Spy photographers have spotted a rather suspicious looking Lamborghini Murcielago out on the roads of Europe. While the body of the prototype remains relatively unchanged from the current Murcielago, the car's large rear wing indicates that something special lies beneath.

All indications would seem to suggest that this is a prototype for the upcoming Lamborghini Murcielago SV — a more high-performance version of the Italian supercar.

Reports surfaced late last year that Lamborghini was developing an SV version of the Murcielago to mark the car's production end. As with previous Lamborghini SV models, the Murcielago SV will ditch its all-wheel drive system for a lighter rear-wheel drive setup. To further save weight, Lamborghini will attach a fixed spoiler to the Murcielago — instead of the current car's automatic spoiler setup — and will also use several carbon fiber pieces to save on weight. In all, the Murcielago SV should shave about 100kg.

The Murcielago's power will also be raised — trumping the Reventon's 640 horsepower by at least 40 — which will further enhance the SV's performance. Lamborghini's E-gear is also said to be part of the SV package, but shift times should be cut in half.

Lamborghini promised to show one new car at every major auto show this year, and it looks like the Italian automaker will keep true to its word. Look for the Murcielago to debut at the Paris Motor Show later this year.
