The Cars
The 911.
The 992-generation 911 GT3 Cup is a striking masterpiece, the first racing iteration to draw from the latest 911 road car and the inaugural one-make Cup racer to feature the bold wide-body chassis of the iconic 911 Turbo. With a formidable 510 hp—an increase of 25 horsepower over its predecessor—this precision-engineered machine delivers thrilling performance, clocking lap times that rival the IMSA GT3 R race cars. The enhanced power, traction, and aerodynamics brought an exhilarating leap forward, slashing lap times by up to three seconds in the Porsche Mobil1 Supercup. This newfound speed is coupled with extended component life, offering improved reliability and lower operating costs. The car made its highly anticipated debut in Porsche Carrera Cup North America in 2021, marking a new era of racing excellence.
The 718.
he new 718 Cayman GT4 RS Clubsport is poised to dominate both sprint and endurance races on the international stage, ready to carve its mark on the track. Its enhanced performance glides effortlessly over even the roughest asphalt, delivering a ride that’s as smooth as it is thrilling. With up to 9,000 rpm, the 6-cylinder naturally aspirated boxer engine, nestled in the heart of the car, eagerly awaits its next victory. It’s as mesmerizing as the 500 PS (368 kW) of relentless driving force, which the 7-speed PDK transmission with rigid suspension and shorter ratios sends to the rear axle without hesitation.
