The latest version of the Lamborghini Murcielago doesn't come from the factory. Maybe from hell instead? It's Reiter's newest race-ready version of the outgoing Lambo supercar, and it's headed for an FIA-sanctioned event next year.

The new Reiter Lamborghini LP670 R-SV has been shown at the 24 Hours of Spa-Francorchamps. Built to GT1 standards, the new version of the Murcielago is tuned by the racing specialists with a more powerful 6.5-liter version of the Lamborghini V-12 that produces more than 650 horsepower. The skin of the car is recast in carbon fiber, and aerodynamic improvements make it suitable for Formula One racing as well. It weighs in at 2535 pounds after the modifications, before any race-required ballast is added.

Reiter says their Lambo P670 is ready for the world's most popular auto racing league. While the FIA only allows 6 makes to compete, this version's being pitched for the GT World Championships.
