New since February 2016!

Rotronics, the French specialist for dynamometers, delivered us in February 2016 probably the most accurate single roller 4wd dynamometer:
Rotronics Autoscan Fi X4+

Our specifications were
- maximum precision
- maximum repeatability
- axle synchronization to 300 km/h
Almost a whole year claimed the search for the perfect chassis dyno. After a trip to France, extensive tests and many discussions, we were sure that Rotronics is delivering the best four-wheel dynamometer with axle synchronization!
Thanks to the ISO-Speed axle synchronization, every vehicle - no matter which drive system - can be driven on the dyno, just like on the road. The enormous precision and the powerful software in the background make this dyno a perfect tool for tuners.
