Porsche 992 GT3 Cup 

Stronger, faster, more spectacular: the new 911 GT3 Cup

Porsche has unveiled the latest generation of the world’s top-selling racing car: the new 911 GT3 Cup.

From the start of the 2021 season, this racer will be campaigned in the Porsche Mobil 1 Supercup as well as the national Porsche Carrera Cups in Germany, France, Asia and Benelux and for the first time in North America. The spectacularly styled Cup car is the first racing version based on the current 992 generation and the first makes-cup racer of the sports car manufacturer to feature a wide turbo-spec body. Producing around 375 kW (510 hp), it exceeds the output of its immediate predecessor by 25 horsepower. Moreover, the new GT3 Cup can run on synthetic fuels, which significantly lowers CO₂ emissions under racing conditions. The lap times of the completely new Cup 911 should be slashed by a good one per cent, depending on the track layout.
