2007 Hummer H3R Off Road Concept

HUMMER H3R OFF-ROAD CONCEPT

Thanks primarily to the efforts of the Team HÚMMER racing team, led by Rod Hall, the HÚMMER H3 has quickly proved to be a formidable off-road competitor. It runs – and wins – in stock-class off-road races, where racers must rely on production chassis and powertrains. The H3R pays homage to the racing SÚV while pushing the envelope on what could be considered 'stock' – supposing the factory decided to drop in the 505-horsepower, 7.0L V-8 from the Corvette Z06. In addition to the high-powered engine, the H3R also sports a number of racing-inspired exterior modifications and an interior that blends racing functionality with boulevard comfort and convenience. No, a production H3 equipped with an LS7 engine isn't in the cards, but for 2008, HÚMMER offers the H3 Alpha, which is powered by a new, 300-hp 5.3L all-aluminum V-8.
