The powerful engine of the 718 Cayman GT4 RS gets mated exclusively to a 7-speed PDK dual-clutch transmission delivering lightning-quick shifts for maximum performance. The driver has the ability to select gears manually with shift paddles mounted on the steering wheel, or with a newly designed shift lever in the center console. With different gearing than the 718 Cayman GT4, the GT4 RS accelerates from zero to 60 mph in 3.2 seconds — a half-second quicker than the 718 Cayman GT4 with the PDK. Porsche specs indicate a top track speed of 196 mph.

Two of the most noticeable changes for the Porsche 718 Cayman GT4 RS when compared with the 718 Cayman GT4 are new air intakes behind the side windows, which replace the small windows on other 718 Cayman variants. The new intakes improve airflow to the engine.

To achieve this weight reduction, the hood and front fenders are made of carbon fiber reinforced plastic, and the rear window is lightweight glass.
