At 171 inches long, the HX is shorter than the H3. Its 3.6-liter direct-injected V-6 (which is making the rounds in multiple GM vehicles) is tuned make 304 horsepower and 273 lb-ft of torque -- more than the H3's I-5 -- and is E85 capable. The gearbox of choice is GM's 6L50 six-speed automatic, and there's a full-time 4WD system with a locking center differential. Stopping power comes courtesy of massive 15-inch Brembos on all four corners, with six-piston calipers in the front and four-piston ones in the rear. The binders are hidden behind 20-inch wheels wearing custom 35-inch Bridgestone Dueler tires.

The suspension is no slouch either. Fox Racing coilovers with 2-inch shocks and 2.5-inch springs support the independent front and rear suspensions -- though the lack of solid axles is sure to make purists balk -- and also provide plenty of wheel travel (9 inches in front, 11 at the rear) and ground clearance (13 inches). HX also has impressive approach (56 degrees) and departure angles (51 degrees). It can handle a 60 percent grade, 40 percent side slope, and ford two feet of water while seating four. To protect important bits underneath, the HX is fitted with a full underbody armor kit. Other heavy duty off-road equipment includes front and rear recovery hooks and a power winch on the front bumper.
