The provider determines the CdA value and predicts a travel time for the competitions available in the provider’s data set. A detailed test guide for the best possible measurement can be found here.

The customer can drive the respective test track with different equipment and draw conclusions on suitable material based on the calculation of CdA- value and projected travel times.
