According to insiders, you're looking at the basis for the upcoming H4 — but whether they call it HX, H4, or H-ellion, it's pretty hard-ass. The Hummer HX Concept ($TBA) is all-Hummer, with full-time 4WD, 35-inch tires, an advanced front suspension with an electronic-disconnecting stabilizer bar, and an E85 FlexFuel 3.6L SIDI V-6. However, it also borrows some ideas long assocoiated with rival Jeep, including a removable roof panels, doors, and fender flares, and a modular rear roof assembly that can also be completely removed, turning the HX into a true convertible.
