Cayman 718

Porsche 718 Cayman GT4 et Spyder – TECHNO : l’évitement émotionnel

Un “flat-six” atmosphérique d’une cylindrée de 4.0 évoque forcément quelque chose aux plus porschistes d’entre nous. Oui, ces quelques caractéristiques affichées par la mécanique des 718 Cayman GT4 et Spyder rappellent furieusement celles d’un autre monument d’ingénierie : le fantastique moteur des 991 GT3 et GT3 RS. Mais ces deux six-cylindres n’ont pourtant pas davantage en commun.

Si celui des plus exclusives versions de la 911 puise ses origines au cœur de la compétition, l’autre, nouvellement venu au sein de la gamme 718, dérive du 3.0 biturbo de la récente 992. Bien qu’à la recherche d’une motorisation dépourvue de toute assistance respiratoire dans le but de favoriser les sensations de conduite, les ingénieurs de la firme de Zuffenhausen se sont en effet basés, de manière assez surprenante, sur un bloc doublement suralimenté.

Porsche s’est ensuite évertué à le débarrasser de ses turbines et de ses échangeurs. Ce qui n’est pas une mince affaire quand il s’agit de viser une puissance de l’ordre des 420 ch tout en satisfaisant des normes anti-pollution toujours plus draconiennes. C’est pourquoi ce nouveau 4.0 multiplie les raffinements.

Can Porsche’s 718 Cayman GTS Keep Up With Toyota’s New Supra?

In a word, sorta.

Thanks to this short video from the Carwow folks in the UK, we can see the comparative performance of a quartet of sporty performance cars. The two true Germans, Porsche’s 718 Cayman GTS and Audi’s TT RS Roadster stack up against the BMW with a Toyota hat, and a tuned version of the French Alpine. These cars are run through paces in quarter mile drag racing, a roll race, and a braking distance test.

I would argue that the wrong 718 was used for this test, as a base Cayman with 300 horsepower is priced almost identically ($56,900) to Toyota’s Launch Edition Supra ($55,250). By using the GTS model, which starts at $80,700, it’s not exactly a fair comparison. But I digress.

The GTS came in second in the quarter mile test, just a smidge after the much lighter Alpine. The roll race and the braking distance test were won outright by the incredible Cayman.

While the Supra didn’t quite pip the Cayman in any of these tests, it was within a margin of error to be certain. Any sports car that runs the quarter mile in around 12 seconds is properly quick. It’s clear that Toyota (and BMW) benchmarked the Cayman in the construction of the Supra. If the right priced base Cayman had been the one used, it likely would have been trounced by the Toyota.

It’s clear that Toyota has a good car in the fifth-generation Supra, but is it enough to drag you away from a Porsche?

718 Cayman GT4 Put Through Its Paces at Knockhill

More power, more aerodynamic grip, more performance, and more usability—we’ve heard all of the new Cayman GT4’s strengths already. However, few automotive journalists can test those claims like Steve Sutcliffe. Though he might not look like a superlative athlete, the man is arguably the best driver among his peers. Ten years ago, he was given the chance to test a Honda F1 car, and was only several tenths off James Rossiter, the Honda test driver roughly half his age.

Here, Sutcliffe uses all his strengths to illuminate the incremental changes that make this car 12 seconds a lap faster around the Nurburging than the 981 GT4. Despite the car weighing 80 pounds more and retaining the same frustratingly long gear ratios, the 718 is still quicker in a straight line.

Watch how urgently the car fires off the corner at 4:38. There’s an easily accessible engine at work here.

Based upon the motor found in the rear of the latest Carrera S, the 718’s new 4.0-liter motor makes 414 horsepower and 309 lb-ft of torque. Though that latter figure is the same as with the outgoing 3.8-liter engine, the added displacement provides a broader powerband, which helps camouflage the car’s long gearing. With the driver more often in the optimal rev range, the new chassis is more easily exploited. 

The steering, brakes, and suspension are closely related to those found in the GT3, and Sutcliffe immediately recognizes the changes. That sharpened steering is a real asset through Knockhill’s blind entries, which Sutcliffe attacks with the commitment you’d expect from him. 

A big rear wing, an underbody diffuser, and a bigger splitter creates 269 pounds of downforce at 188 miles per hour—nothing to sniff at. Not only is this car more incisive, but added stability—a little extra composure is always nice over the crests—is another feature which goads a driver to push that much harder. 

The improved powertrain, better composed chassis, and better exhaust note make it even more thrilling to drive than its predecessor, which was a firecracker itself. Incremental changes in every department make the new 718 Cayman GT4 a dependable, confidence-inspiring car which can soak up bumps, stay on the pipe, and encourage the driver to attack. That combination of qualities—not just the bump in power—is what is responsible for its incredible 7:28 lap around the ‘Ring.

Incidentally, that’s the same as the lap set by the 997 GT3 RS 4.0. Though tire technology has come a long way in ten years, having the least expensive member of the GT family set the same lap as the former heavyweight is a testament to Porsche’s unyielding search for incremental improvements in every department.

Composure, mid-engine balance, and great engine response—what’s not to like?

A Straightforward Take on the New 718 Cayman GT4 and Boxster Spyder

Smaller than a GT3, the GT4 is more easily placed on the road and track.

A motoring journalist worth their salt ought to verge on being salty. Fair judgement and an understanding of what a sports car should offer is what Dan Prosser brings to the table, and through his sharpened lens we learn how the quickest variants of the 718 lineup differ from their predecessors.

Since most YouTubers attention spans are limited and the cars are so similar, Prosser chose to drive the cars in the domains they’re better suited to, which revealed some interesting differences between the two. While Cayman GT4 showed more civility than its predecessor on the track, the Boxster Spyder was a harder, more focused machine for the country road. It seems the two are nearing a happy medium to keep the track rat pacified and the sunday driver excited.

Better for the Boulevards

The newest Cayman GT4 seems less of a skunkworks product this time around. Despite the rack losing some of its three-dimensional feel, it compensates with more composure and reassurance across cambers, pockmarks, and crests. At the end of the day, it’s still an incredibly accurate and intuitive car, but it pays for its poise with a loss in feel.

That is only one of the traits which helped this generation of the Cayman GT4 cover the Nurburgring twelve seconds faster than its forebear. Factor in less drag, more aerodynamic downforce, and a bit more power, it’s easy to see how a driver would feel confident pushing it hard on a varied and unforgiving track. It’s much friendlier at the edge of adhesion, thanks in part to a Porsche Torque Vectoring limited-slip differential which allows the driver to lean on the car. In short, it’s a more amenable car with better stats. For everyone but a hardened racing driver, that means its faster in most places.

Closer to the Right Compromise

Compromise might be the operative word with these two, since both still show a few shortcomings made in the name of everyday civility. Those frustratingly long gear ratios, a muted exhaust note, diminished steering feel, and a stowable top in the case of the Spyder mean that they’re not quite the hardcore motorsports product that they’re sometimes billed as.

Few cars allow its driver to soak in the scenery while driving quickly as this one.

This might seem harsh considering the beauty and craftsmanship of these two gems, but a discerning judge helps make the the avid driver more informed and less frustrated. Let’s just be thankful these two didn’t hold on to the four-cylinder turbo.

Despite their shortcomings, it’s hard to argue with the obvious purpose on display here. For those who want a little more from their mid-range Porsche without spending GT3 money, these are alluring alternatives. Plus, with their mid-engine balance and comparatively lower power, they’re much more approachable for the hobbyist than the hotter-blooded GT3 is.
