Especially after the displacement of GT3 R has been increased to 4 liters GT3R, a hybrid version of GT3UP was released this year. The front spoiler is reduced by 15mm to provide greater downforce for the front axle; The shape of the tail wing is more exaggerated than that of the RS model, and its width is increased from 1.46m to 1.7m, which brings greater downward pressure to the rear axle.

Kloc-0/ 1 GT3 Cup S, the new car has been updated and developed on the basis of Cup S, and GT3R still uses Porsche's classic opposed six-cylinder engine with a displacement of 4 liters. This engine can provide 480 horsepower, and the power is transmitted by a sequential 6-speed semi-automatic gearbox. Due to the competition, 9 1 1 GT3 R has been strengthened and slimmed down, so its weight is only 1200 kg. The car is equipped with ABS, TCS, and an electronic throttle system that can display the shift indicator light.
