Drive-by-wire engine management and continuous variable valve timing are partially responsible for the Murcielago LP640’s power boost, and this year the E-gear transmission option receives recalibrated “thrust mode” acceleration programming. Also new for the Murcielago is an optional navigation system that’s integrated with the standard Kenwood audio system and its 6.5-inch display. The new audio system is compatible with DVD, MP3 and WMA formats.
