Following disappointing performance in the latest WTCC event at Curitiba, the BMW 320 TC cars will benefit from a further reduction of 20 kilos for the races in Sonoma.
This means that the German car has lost a total of 50 kilos after the championship’s sixth event at Portimão in June.
The Chevrolet Cruze remains the reference car according to the calculation based on the lap times set in the three previous events (Austria, Portugal and Brazil) and will be laden once again with the maximum 40kg ballast.
The SEAT León WTCC will carry no ballast (just like at Curitiba), while the Ford Focus and SUNRED León 1.6T cars will benefit (like the BMW) from a 20kg reduction of their minimum weight.
