Like its meteorological namesake, the Hurricane can spin around its
vertical axis. To accomplish this, the front wheels pigeon-toe inward as the
rear wheels splay outward, and then the left-side wheels rotate in opposition to
the right ones. The action is masterminded by a patented transfer case dubbed
the T-Box. In existing 4x4 vehicles, power routes horizontally from the engine
to the wheels across the front and/or rear axles. The Hurricane´s two
transmissions, however, meet in the T-Box, transferring the Hemis´ combined
muscle through brake-controlled prop shafts to independently sprung side axles.
The T-Box directs the wheels to spin forward or backward, while the steering
system articulates them left or right, moving the vehicle forward or in reverse,
or letting it turn in place. Its four-wheel steering has two modes. One steers
the front wheels in opposition to the rear ones, tightening the turning radius,
and a second mode steers the front and rear wheels in the same direction,
allowing the Hurricane to skitter laterally, like a beach crab.
