Variant announced in November 2008.
In order to improve the racing, the circuit was modified for the 2021 Grand Prix by track consultants MRK1. Turn 7 was reprofiled, with the chicane removed and the hairpin widened. Turns 11-14 were removed and replaced by one long banked turn, and turns 17-20 were opened up. The resulting track length was 5.281 km, and is shown below.
