The dynoKRAFT A200-4WD automotive chassis dynamometer combines affordable price and precise workmanship with best-in-class DAQ system and Software for comprehensive data analysis.

Our unique precise, passive electronic axis synchronization (using eddy current brakes) will keep both axis synchronized – rotational speed difference between front and rear axis <1RPM !

Roller width of 2170mm allow to test even wide-body race cars without problems. Wheelbase adjustment from as little as 2100mm to as much as 3300mm.

With dual 2000Nm eddy current brake the A200-4WD automotive chassis dynamometer allows to test up to 1000HP  (per axis).
The drum diameter of 516mm reduces tire wear drastically and help keeping the tire temperature under control during long test sessions.

The dynoKRAFT A200-4WD can be freely configured with extension modules (additional inputs, OBD Interface etc…) to match customer needs thanks to our upgradable design concept
