Four HUMMER H3-based vehicles will bulldoze their way into SEMA this year. All feature V8 engines and specific target markets such as outdoor enthusiasts and racing fans.

HUMMER will be represented by at least four special vehicles at SEMA 2009. They include two concepts called the H3 Moab and the H3T Sportsman.

The former is inspired by trails like the Moab rim. Power comes from the 221kW (300hp) H3 Alpha V8 and upgrades include of a Rancho 4-inch front suspension lift, a custom rear spring-over conversion, 35-inch BF Goodrich Mud-Terrain KM2 tyres and additional custom underbody shielding for extra go-anywhere abilities. Other accessories are a Gobi Ranger roof basket, lower grille mounted lamps, front and rear-facing cameras and half a dozen basket-mounted off-road lamps.

The H3T Sportsman is geared towards the outdoor enthusiast. Based on the Alpha V8, engineers added LS2 cylinder heads, a higher-lift camshaft and supporting components for an extra 51kW (70hp). It features a body colour-coded upper grille, a matte finish fuel door, right and left side lockable storage boxes for things like fishing gear or hunting kit, and all-weather floor mats and seat covers.

The third car was created by former Dakar stage winner Robby Gordon and his team. Although inspired by Trophy Trucks raced in the Baja 1000, it has a special chassis with racing suspension, air conditioning and windows all around. GM provided the V8 engine.

Rod Hall Racing made the last car on the list. It is a desert racer based on the H3 Alpha but with new suspension bushings, wiring and exhaust systems. Driver Chad Hall will pilot the car during the 2009 SCORE International Baja 1000.
