Abstract
Abstract A high speed all terrain vehicle of the type having four wheel drive through a limited slip inter-axle differential that is effective to transfer driving torque between a front differential and a rear limited slip differential upon loss of traction of some of the wheels. Improved rough terrain mobility is achieved through an independent torsion bar suspension employing a power augmented roll steer characteristic to reduce the turning radius of the vehicle.
