The Murcielago LP640 is available as a two-passenger coupe or roadster, while the LP670-4 SuperVeloce is available as a coupe. The LP640 features a 6.5-liter V12 engine that produces up to 632 horsepower (Lamborghini states 640 PS or Pferdest�rke (German for "horse strength), a unit of power measurement commonly used in Europe, South America and Japan). A six-speed manual transmission is standard, and an available E-gear auto-shifting manual transmission with steering column-mounted paddles allows for split-second gear shifts. The LP670-4 SuperVeloce's horsepower is bumped up to 661, and the E-gear auto-shifting manual is standard, with the six-speed manual as a no-charge option. A permanent all-wheel-drive system with electronic traction control and an electronically-controlled adaptive suspension are standard equipment. Optional (standard on the LP670-4 SuperVeloce) light-weight carbon ceramic brakes offer superior durability and reduce brake fade, where the brakes become less effective due to overheating in extremely demanding conditions such as racing. An available (standard on the LP670-4 SuperVeloce) clear glass engine cover allows the owner to display the engine. The interior can be customized with exclusive materials such as Alcantara and carbon fiber trim (standard on the LP670-4 SuperVeloce). The LP670-4 SuperVeloce features extensively redesigned front and rear fascia, exclusive alloy-forged wheels, lightweight carbon fibre and Alcantara sport seats and a choice of rear wing spoilers. The 2010 Murcielago LP640 is carried over from 2009, while LP640-4 SuperVeloce is an all-new version.
