Sources on the ground at Germany's Nürburgring believe that this Lamborghini test car is a prototype for the Murcielago Superleggera - a lighter, even more intense version of the Lamborghini supercar flagship.
The black panels on this prototype point to the same use of lighter-weight carbon-fiber and plastic panels found on the recently released Gallardo Superleggera, meaning this super Murcielago gets a new engine hood, door panels, and central tunnel made out of the high-tech aerospace materials. Some of the glass has also likely been replaced by lighter-weight clear plastic, further reducing the Murcielago's mass. This prototype was also fitted with a massive rear wing, also likely crafted from carbon-fiber.
As with the Gallardo Superleggera, this new Murcielago is expected to get a power bump beyond its 640hp, further intensifying the gains made from the 'Lago's weight reduction. Just how close the Murcielago Superleggera will get to 700 horsepower is currently unknown. Also unknown is exactly when this newest Superleggera will be available to the insanely wealthy, but a public debut at one of this fall's European motor shows seems logical.
