Jeep Hurricane Before Sunday, the only way to get two Hemi V-8s in one garage was to buy two cars. But the Jeep Hurricane concept opens up garage space by putting two 5.7-liter Hemis in one vehicle. The carbon fiber-bodied concept vehicle is an exercise in making a powertrain versatile for on-road and off-road driving. But don't expect it to be built -- this one is just for fun, the automaker says. The heart of the Hurricane is a transfer case in the center of the vehicle that manages the combined 670 horsepower and 740 pounds-feet of torque. Power from an engine is directed through the transfer case to prop shafts that run alongside the vehicle. So power from one engine drives wheels on the left side of the vehicle, while power from the other engine drives wheels on the right side of the vehicle. In addition, the rotation of the prop shafts to the wheels helps keep downward pressure on the tires, Jeep says. That is a benefit for added traction in off-road driving. The powertrain is combined with a four-wheel steering system that enables the Hurricane to be able to spin around, or "crab" sideways to maneuver through tight spaces. The Chrysler group has taken out several patents on the drivetrain design and components, a spokesman said. Both engines are equipped with cylinder deactivation technology. So the Hurricane can be powered by 4, 8, 12 or 16 cylinders. The zero turning radius comes from a steering system that turns all four wheels inward. The steering system will also act as a conventional four-wheel steering unit, turning the rear wheels in the opposite direction of the front wheels to reduce the turning radius. For tight spaces, all four wheels can be turned in the same direction to enable the Hurricane to move sideways.
