One of Jeep's concepts, the Hurricane, has two V-8 engines, one in front and one in the rear. If the combined 670 horsepower isn't enough to grab you, how about the ability to turn all four wheels at once for a very, very tight 360-degree turn? For a concept car with a different take on getting out of a tight spot, and a not so rugged look, there's the Nissan Pivo.
Jeep is also showing off the more conventional Gladiator, whose retro-meets-nouveau stylings include a fold-down windshield, canvas roof, removable doors and expandable bed.
The low-slung Maserati Birdcage features some high-tech components, including a transparent heads-up display, camera systems, LED-based headlights and taillights, and wireless Internet access.
