The power unit featured in the new 911 GT3 Cup is largely identical to the production engine in the 911 GT3 RS – same output of 450 bhp and same maximum engine speed of 8,500 rpm. Capacity of the Cup engine, however, is up from 3.6 litres on the former model to 3.8 litres on the new car, helping to increase engine power by 30 bhp
