CHASSIS DYNO

Multifunctional 4WD Chassis Dynamometer​​​​​​​​​​​​

The 4WD chassis dynamometer is a multifunctional development tool, supporting the testing and engineering portfolio for various applications.

Tests on a chassis dynamometer generate data with high accuracy and repeatability under real driving conditions while exactly keeping the requested ambient conditions stable. Different driving cycles also with changing gradients are possible. The tests can be done either with a driver or with a driving robot.
