----------

Pneumatic shocks on the rear swing arm and large front struts absorb bumps for each pontoon. The pylons that attach the pontoons to the center pod further isolate the driver from bumps. Computer controlled drive-by-wire servos and auxillary servos steer the front wheels. A permanent magnet motor with 4:1 reduction gear, regenerative brakes, and Brembo electric piston brakes reside inside the hub of each wheel. Each motor is independently controlled by the drive computer, which can detect slip or grip.
