Murcielago SV

Rumours about a lightweight version of the Lamborghini Murcielago are thickening, with technical figures and styling details apparently leaked to online sources.

The Murcielago LP670-4 SV is said to produce 661bhp (the name once again denoting PS rather than horsepower), a healthy 30bhp more than the current LP640 (pictured) and even better when mated to the 100kg the SV will apparently drop from the 1665kg standard car. It means the 0-60mph sprint drops to 3.2sec and top speed rises to 213mph.

As the -4 suffix suggests, the car while remain all-wheel drive. Carbon ceramic brakes are said to be standard fit, too - probably helpful when it comes to hauling in a ton and a half of hypercar. Styling is likely to be much more aggressive to mark out the more hardcore Murcielago, with liberal use of carbon fibre and matte black paint suggested. Let's hope a big SV vinyl will be on the options list like it was with the stripped-out Diablos. Inside, expect a mix of carbon fibre and alcantara.

Prices are predicted to be around 25 per cent more than the LP640, meaning the SV should set you back £250,000 - not bad value when stacked up against a comparable Pagani. A March 2009 unveil is on the cards, apparently, which ties in nicely with the Geneva motor show. If the SV shows its face there, expect a very limited run of LP670-4s from the summer. The SV will most likely be coupe only.
