Naturally Aspirated Flat-Six Engine – Unlike other 718 models that use turbocharged four-cylinder engines, the GT4 features a 4.0-liter naturally aspirated flat-six, delivering 414 hp (420 PS) and 420 Nm (310 lb-ft) of torque.
Manual Transmission as Standard – The GT4 comes with a 6-speed manual transmission as standard, giving purists a true driver’s car experience, while a 7-speed PDK dual-clutch automatic is also available for even quicker shifts.
0-100 km/h in Just 4.4 Seconds – The manual GT4 accelerates from 0-100 km/h (0-62 mph) in 4.4 seconds, while the PDK version does it in just 3.9 seconds, making it one of the fastest Caymans ever.
Top Speed of 304 km/h (189 mph) – The GT4 is the first Cayman to exceed the 300 km/h barrier, with a top speed of 304 km/h (189 mph), putting it in supercar territory.
Derived from the Porsche 911 GT3 – The 4.0L flat-six in the GT4 is derived from the 911 GT3 engine (992 generation), but tuned slightly differently to fit the mid-engine layout.
Track-Focused Aerodynamics – The GT4 has 50% more downforce than its predecessor, thanks to a fixed rear wing, large front splitter, and an aggressive rear diffuser, all improving track performance.
Upgraded Suspension from the 911 GT3 – The GT4 uses a modified version of the 911 GT3’s suspension, featuring Porsche Active Suspension Management (PASM) and a 30mm lower ride height for sharper handling.
First Cayman GT4 with PDK Option – Unlike the previous 981 GT4, the 982 GT4 offers Porsche’s 7-speed PDK dual-clutch transmission, making it even faster and more precise on the track.
Optional Carbon Ceramic Brakes – For serious track enthusiasts, Porsche offers PCCB (Porsche Carbon Ceramic Brakes), providing lighter weight, better heat resistance, and improved stopping power.
Clubsport Track Edition Available – Porsche released a 718 Cayman GT4 Clubsport, a track-only version with a roll cage, racing harness, and stripped-down interior, designed specifically for motorsport use.

The 718 Cayman GT4 is the purest modern Porsche—a 4.0L naturally aspirated flat-six (420hp), rear-wheel drive, and track-ready aerodynamics.
With the electric 718 coming soon, this is the last NA mid-engine Porsche for purists.
