Indoor Facilities

They are fully equipped with vehicle charging infrastructure and enable simultaneous, controlled and repeatable testing on:

  • snow
  • ice
  • wet asphalt
  • dry asphalt

This allows winter testing to be performed 365 days a year.

The indoor winter test facilities allow speeds in excess of 100km/h and offer independent control of surface temperature and air temperature.

In addition, a series of cold boxes with direct access onto the test tracks can be used to soak vehicles to -40°C prior to testing.


Test tracks can be converted for split-μ (mu) and μ-jump testing of Anti-Lock Braking (ABS) and Traction Control (TC) systems.

They are used for tests including brake noise, snow ingress, cold start and driveability, and for winter tyre development and certification.
