The technology found in the Murcielago LP640 has not been modified. The engine in the LP640 forwards is the classic twelve-cylinder engine with 6.5 litre displacement. Only for this car, Lamborghini guarantees, an astounding 650 HP (478 kW) at 8,000 revolutions per minute (rpm). The huge torque, equal to maximum 660 Nm, ensures a powerful switch from any number of revolutions: even the slightest pressure on the accelerator is spontaneously transformed into thrust. The robotised e.gear changes gear faster than even the most expert driver. In addition, the permanent Viscous Traction four-wheel drive system ensures that every force is constantly translated into movement. As in the original Murcielago LP640, the Reventon accelerates from 0 to 100 km/h in just 3.4 seconds, with a maximum speed over 340 km/h.
