The 2022 Porsche 718 Cayman GT4 RS will have the same 4.0-liter unit that is fitted to the 911 GT3. That’s the one that revs to 9000 rpm and makes a peak of 493 horsepower. The output represents a 79-hp increase over the existing Cayman GT4 and 10 hp less than the engine makes in the GT3.

Unlike the regular GT4, there won’t be the option of a manual transmission.

Porsche is claiming a 3.2-second zero-to-60-mph time—half a second inside that for a PDK-equipped regular GT4—and a top speed of 196 mph, reached in seventh gear.
