         Sinopec circuit features long straights ending with violent sharp brakings ,  fast turns that require  perfect car balance and many slow and medium speed corners . The most violent braking point is at kurve 8 where cars brake from 313 km/h and seventh gear to only 73  and first gear loosing 2.121 KW of kinetic energy .
