Porsche 718 Cayman GTS 4.0: PDK or manual, and what changes the buying decision
When Porsche put the 4.0-liter naturally aspirated flat-six in the 718 Cayman GTS, it fixed the one complaint people had about the turbocharged four-cylinder 718: the sound and the way it revs. The GTS 4.0 is the car the enthusiast market asks for by name. The decision most buyers get stuck on is the gearbox.
The verdict in sixty words
Manual if the car is a weekend toy, a canyon car or something you intend to keep. PDK if it is a daily driver, a track car you want to be quick in, or if you are buying with resale in mind in a market that increasingly wants the easier car. Both are the same engine and chassis. Neither is the wrong answer.
The facts
The GTS 4.0 uses a 4.0-liter naturally aspirated flat-six with a 7,800 rpm redline. Porsche rates it at 394 horsepower. The six-speed manual was the only gearbox when the GTS 4.0 launched for the 2020 model year; the seven-speed PDK dual-clutch was added as an option from the 2021 model year. Porsche's own figures put the PDK car quicker to 60 mph than the manual by roughly half a second because of launch control and faster shifts. The chassis is the same: GTS suspension with PASM lowered 20 mm, Porsche Torque Vectoring with a mechanical limited-slip differential, and the Sport Chrono package as standard.
How they feel different
The manual has a long throw by modern standards and a tall sixth gear, but it has auto rev-matching in Sport mode and the clutch is light. It makes the car feel smaller and more involving on a back road. The PDK makes the same engine feel more urgent because you are always in the right gear, and in traffic it is simply easier. On a track day the PDK car is the faster car for most drivers. On a Sunday morning the manual is the one you remember.
What to check on any GTS 4.0
- Build sheet from the VIN: 18-way adaptive sport seats, the GTS interior package, Bose or Burmester audio and front axle lift change the value and are easy to confuse between cars.
- Over-rev report from a Porsche dealer or specialist. This is the single most useful document on any modern Porsche.
- Service history, including the oil change interval actually followed.
- Tires: these cars are sensitive to mismatched or aged rubber, and the correct N-rated tires are not cheap.
- Paint protection film and any bodywork, because many of these were bought to be driven hard.
