LAS VEGAS – HUMMER’s iconic design and unparalleled capabilities have come a long way since the brand first transformed an austere military vehicle into a true automotive phenomenon in 2002. Since then, the division has unveiled a series of trucks that e xpress these core attributes, and add premium style and comfort. This combination defines HUMMER and inspires its loyal following.

HUMMER’s capabilities are tested by its owners every day in the real world, and also off-road in desert racing, in what’s perhaps the ultimate proving ground.

Team HUMMER consists of H1, H2 and H3 race trucks, all driven by the legendary Rod Hall and his sons, who also are accomplished off-road racers. The Hall team competes in the Full Stock class, featuring production-based vehicles with stock frames, stock suspension designs and production-based engines. In 12 years of racing, the team has garnered 10 class wins at the Baja 1000, 41 podium finishes in the Best in the Desert series races and five BitD class championships.

For the 2007 model year, HUMMER refines its offerings with two limited-edition models for H3 and H2, and a more powerful engine for H3. It also continues its enhanced warranty of four years or 50,000 miles on all HUMMER vehicles.

H3 – Roughly the same length as a midsize family sedan, H3 comfortably navigates city traffic and delivers HUMMER’s trademark crawling and climbing capability.

In addition to its impressive off-road capabilities that match those of the H2, the H3 also provides the refinement, comfort and convenience required for enjoyable on-road driving, with daring looks that make it immediately identifiable as a HUMMER . The interior is inviting and modern, blending premium cues with world-class craftsmanship.

For 2007, H3 receives a new, more powerful engine: the Vortec 3.7L with dual overhead cams and variable valve timing. This 3.7L inline five-cylinder offers an excellent combination of power and efficiency, delivering 242 horsepower (180 kW) at 5600 rpm* and 242 lb.-ft. of torque (328 Nm) at 4600 rpm.*

And less than a year after the H3’s debut, HUMMER expands the line with a new model called the H3 X*, based on the H3 Street concept shown at the 2005 Specialty Equipment Market Association (SEMA) show. The 2007 H3 X injects new energy into the HUMMER lineup, appealing to buyers with an interest in a customized appearance available directly from the factory.

H2 – H2 extends and refines H1’s rugged heritage by adding more creature comforts and maintaining off-road leadership. It’s a bold and youthful interpretation of what HUMMER means, in a more civilized package. Its extreme design makes sure that H2 has the eye-catching appearance – and brand recognition – of H1.

For 2007, H2 adds a limited edition model with a “Glacier Blue” exterior, rear-vision camera system, carbon fiber interior accents, rear-seat entertainment with DVD, and more. The rear-vision camera system also is an option on all H2 models for 2007.

H2's power is derived from the standard Vortec 6.0L V-8 that generates 325 horsepower (242 kW) at 5200 rpm and 365 lb.-ft. of torque (494 Nm) at 3600 rpm. The engine is mated to a heavy-duty Hydra-Matic 4L65 four-speed automatic overdrive transmission. Capable of traveling through streams 20 inches (508 mm) deep, climbing 16 inch (406 mm) steps and rocks, paddling through deep sand and outdistancing competitors in high-speed desert runs, the H2 can do just about anything.

H2 SUT – This variant of H2 offers added functionality and versatility. The passenger and cargo areas of the SUT can be configured for a variety of needs. When the vehicle needs to carry passengers in the rear seat as a conventional SUV would, the bulkhead (called the Midgate) at the rear of the passenger compartment remains upright, still providing a rear bed with more than 30 cubic feet (850L) of cargo space. However, when more cargo space is desired, the rear window can be powered into the Midgate, and the Midgate and rear seat can be folded forward to allow access into the now-expanded 4-foot by 6-foot (122-cm by 244-cm) pickup bed.

An express-down feature drops all vertical side windows and rear glass. An expansive sunroof gives passengers an open-air feel.

*Horsepower and torque SAE certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.
