In 2021, PORSCHE revealed the 718 CAYMAN GT4 RS, the first in the CAYMAN lineup to receive the RS treatment, usually reserved for the 911 models. With a four litre naturally aspirated flat-six derived from the 911 GT3, it puts out 500 PS and 450 Nm with an rpm limit of 9,000rpm, which allows it to sprint from 0–100 km/h (0–62 mph) in just 3.4 seconds. It generates 25% more downforce than the GT4 variant, through a swan-neck attachment fixed rear wing. It lapped the Nürburgring Nordschleife 23 seconds faster than the GT4.
