Well, there's another embargo blown. HUMMERForums dropped all the images they had of the HUMMER HX concept that was due to be officially unveiled in a scant five days, and Jalopnik followed suit. So here it is, HUMMER's Wrangler-competitor in concept form, complete with a 3.6-liter SIDI E85 FlexFuel engine which sends power to all four wheels via a six-speed auto 'box. The HX is technically a convertible, meaning that the roof panels and modular rear can open or be stowed, while the interior instruments can be reconfigured depending on the type of driving you'll be doing. All the details are available in the press release after the jump.
