Sheer, ungodly, instantaneous power is available from the Lamborghini Murcielago LP640’s V12 when the driver plants the accelerator to the floor. Forward thrust shoves occupants deep into the supple leather seats, the engine wails an aria that only Italian-tuned powerplants can, and the Murcielago behaves as though equipped with a bottomless well of power. For an enthusiast, driving this Lambo is equivalent to an anything-goes date with Jessica Alba (or Jesse Metcalfe, depending).
