The Murciélago is an all-wheel drive, mid-engined supersports car. With an angular design and an exceptionally low slung body, the highest point of the roof is just under 4 feet above the ground. One of the vehicle's most distinguishing features are its scissor doors. which lends to the extreme image. First-generation Murciélagos, produced between 2001 and 2010, were powered by a Lamborghini V12 which traces its roots back to the company's beginnings in the 1960s. The rear differential is integrated to the engine itself, with a viscous coupling center differential providing drive to the front wheels. Power is delivered through a 6-speed manual transmission. The Murciélago suspension uses an independent double-wishbone design, and bodywork features carbon fiber, steel and aluminum parts. The rear spoiler and the active air intakes integrated into the car's shoulders are electromechanically controlled, deploying automatically only at high speeds in an effort to maximize both aerodynamic and cooling efficiency.
The first generation cars were produced between 2001 and 2006, and known simply as Murciélago, sometimes Murciélago VT. Their V12 engines produced just under 580 PS, or Pferdestärke (German: horse strength), a European unit to measure horsepower, and powered the car to 100 km/h (62 mph) in 3.8 seconds. Subsequent versions incorporated an alphanumeric designation to the name Murciélago, which indicated their engine configuration and output. However, the original cars are never referred to as "LP 580s".
