About the 2020 Porsche Cayman GT4

The 718 Cayman GT4 answered years of enthusiast pleas by returning the naturally aspirated flat-six to Porsche's mid-engine lineup. The 4.0-liter engine produces 414 horsepower with the intoxicating soundtrack that made the original GT cars legendary. Derived from the 911 GT3's powerplant, it delivers linear power delivery and revs to 8,000 rpm with mechanical precision. The GT4 package includes track-tuned suspension, aggressive aerodynamics, and available six-speed manual transmission that connects driver to machine. Limited production and purist appeal have made this immediately collectible, with manual examples commanding premiums. The combination of naturally aspirated power, mid-engine balance, and GT department development represents the pinnacle of modern Cayman evolution. As Porsche moves toward electrification, the GT4 stands as potentially the last naturally aspirated mid-engine sports car from Stuttgart, ensuring its place in automotive history.
