Just unveiled at the Geneva Auto Show is the 2010 Lamborghini Murciélago LP670-4 SV. The number 670 represents the car’s metric horsepower rating (661 bhp in the U.S.), the SV stands for SuperVeloce (extreme speed) and the number 4 signifies all-wheel-drive.

The bump in horsepower from the standard Murciélago’s 640 hp (631 bhp SAE) was accomplished with modified intake system and increased valve lift. According to the factory, the 30-horsepower gain helps to push the new SV to 100 km/h (62 mph) in 3.2 sec. Top speed of 212 mph is reached with the standard rear spoiler. A larger rear “Aeropack Wing” can also be ordered to improve stability at high speeds, though the top speed is then reduced to 209 mph.

To further enhance performance, the SuperVeloce went on a diet with lighter components such as a new exhaust system, optimized high-strength sectional steel for the chassis, and sport bucket seats covered with Alcantara. All contributed to the car’s overall weight reduction of about 220 lb.

On the outside, a redesigned carbon-fiber front spoiler is pulled forward and painted in matte black to emphasize the SV’s increase in power. Larger air intakes for the front brakes are installed, with additional vents in place on the fenders for better cooling. At the rear, a single, flat exhaust tip is complemented underside by a two-level carbon-fiber diffuser.
