More technical information has leaked out about the final evolution of the Lamborghini Murciélago as the Bologna sports car maker prepares to present the project, which will be built in a limited production run, to its dealers and potential customers ahead of an expected debut at the Geneva Motor Show in early March.

Lamborghini has been buoyed after the success of the 20-off Reventón sports car which saw a restyled Murciélago with a revised interior that was themed on the F-22 Raptor fighter jet, able to command a retail price of 1 million euros. For this final edition of the ageing supercar, Lamborghini will again offer distinctive styling cues to set the car apart from the current Murciélago LP640.

Expected to be known as the Murciélago LP670-4, the new name follows the recent Gallardo LP560-4 in adding the letter '4' to denote the four wheel drive transmission, while the 670 refers to its increased power, it's muscular 6.5-litre V12 engine will have 30 CV extra over the current LP640 version (with 640 CV). It is reported that the 0-100 km/h acceleration time will be achieved in 3.2 seconds, a small improvement over the current car's 3.4 seconds, while overall top speed will rise by 342 km/h when the car is specified with a standard rear wing (the more aggressive large rear wing option limits speed to 337 km/h).

The new car will feature more striking looks in recent Lamborghini style. Sharper angles are a feature at the front, and new air intakes are sliced into the upper outer areas of the hood. At the side of the car the door mirrors have been redesigned, while the back is now much sharper and the distinctive bumper protrudes further, giving the rear end a much more aggressive look. The lower sections of the LP670-4 SV will be finished in a matt carbon fibre, while the upper sections, including the new wheels, will be finished in a highly polished gloss black. The car will come with a distinctive 'SV' badging as an option. Inside, the cockpit will feature the extensive use of Alcantara, while leather will be an option for the passenger seat.

Under the skin Lamborghini have targeted weight reduction as a priority, much as they have done on recent models such as the Gallardo Superleggera, and 100 kg is expected to be saved, bringing it weight to around 1550 kg. The use of carbon ceramic brakes (CCM) will be standard.

Lamborghini President and CEO Stephan Winkelmann is pretty upbeat about the Bologna based firm's ability to ride out the current global recession, releasing an upbeat year-end statement just before Christmas; and following the success of the exclusive Reventón, the firm will be limiting production of the Murciélago LP670-4 to 350 numbered units to be built over the next year, and it will be sold at a premium of 25-30 percent over the LP640. The project is being outlined in detail to its dealers and selected customers, along with a scale model, at a number of locations around the world this month.
