2021 Porsche 718 Cayman GT4 Review: The Reason We Drive

When the Porsche Cayman was first introduced back in 2005, most saw it simply as a Boxster with a hardtop, but people quickly came to realize that this is one of Porsches best driving models in the past few decades (not that Porsche builds bad handling cars). Now in its third generation, this 2-door 2-seater is sharper than ever, but Porsche likes to remind us just how good it is at manufacturing medical-grade scalpels, which is why we have the ridiculous glory that is the 2021 Porsche 718 Cayman GT4. The GT4 was released last year to massive praise from the media and public alike. Its 4.0-liter flat-six gas engine produces 414 horsepower and 309 lb-ft of torque that steals the show, and for 2021 Porsche now offers the GT4 with its excellent 7-speed PDK dual-clutch automatic transmission, making it an even more potent track weapon. The 2021 Porsche 718 Cayman GT4 goes up against fellow German rivals such as the BMW M2 CS and Audi TT RS.

2021 Porsche 718 Cayman GT4 Changes: 🚙What's the difference vs. 2020 Porsche 718 Cayman GT4?

The GT4 was a new addition to the 718 Cayman coupe range for 2020, so not much needed updating for the 2021 model year. Nevertheless, there is one significant change. When the GT4 was launched, it was a manual-only model. However, for 2021, Porsche has broadened the car's appeal by offering a 7-speed PDK dual-clutch automatic transmission. This improves the accuracy and quickness of shifts, but we're just happy that you can still grow your own gears if you like and as you should.

Pros and Cons

  • Intoxicating engine note
  • Razor-sharp dynamics
  • It's still relatively practical
  • High reliability rating
  • Standard manual transmission
  • It's expensive
  • Not a lot of standard features
  • The second gear is a tad long

Engine and Transmission

There are a few elements that make the 718 Cayman so great: It's badass looks, amazing chassis and suspension setup, and finally its engine. We applaud Porsche for refraining from going down the predictable turbo root, and instead going for a high-revving naturally aspirated motor. This 4.0-liter flat 6-cylinder develops 414 hp and 309 lb-ft, which is just enough to make the 718 Cayman GT4 coupe feel fast, but not scary fast. The best part is running the needle to the redline; the road will make anyone feel like a pro driver. Power is sent to the rear-wheel drivetrain via a 6-speed manual transmission or an optional 7-speed PDK dual-clutch, which is brutally efficient, but detracts from the car's engaging personality. The GT4 will sprint to 60 mph in 4.3 seconds in manual guise, or 3.8 seconds with the PDK transmission, and will reach a top speed of 178 mph. Though hardly worth mentioning, the automatic is marginally more fuel efficient.

Verdict: 🏁Is the 2021 Porsche 718 Cayman GT4 a good coupe?

The problem with making an already good sports car faster and more capable is that you often lose the essence or balance of what made that vehicle good in the first place. The base 718 Porsche Cayman is already one of the best driver's cars in the world, so for Porsche to have made the GT4 even better is nothing short of a miracle. Yes, it is definitely more hardcore and less easy to live with on a daily basis, but it's not a completely stripped out track car, and those buying it for what it is will be more than happy to live with it.

They will have to live with a rather minimalist list of standard features, and almost no driver assists, but who wants all that extra stuff getting in the way of the experience? As for a safety rating, that's all up to how you drive, since neither of the US roadworthiness organizations have put the 2021 Porsche 718 Cayman GT4 to review.

Everything about this car screams driver involvement, from the roaring naturally-aspirated engine to the way it clings in the corners and tells you exactly when it wants to let go. Many competitors make more power or have the potential to make more power thanks to turbocharged power plants, but there is nothing that comes close to the pureness you get to experience in the 2021 Cayman GT4, at least not in this price range. Porsche has created a legend.

🚗What 2021 Porsche 718 Cayman GT4 Model Should I Buy?

There's only one trim, so you'll have to look at the options list to make your GT4 a bit more unique. If we had the pleasure of buying one, we'd get one in Carrara White Metallic and get the wheels painted in Satin Aurum. On the inside, we'd opt for the full bucket seats. In terms of performance, we'd stick with the manual transmission but add the Chrono Package and ceramic composite brakes. Finally, we'd add the smoking package because you'll want a cigarette after a roll in the hay with this German. The total price of a 2021 Porsche 718 Cayman GT4 coupe with all these extra bits will set you back around $120,000, after paying destination fees.
