With its unmistakable HUMMER design and a compact, go-anywhere driving ethic, the HUMMER HX concept challenges the hierarchy of the trail.

Entry level Hummer

Embargo breaks galore, and WorldCarFans has laid their hands on one more of them. The Hummer HX Concept, or Hummer H4, will make its debut at the 2008 North American International Auto Show in Detroit this January 13 2008.

The Hummer HX Concept is one size smaller than the H3 SUV and measures 81 inches in width (2057 mm), a 103 inch wheelbase (2616 mm), 171 inch length (4343 mm) and is 72 inches high (1829 mm). The HX is essentially an open-air, two-door off-road four-wheel-drive car which seats four and is ready to take on the legendary Jeep. The removable (front) roof panels and modular, removable rear roof assembly can of course also be installed to protect the inhabitants from rain. There are three roof assemblies available, first a convertible set-up, a slant-back (coupe-like, think of the BMW X6 and Land Rover LRX Concept) or the traditional wagon like set-up for the most effective use of cargo space. In addition, the doors and front fenders can be removed as well. The slant-back will be on display at the 2008 NAIAS show.

Design is definitely easily identified as Hummer's own, but the HX will feature some new design cues like the 'chopped circle' motif. Many of the circles and oval used on the Hummer HX have been chopped on the top and bottom to create a feel that they were chopped down in order to fit them on the smallest Hummer in the line-up. The 'chopped circle' is used extensively in and on the car, for instance on the headlights and instrument cluster.

The Hummer HX Concept is powered by a 304 hp (370 Nm of torque) 3.6L V-6 VVT engine with spark-ignition and direct injection and runs on E85 FlexFuel (or unleaded regular). Stay tuned for live shots from Detroit.
