The SuperVeloce’s V12 produces 670 PS (493 kW; 661 hp) at 8000 rpm and 490 lb·ft (660 N·m) of torque at 6500 rpm, thanks to revised valve timing and upgraded intake system. The car’s weight was also reduced by 220 lb (100 kg) through extensive use of carbon fiber inside and out. A new lighter exhaust system was also used. As a result of the extensive weight loss, the SV produces a power-to-weight ratio of 429 Bhp/long ton. Also standard were the LP 640’s optional 15-inch carbon-ceramic disc brakes with 6 piston calipers. In its June 2009 issue, Car and Driver magazine estimated that the LP 670–4 SV was capable of accelerating to 62 mph (100 km/h) from a standing start in just 2.9 seconds and on to 124 mph (200 km/h) in 7.4 seconds.
