ROTOTEST Chassis dyno
The test has been conducted using a ROTOTEST Chassis Dynamometer. The dynamometer is in reality a supreme engine dynamometer fitted to each drive wheel. The Rototest dyno is of hub-type design (in contrast to roller-type, or rolling road) and is being used by many of the auto manufacturers around the world in their research and development and quality assurance.
