Developed for Porsche One-make cups, the latest development of the Porsche 911 GT3 Cup is based on the 911 GT3 RS. The power unit featured in the 911 GT3 Cup is largely identical to the production engine of the 911 GT3 RS with the same output of 450 bhp and the same maximum engine speed of 8,500 rpm.

The weight of the racing model has been reduced significantly versus the lightweight road-going version. The GT3 Cup features a 44-millimetre (1.73") wider body at the rear, providing sufficient space for even larger wheels. Wider wheel arches also at the front clearly show that the front wheels are likewise new.

As an exclusive feature in the Porsche Mobil 1 Supercup, the 911 GT3 Cup comes with a modified, special exhaust system offering an even more dynamic and muscular sound. Another feature exclusive to the Supercup version is PCCB Porsche Ceramic Composite Brakes also available on Porsche's road models. Compared with the composite cast brake discs featured on the Carrera Cup cars, this reduces the weight of the car by approximately 20 kg (44 lb).
