Hummer H3R Off Road Concept, 2007
Primarily to the efforts of the Team HUMMER racing team, led by Rod Hall, the HUMMER 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 SUV 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, HUMMER offers the H3 Alpha, which is powered by a new, 300-hp 5.3L all-aluminum V-8.
