Mercedes has announced a joint venture with Japanese company Toray Industries to manufacturer and market its on CFRP automotive parts. The deal was signed in Germany today, with Toray taking a 50.1% stake, Daimler holding 44.9% and the remaining 5% being taken by other shareholders. The two companies started working together in March 2010, and while Toray has been working on the materials and moulding processes, Merc has designed the automotive parts and the technologies to join the parts together.
