Lamborghini has unveiled the most-awaiting 2007 Murcielago LP640, a refreshed version of its range-topping supercar. The new Murcielago is powered by a 6.5-litre V12, longitudinally mounted behind the driver (LP in LP640 means "longitudinale posteriore"). The new engine's increased displacement means output jumps to 631 hp at 8,000 rpm. It will be able to go from 0 - 62 mph in just 3.4 seconds. The exterior is made from carbon fiber and it has a new 18-inch shinning rims with 13.5 inch wide-tires show a perfect appearance. The vehicle is expected to be sold a premium model above the standard Murcielago.
