Rotrak testing prototype variable drive supercharger in vehicle on dyno

Green Car Congress

The company’s engineers have a prototype system running in a B-segment donor vehicle on a dynamometer and are calibrating the control strategy to prove its driveability, performance, CO 2 and fuel economy benefits. Both solutions involve part load losses which compromise some of the fuel consumption savings made by downsizing.
