Lamborghini Murcielago LP640: This bull runs rampant

Here's a short update on the Lamborghini Murcielago LP640 including some great shots.

This spring, Lamborghini amps up its most extreme machine, the raging Murciélago supercar — named after a legendary fighting bull — with added power and meaner looks.

An updated 2007 model called the Murciélago LP640 replaces the 2006 Murciélago coupe. The "LP" stands for "longitudinale posteriore," which is Italian for "longitudinal rear" and indicates the position of the vehicle's massive V12 engine behind the cockpit.

The number 640 in the new moniker denotes the total hp rating of the tweaked V12 engine, up 60 hp from the outgoing Murciélago coupe's V12 thanks to a bump in displacement from 6.2 liters to 6.5 liters. Lamborghini says the added power shaves 0.4 seconds from the zero-to-62 mph sprint, bringing it down to a scant 3.4 seconds.

Owners can show off the heart of their beast with a new optional glass engine cover. Archrival Ferrari has offered similar transparent paneling as standard equipment on its mid-engine models for more than two decades, starting with the 1987 F40.

The LP640 has an extra intake just ahead of the driver’s-side rear wheel that pipes cool air to the oil radiator. The 18-inch titanium wheels are new and lighter, wrapped in performance Pirelli rubber. Racing tires are optional.
