The Murciélago sports a 6.2-litre version of the Lamborghini V12 engine, a six-speed manual or six-speed sequential automatic transmission, and four-wheel drive. It also has a rear spoiler that can be raised to an angle of 70 degrees, side mirrors that fold in to improve aerodynamics, and side scoops that automatically open to the needed size to let in just the right amount of air needed to cool its engine. The 2008 car's fuel economy is 8miles per US gallon (29L/100km; 9.6mpg-imp) city and 13miles per US gallon (18L/100km; 16mpg-imp) freeway, making it the least efficient 2008 car for city and highway driving, according to the EPA.
The coupé's base price is US $313,000, which is US $107,000 more than its smaller sibling, the Lamborghini Gallardo.
In 2006 the Murciélago's engine was replaced by a stronger 6.5-liter engine and the car's name was changed to Murciélago LP640. For the 2007 model year Lamborghini did the same with the roadster model, which is now called Murciélago LP640 Roadster. Both versions received a minor facelift.
The name Murciélago (pronounced moor-thee-EH-la-go in traditional Castilian Spanish and moor-see-EH-la-goh in Spanish of Latin America) means "bat" in Spanish. A bull by this name survived 24 sword strokes in an 1879 fight at the arena of Córdoba, and fought with such passion and spirit that the matador chose to spare its life, a rare honor. In another Lamborghini tie-in, the bull was later presented as a gift to Don Antonio Miura, who was a noted breeder and whose bull ranch the Lamborghini Miura was named after, and went on to sire a line of famous fighting bulls.
The LP640 version was first shown at the Geneva Motor Show in March 2006, as a facelift for the coupé version. It features a 6.5Litre engine, now producing 472kW (642PS; 633bhp), improving performance substantially. Like the base Murciélago, the engine is mounted "backwards", with the transmission in front of the engine and the differential behind it, instead of a transaxle normally seen on mid-engine cars. There were also a few minor external changes, primarily to the low air intakes.
