Find out more about the new Onyx Concept packages for the 2010 Range Rover. Details inside.

Irish tuners Onyx Concept have released two new kits for the 2010 Range Rover Sport and Vogue.  Both the Platinum S and Platinum V packages combine to provide better engine performance, and a full set of body modifications.

Power on the 3.6-liter V8 turbo diesel engine can be boosted by 30% to 347 hp (259 kW / 352 PS), while the 5.0-liter supercharged petrol V8 engine is bumped up by about 26%.  The top shelf petrol now boasts 635 horsepower (474 kW / 644 PS) thanks to a remapped engine control unit, a new supercharger pulley, and undisclosed "other tweaks."

New front and rear bumpers were also installed, as were modified spoilers and new fender flares.  Parts were built out of both carbon fiber and fiber-reinforced plastic.  Interior mods include the generous use of buffalo-hide leather.

Pricing for the Onyx Platinum S and Platinum V packages have not yet been revealed.
