AWD Dynamometers
Full time AWD vehicles are designed to provide maximum performance regardless of road conditions. In cases where traction is less than ideal, a vehicle may be designed to improve stability and traction at the expense of power. This means adding torque to a spinning wheel or retarding of timing. In order to properly test an AWD vehicle for peak performance, an AWD chassis dynamometer must be able to simulate ideal road-load conditions to the vehicle. This approach allows the vehicle to be evaluated under "optimum" operational conditions; whereby torque is distributed to the vehicle's tires in the same manner that would normally occur when a vehicle has equal traction at all four drive wheels, and is therefore operating at peak efficiency.
