2007 Lamborghini Murcielago LP640 Roadster features a 6.5 L engine, now producing 640 bhp, improving performance substantially. Like the base Murciélago, the engine is mounted backwards, with the transmission in front of the engine and the differential behind it, instead of a transaxle normally seen on mid-engine cars.
