Later, in 2004 and 2005 Lamborghini Roadster was introduced, an upgraded model, with a bolder rear flank. The first Murcielago had 580-horsepower and a V-12 engine. Since it was put out on the market, over 2 000 such supercars have been sold.
In 2006 the car’s name was changed to Lamborghini Murciélago LP640 and it was improved with more power and multiple user-friendly characteristics. The initials “LP” come from Longitudinale Posteriore, which refers to the engine that is placed longitudinally, able to reach 633 hp at 8000 rpm. It has 6.5-litre engine with 640 horsepower. The transmission is placed in front of the engine with the differential behind it. On the outside, the changes were made with the intention to make the car more effective in aerodynamics: reshaped rear bumpers and exhaust, enlarged air intake on the left, revised suspension under the body of the car. The doors open on the lateral like its predecessors, the body is made of steel and carbon fiber and the wheels are new 18-inch Hermera alloys. Inside the Murcielago LP640 has a lot more room and improved audio system. Ceramic breaks, glass engine cover - which shows off the LP640's 6.5 L V12 engine - and chrome paddle shifters are optional. At the Paris Motor Show, a special edition was presented: The Versace LP640 featured completely white exterior, created as a special version of the LP640 Coupe, with Versace personalized interior. Another all-black Versace and Roadster Lamborghini were introduced.
The 2007 Lamborghini Murciélago LP640 has a 6.5 l engine and torque output improved at 487 pound-feet. The 3 500-pound bull can reach over 350 km/hour, making it the most powerful street-legal supercar. It is made of carbon fiber with 113.5 cm in height. Apart from being powerful, the engine is also very loud. The automatic transmission – called e-gear - is optional, for a “merely” $10 000 while the ceramic gears cost extra $13 000. The e-gear is also available equipped with the new “Thrust” mode, an acceleration program. It reaches 96 km/ph in 3.3 seconds. It is not as technically or electronically embellished as one might expect from German manufacturer, Audi. This superb missile will weaken you account of approximately $320 000.
