Murciélago LP 640
In March 2006, Lamborghini unveiled a new version of its halo car at the Geneva Motor Show: the Murciélago LP 640. The new title incorporated the car’s name, along with an alphanumeric designation which indicated the engine’s orientation (Longitudinale Posteriore), along with the newly updated power output. With displacement now increased to 6.5 litres, the new car made 640 PS (471 kW; 631 hp) at 8000 rpm.
Murciélago LP 670–4 SuperVeloce (2009–2010)
The SuperVeloce’s V12 produces 670 PS (493 kW; 661 hp) at 8000 rpm and 660 N·m (490 lbf·ft) of torque at 6500 rpm, thanks to revised valve timing and upgraded intake system. The car’s weight was also reduced by 100 kg (220 lb) 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.
