Despite a change-up in power at the top with the naming of a new CEO just a week ago and a firm commitment by GM to sell the brand, Hummer is continuing merrily on its way to SEMA with a three-pack of concepts based around the H3.

The first, an H3T truck-based vehicle called the 'Weekend Warrior', offers the basic H3T package plus a more powerful engine and enhanced suspension developed with assistance from the company's off-road racing program. With 70hp (52kW) more power on tap from the 5.3L V8 engine thanks to LS2 cylinder heads, a higher-lift camshaft and other bits and pieces, all sourced from GM's Performance Parts division, the Weekend Warrior is considerably peppier than its H3T Alpha donor.

Similarly, Hummer has replaced the stock rubber with a set of 35-inch-tall BFGoodrich Baja T/A tires on 20-inch wheels, added Light Racing JounceShocks and two-inch diameter Rod Hall Racing piggyback reservoir shocks, enabling the H3T Weekend Warrior to undertake some serious high-speed off-road work without endangering the mechanical integrity of the truck. For those places that the H3T just can't go, there's a KTM 450 SX-F dirt bike in the bed, held in place by the H3T's cargo management sytem.

The H3X Concept is based very heavily on production accessories for the H3 Alpha, but adds new 18-inch wheels with a unique finish, 35-inch-tall all-terrain tires, black chrome accents, body-colored rear bumper extensions and clear turn signal and side repeater lenses. The exterior is painted a distinctive Canyon Metallic color from PPG that is complemented brilliantly by the black chrome details and 18-inch wheels. The interior features black leather trim on the seats, console armrest, door armrests and shift knob that is accented with orange stitching. It also features custom mats with orange piping and a headrest DVD entertainment system that is available from Hummer Accessories.

The third model is from Four Wheeler Magazine, dubbed 'Project Trailhugger'. The first thing most folks will notice is the satin paintjob, achieved by adding a special PPG flattening agent to a clear coat and sprayed over the factory Victory Red paint job. All bright-colored trim was then painted flat black to complete the no-nonsense look. The Trailhugger has the goods to back the look up as well, with the same Rod hall and Light Racing suspension setup as the H3T Weekend Warrior.

Simulock 16-inch wheels in flat black mated to big BFGoodrich Mud-Terrain T/A KM2 tires give the vehicle solid grip, and a Gobi Stealth roof rack system helps bring all the gear necessary along for the ride. The Trailhugger's engine remains stock, but an array of accessories including a Warn XD9000 winch and a wireless remote-operable perimeter lighting system add that something extra.

All three Hummers will be on display at SEMA, which runs from November 4-7 this year.
