Summary
The Porsche Cayman first appeared in 2005, effectively as a hard-top version of the second-generation Boxster cabriolet. The current model launched in 2016, when both the Cayman coupé and Boxster convertible gained the 718 moniker recalling a 1950s Porsche sports car. More pertinently, it also switched from naturally-aspirated versions of Porsche’s signature flat-six engine to mostly turbocharged flat-four units.
Mid-engined and cheaper than other models propelled from the rear, the Cayman is sometimes derided as a “poor man’s 911.” Reviewers are generally positive about it, however, though disappointed at the emissions-led change in engines.
Four power outputs are on offer ranging from 300hp of the regular Cayman to the 420hp of the hardcore GT4 model.
This and the GTS were launched after other Cayman variants, and saw a return to six-cylinder power. “They’re expensive,” says The Telegraph, but “these are the sort of cars about which you’ll remember the driving quality long after you’ve forgotten the price.”
Testers praise the excellent handling of the Cayman, so much so that the more recently introduced lightweight T model is not considered different enough to justify its price – “the standard Cayman is such a find-handling car that 90% of drivers would never sufficiently exploit the T’s chassis to notice the extra benefits it brings,” says Auto Express.
Some reviewers point out that the interior does not include the modern touchscreens of other Porsches, but others consider this a good thing. And it is regarded as a minor issue in a car with prodigious potency and exemplary handling – Top Gear describes the Cayman as “a fantastic sports car with a real breadth of ability.”
Reliability appears to be an issue for the Cayman. In a 2021 reliability survey, What Car? rated it as the third-worst new car on sale, with more than half of owners having problems and two-thirds of those having to pay for repairs themselves rather than being covered by the car’s warranty. This continued into 2022, with the same survey ranking it as the least reliable car in the coupé/convertible/sports car category.
As of January 2023, the Porsche 718 Cayman holds an excellent Expert Rating of 86% from 24 reviews. That’s exactly the same score as its convertible sibling, the Porsche 718 Boxster.

“The Porsche 718 Cayman GTS is a bit of cracker. It’s sharp, nimble and brilliantly suited to the UK’s roads – and it gets better the harder you drive it.”

“It may not look any different, but this new Porsche 718 Cayman GTS is a transformation – and the pick of the range. At face value, it may seem pricey compared with a regular Cayman S, but the extra cash is worth it for the new naturally-aspirated 4.0-litre engine alone.”

“The Porsche 718 Cayman looks a million dollars and, when it comes to handling and driving fun, sits right at the top of the pile. What’s more, its sublime steering, superb control weights and exceptional ride quality make it a brilliant long-distance GT.”

“Yes, it’s a four-cylinder 2.0-litre turbo and we’ll get this out of the way now: it doesn’t sound like naturally-aspirated flat-six – because it’s not.”

“The latest Porsche 718 Cayman GT4 remains one of the most impressive and enjoyable road cars to drive on a circuit, especially if you subscribe to the theory that less equals more, and value the way a car makes you feel rather than its outright speed.”

Score: 8 / 10
“The GTS polarises. It is expensive, it does not have a clear edge on performance, and the engine is no more refined than the lesser engines. On the other hand, it looks sexier, has a potentially higher resale value and when everything falls into place the 360bhp Cayman easily matches the 444bhp 911 in grins-per-mile.”

“We love the Porsche 718 Cayman. It’s a bit like Usain Bolt. Still brilliant and best in class – we just rue the passing of that super six-cylinder from yesteryear. We remember how much more sizzling Bolt was back at Beijing and London; but he was still at the top of the podium in Rio too.”

No safety rating
Neither of the Porsche 718 Cayman and Boxster twins have not been crash tested by Euro NCAP, and we’re not expecting it to happen anytime soon. If it does, we’ll include the results here.
No eco rating
As of January 2023, the Porsche 718 Cayman has not yet been lab tested by Green NCAP. Given that the Cayman is a high-performance, petrol-engined sports car that prioritises performance over economy, it’s unlikely to win any environmental awards…
