The 2005 Jeep Hurricane concept car could be steered by which wheels?

The 2005 Jeep Hurricane concept car could be steered by all four wheels.

Its Chrysler-designed four-wheel-steering system gave the Hurricane several unusual maneuvering abilities. In one mode, all four wheels turned in the same direction, allowing the vehicle to crab sideways without changing its heading. In another, the front and rear wheels turned in opposite directions, producing a claimed zero-foot turning radius.

The Hurricane was unveiled at the 2005 North American International Auto Show in Detroit as a dramatic engineering exercise rather than a production model. It combined a lightweight structural carbon-fiber body with twin 5.7-liter HEMI V8 engines, one at each end, producing a combined 670 horsepower.

A common mix-up is confusing four-wheel steering with four-wheel drive. Four-wheel drive describes which wheels receive engine power; four-wheel steering describes which wheels can change direction. The Hurricane had both systems, but its crab-steering and zero-radius demonstrations came specifically from steering all four wheels.
