Another new concept vehicle announced at last week's North American International Auto Show was the rugged Jeep Trailhawk. Designed for the open road — both paved and unpaved — the Trailhawk boasts a modern angular design and broad stance with a long 116-inch wheelbase. Outside are 22-inch wheels, signature seven-slot Jeep grille, and HID projector beam quad lamps, while the inside has sweet black and orange trim, spray-finish flooring, and removable, portable audio pod sound systems in each quarter panel. And a Jeep wouldn't be a Jeep without a little sky showing. The Trailhawk is an open-air concept — it has fully retractable windows all-around and removable glass panels over the seats and cargo compartment.
