The new and passionately developed Lamborghini Murcielago LP640

Gearbox and transmission: improved efficiency and strength

More power and higher torque call for superior gearbox component performance. To meet these new demands, the new Murciélago LP640 features a modified six-ratio gearbox as well as a tougher rear differential and new axle shafts. On request, the e-gear automatic gearbox is also available equipped with the new dedicated "Thrust" (acceleration programme) mode.

Just like its predecessors, the Murciélago LP640 features permanent four-wheel drive, based on the reliable Lamborghini VT (Viscous Traction) system. The system is self-governing and does not feature any electronic controls. The drive force is usually divided between the front and rear axles in the ratio of 30 to 70. An independent control circuit adjusts the distribution of the drive force depending on dynamic oscillation, weight distribution and the relative friction factor in perfect synchronisation with the Visco clutch. In extreme cases, up to 100% of the drive force can be applied to a single axle.

Electronics: a "closed loop" for total control

The electronics have also been updated. The modified engine control units improve engine performance and drivability thanks to closed loop control. Every engine and vehicle parameter is managed and controlled by three master control units and a satellite control unit. The master control units consist of two Lamborghini LIE engine control units, a Lamborghini GFA (Auxiliary Function Management) control unit and a Lamborghini PMC (Power Motor Control) satellite control unit. The control units are interconnected by a CAN Bus line.

Frame and chassis: perfect harmony

The body of the Murciélago LP640 with its characteristic scissor doors is created from the prized union of sheet steel and honeycombed carbon fibre, glued and riveted together.

Driving, handling and stability at high speed are enhanced by new springs and stabilisers, as well as by a redesigned electronically controlled damper. The anti-dive and anti-squat features on the axles, which efficiently prevent so-called brake diving and squatting, have not been changed. The two springs on every rear wheel, the single spring on every front wheel and the damper are placed coaxially.
