Onyx Concept is coming to the SEMA Auto Show->ke216 and its bringing its long anticipated program for the Range Rover that will no doubt get its fair share of attention in Las Vegas.

The company's CEO, Trevor Musgrave, has made no bones about his excitement for the flagship Range Rover Aspen Ultimate Series. Rightfully so, too, considering that the program comes with a comprehensive upgrade that covers the SUV->ke145's aesthetics and more importantly, its 5.0-liter, V-8 engine.

The exterior upgrades are no less stunning as they are effective. Carbon fiber was predominantly used on the new components, which includes new aero fins, pillars, front air dams, mirrors, and diffusers. Taken all together, it gives the Range Rover a 27 mm (1.06-inch) wider wheelbase .

Those elements come into play when you also take into consideration the engine upgrade Onyx Concept did to the SUV, increasing the output from its 5.0-liter, V-8 engine to an astounding 625 horsepower, 115 horsepower more than the standard 505 ponies the Range Rover has inside its belly.

The program will be showcased at the 2013 SEMA Auto Show together with the Aspen Rogue program, an equally impressive kit that we're pretty excited to see too.
