The 718 Cayman GT4 RS is the first Cayman to receive Porsche's RS treatment, taking the GT3's 4.0-liter naturally aspirated flat-six and mounting it amidships. The engine produces 493 horsepower at 8,400 rpm and revs to 9,000 rpm, paired exclusively with a seven-speed PDK. A swan-neck rear wing and front diffuser generate roughly 25 percent more downforce than the GT4. Porsche quotes a 0-60 mph time of 3.2 seconds and a 196-mph top speed, and the car lapped the full 20.832 km Nürburgring Nordschleife in 7:09.300. It is one of the most extreme road-going 718 variants.
