Audi R8 GT

Audi R8 GT, in the back there is a re-worked 5.2 litre V10 making 412KW and 540Nm, good enough to punch the GT to 100Km/h in 3.6 second and on to a maximum of 320Km/h. shaving weight has obviously been a bit of a mission for the good people of Quattro Gmbh and it has involved the extensive use of both straight carbon fibre and carbon fibre reinforced plastic (CFRP).

The list goes something like this the rear hatch is now CFRp and saves 6.6Kg from up high in the R8 GT's centre of gravity,though weirdly it retain the gas struts for holding it open, which surely would shaved a few more grams. The rear bumper and sideblades are also CFRP,contributing a saving of 6.7Kg and the fixed,full carbon rear wing  the standard R8 has a speed dependant pop ip aerofoil with electric motors drops another 1.2 The bonnet is made of aluminium and much skinnier than before.When you slam it because you might just leave a hand print in the metal and saves 2.6Kg.

The wheels are forged and lightweight, the windscren is now thinner and the rear window are made of lightweight polycarbonate, while the distance unfriendly bucket seats are manually operated and much lighter.The carbon ceramic braking system has been lightly mass decontented there is a lighter battery and most of the car's sound deadening has been removed.all which contributes to a further20-ish kilos of lard reduction.Legend has it the removal of the carpetry alone resulted in a saving  some 8Kg,though one suspect that someone is using unusually heavy-duty mats in the standard R8 if that really is the case .possibly something woven from woolly mercury.
