Lamborghini Murcielago SV

Lamborghini is working on a lightweight version of the Murcielago. At least 220 pounds lighter than the Murciélago LP640, the SV will have even more power than the 641-hp V12 Reventon. Sources also say that Lamborghini is working on a SV version of the Gallardo.

The Murcielago SV will loose the front differential and driveshafts saving this way around 90 lbs. Also the dietary lessons learned from the Gallardo Superleggera will provide the rest of the needed weight reduction. The car body panels will be made out of carbon fiber while th roof and the door panels from aluminum.

The interior will become carbon-fiber central, including the inner door skins, the seat shells and the center tunnel. Leather-lined door panels will be replaced by carbon, with a pull strap for a door handle, saving five pounds per door. Lamborghini also will strip out the audio system, and if it follows Superleggera precedent, it will happily sell it back to you as an option.

Under the hood there will be a 6.5-liter V12 engine that will deliver 680 hp and 516 lbs-ft. Also it will feature new, lighter exhaust internals to serve the dual missions of cutting weight and easing back pressure.
