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.

Ferrari 458 Challenge revealed

The Ferrari 458 Challenge It seems Ferrari had a bit of an issue when they decided they wanted to take the 458 Italia racing – it was just so good in standard form. So instead of giving the 458 Italia more power, they concentrated on making the 458 lighter and tighter to create the Ferrari 458 Challenge, unveiled this week in Bologna. The 458 Challenge gets exactly the same 562 horses out of its 4.5 litre V8 as the Italia.
