The CarGurus verdict

One of the best real-world performance cars on sale today. Some will find the tuneless four-cylinder engines in lower-spec models intolerable, but the majority of buyers will think their flexible, torque-rich performance more than makes up for an uninspiring soundtrack. Meanwhile, the high-revving six-cylinder engines fitted to the GTS 4.0, GT4 and GT4 RS, while not without their flaws, are among the most evocative sports car power units in the sub-£100,000 price category.

Engines aside, all 718 Cayman variants are supremely capable and enormously enjoyable sports cars. As well as being fantastic to drive with great steering, delicious balance and limitless poise, they offer surprising practicality. They’re built tough, too, all of which means the 718 Cayman hits all the right notes whether you’re after a weekend plaything, a track day toy, an everyday sports car or your first Porsche. It’s all the mid-engined sports car you’ll ever need.

The Porsche 718 Cayman is a near flawless sports car. In fact, it can only really be faulted in two ways. The first is that the turbocharged four-cylinder engines that power entry-level variants are not the soulful, characterful motors you’d expect of a Porsche. The second is that all models have unusually long gearing, which is particularly frustrating in cars with manual gearboxes.

Those two shortcomings aside, the 718 Cayman has it all – great styling, usability, desirability, badge appeal, performance, handling precision… It is as complete a sports car as any on sale today. With highly-equipped and well-appointed cabins, they are effortless to live with (as long as you need no more than two seats), while two stowage compartments give the 718 Cayman more luggage space than appearances might suggest.

There’s also a fairly wide range of versions on offer, from an entry-level 2.0-litre model through to the raw, thrilling and track-honed GT4 and GT4 RS. None are particularly cheap, but strong build quality, excellent residuals and five-star driving experience mean the Cayman feels like it’s worth every penny.

  • Porsche 718 Cayman engines range from flat and tuneless to soulful and exhilarating, so it’s worth knowing exactly what you’re looking at. The base model, the 718 Cayman, uses a 2.0-litre flat-four turbo. It develops 296bhp and though it’s the smallest engine in the line up, it delivers plenty of performance. The 718 Cayman S also uses a turbocharged flat-four, but it produces 345bhp and displaces 2.5 litres. Neither one sounds especially pleasant, but the bigger option is a fraction more tuneful.
  • If you want a naturally-aspirated flat-six in your Porsche sports car (and who wouldn’t?), you’ll need to spend more. From 2020 onwards, a 4.0-litre unit was offered in the GTS 4.0, It develops 395bhp and has the kind of free-revving character you can never replicate with turbos. The hardcore 718 Cayman GT4 uses the same engine, but with power lifted to 414bhp. Joyful though these 4.0-litre flat-sixes unquestionably are, the need to fit environmentally-friendly gasoline particulate filters in the exhaust system does muffle their soundtracks to some degree.
  • Along with all the usual paint colour and interior trim options, most Porsches, the 718 Cayman among them, can be upgraded with all sorts of additional extras that will materially influence the character of the car. The dual-clutch PDK gearbox, for instance, costs £2000 and brings quicker gearshifts and keener acceleration than the manual transmission, but it also removes a layer of interaction between car and driver. Other items on the options list include adaptive dampers and a torque vectoring limited slip differential at around £1000 each, and carbon ceramic brakes at upwards of £5000.

  • On a budget: the 718 Cayman replaced the 981-era Cayman in 2016. It’s therefore been on sale for several years, meaning the earliest cars have slipped in value quite significantly. An early 2.0-litre model can now be yours for around £32,000. It will have covered 30,000 miles or so.
  • Must be brand new: the line-up starts with the £45,000 718 Cayman. You’ll pay around £54,000 for the more powerful 718 Cayman S, a sizeable leap in price for an additional 50bhp and some extra kit. Very few brand new Porsches leave the showroom with no optional extras whatsoever, so expect to pay more than these list prices.
  • The sweet spot: many commentators have described the 718 Cayman GTS 4.0 as the sweet spot in the range, because it features the howling 4.0-litre flat-six engine but is far easier to live with day-to-day than the uncompromising GT4 and GT4 RS. All that lets the GTS 4.0 down is its very long gearing.
  • No holds barred: the daddy of the line up is the 718 Cayman GT4 RS. It’s a ferocious, track-ready sports car, although if you’re willing to put up with a brittle ride and tyres that aren’t at their best in the wet, you could live with a GT4 RS every day. Just. One of the great modern performance cars.
