The new 2021 best selling car in the world, the 2021 Porsche 911 GT3 Cup Racer Car, has the foundation history built back from the 992-generation 911. This year, Porsche added an extra 25 horsepower from the previous model and gained 510 horsepower in total. Furthermore, what's get the horsepower is not just what under the hood, but also thanks to the widebody that offers Turbo-style lightweight with wind-tunnel tuned aero and the striking swan-neck rear spoiler. Moreover, from the 911 RSR  front suspension, Porsche upgraded to double wishbones. And the first-ever GT3 Cup has electro-mechanical steering that elevates the performance of the vehicle. Inside, the car features diagnostics and telemetry, suspension adjustments from the full accessory kit when racing on the track.
