2025 Porsche 718

The Porsche 718 is offered as the Boxster roadster or as the hard-roof Cayman coupe, both holding two people and with engine variants ranging from 295 to 493 horsepower. While the German automaker had previously indicated that these would be electric-only by 2025, that hasn’t happened, and so it’s still strictly petroleum power this year.

Competitors to the 2025 Porsche 718

Premium and mainstream rivals to the Porsche 718 models can include the BMW Z4 and its sibling Toyota Supra, Lexus RC, Mazda MX-5, Mercedes-AMG GT Coupe, and Nissan Z.

What’s new with the Porsche 718 for 2025?

The 718 models are unchanged, except that the automatic dual-clutch – the PDK, or Porsche Doppelkupplungsgetriebe for those practicing their German – is now the default transmission in most models, with the manual transmission available as a no-charge option. As they did last year, the RS models come only with the PDK.

2025 Porsche 718 Performance

The entry Cayman and Boxster models use a 2.0L turbocharged flat-four-cylinder that makes 295 horsepower in the Cayman and 296 in the Boxster, along with 280 lb-ft of torque, and mated to a seven-speed PDK or a six-speed manual transmission. The Cayman and Boxster Style Edition models increase that to 300 horsepower but retain the 280 lb-ft of torque.

The Cayman S and Boxster S use a turbocharged 2.5L four-cylinder that makes 345 horsepower and 309 lb-ft of torque. The Cayman GTS 4.0 and Boxster GTS 4.0 use a naturally-aspirated 4.0L flat-six making 394 horsepower and 309 lb-ft of torque. The final steps are to the Cayman GT4 RS and 718 Spyder RS, which also use the 4.0L six-cylinder but take it to 493 horsepower and 332 lb-ft of torque; and these two only come with the PDK. All 718 models are rear-wheel drive.

In a review of the 2023 Porsche 718 Cayman GTS 4.0, Peter Bleakney said, “…the GTS 4.0 finds a sweet spot that perfectly straddles edgy, snarling performance with a disposition one can live with on a daily basis. This has always been the signature of Porsche’s GTS models — not the fastest, not the most expensive, but tuned and spec’d specifically for the enthusiast…the 4.0 goes from a somewhat gruff idle to a mellifluous midrange to an all-out banshee howl as your right foot plays conductor to this Swabian Symphony in G-whizz. Above 4,000 rpm, the GTS 4.0 goes on a holy tear. It’s a fast car, but not stupidly so — the perfect amount of power for the street.”

2025 Porsche 718 Efficiency

The Cayman and Boxster share their fuel efficiency scores, as per Natural Resources Canada (NRCan). The 2.0L with PDK is rated at 11.0 L/100 km city, 8.7 highway, and 10.0 combined, for an estimated annual fuel cost of $3,700. The stick shift rates 10.9 combined and $4,033. The S models with PDK rate 12.2 city, 9.2 highway, and 10.9 combined for $4,033; and 11.2 combined and $4,144 with the six-speed manual. The GTS with PDK rates 12.3 city, 9.8 highway, and 11.1 combined for an estimated $4,107; while the manual is 12.2 combined and $4,514. Of course, all of them want premium-grade gasoline.

2025 Porsche 718 Safety

As is common with low-volume sports machines, the Boxster and Cayman haven’t been rated by the U.S. National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS). Standard or optional driver-assist features include adaptive cruise control, blind-spot monitoring, and mandatory rearview camera.

2025 Porsche 718 Reliability

Consumer Reports gives the 2025 718 a predicted reliability rating of 50/100, saying it expects it to have “about average reliability” when compared to other new cars, based on Porsche’s brand scores. In the J.D. Power 2025 U.S. Vehicle Dependability Study, which looks at three-year-old vehicles, the 718 didn’t win an individual award, but Porsche as a brand ranked eighth among all automakers.

2025 Porsche 718 Interior

The 718’s cabin uses high-quality materials and controls that are generally easy to use. Porsche is known for offering numerous options so buyers can get exactly what they want; and to that end, these can include different types of sports seats, heated steering wheel, Sport Chrono package, premium stereo, and more than a dozen variations on interior accent trim and stitching.

In a review of the 2023 Porsche 718 Cayman GTS 4.0, Peter Bleakney said, “For those travelling two-up, the deep front trunk and rear hatch provide ample space for a weekend’s worth of luggage and some shopping. Sadly, the cabin has no storage space to speak of and the flimsy cup holders seem no more than an afterthought. I do like the fact that the cabin sports a plethora of good old-fashioned analogue controls and buttons — a reminder the 718 has been with us since 2016.”

2025 Porsche 718 Dimensions

The Porsche 718 has an overall length of 4,378 mm (172.4 inches). The front trunk has capacity of 150 litres (5.2 cubic feet), while rear storage is 125 litres (4.4 cu.ft.), so be prepared to travel light.
