As a result, the German car has now lost a total of 50 kilos after the championship’s sixth event at Portimao 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 Leon WTCC will carry no ballast - just like at Curitiba - while the Ford Focus and SUNRED Leon 1.6T cars will benefit from a 20kg reduction of their minimum weight.
