Porsche 911 GT3 Cup

All race cars are technically identical, as are the Michelin tires and the fuel. The Porsche 911 GT3 Cup (the second generation of the 991) has been fielded in the Porsche Mobil 1 Supercup since 2017. The rear of the new 911 GT3 Cup houses a four-litre, six-cylinder flat engine, guaranteeing powerful propulsion. Thanks to thoroughbred motorsport technology, the compact engine with direct fuel injection delivers a peak performance of 357 kW (485 hp), making it the most powerful vehicle in the history of the Porsche one-make cup.
