Prior to the DTM round at Moscow Raceway, the DMSB partly changed and redefined the procedure for the allocation of the performance weights. The rule change comes into force with immediate effect.
After the race, the average fastest lap times of the three best-placed drivers of each manufacturer in the drivers’ standings who were classified in the race will be determined. This average is determined from a minimum of 15 and a maximum of 30 laps. How many laps exactly is decided at random after the race. Then, the average for each manufacturer is determined from the three individual averages per driver, which is then used as the basis for the allocation of the performance weight in the same way as it was done before.
