dynoKRAFT A200-4WD-ML

Single roller 4WD dynamometer

Affordable all-wheel-drive dyno with permanent mechanical axis link

Features highlight

  • 515mm [20,3″] rollers
  • 300km/h [186mph]
  • 2x 1000HP wheel power
  • mechanical axis synchronisation

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

The dynoKRAFT A200-4WD-ML features unique synchronization system.
It combines both mechanic and electronic axis link thus enabling extreme level of synchronization accuracy and dynamics.

Standard installation type is floor-top. Pit installation available on request.

Roller width of 2170mm allow to test even wide-body race cars without problems.

With two 2000Nm eddy current brake the A200-4WD automotive chassis dynamometer allows to test up to 2000HP  (1000HP per axis).
The roller diameter of 515mm reduces tire wear drastically and help keeping the tire temperature under control during long test sessions.

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