Porsche 718 Boxster GTS review – as good as the Boxster can get?

Sharper feel and extra power make the GTS the most entertaining 718 Boxster yet.

we'd still prefer six cylinders

GTS models have traditionally been a highlight of the Porsche model line-up, so we’ve been eagerly awaiting the GTS versions of the latest 718 Boxster and Cayman.

While you won’t find an extra pair of cylinders however hard you look – like other 718s, the GTS ditches the old flat-six in this generation – you will find an uprated chassis, a host of extra standard equipment and a useful power increase. Is the new Boxster GTS, like its predecessor, the pick of the standard range?

Engine, transmission and 0-100kph time

In the space between the passenger compartment and rear axle sits a 2.5-litre, turbocharged and dry-sumped flat-four driving the rear wheels through either a six-speed manual transmission or a seven-speed PDK automatic.

Likewise, torque increases to 310lb ft, spread in a plateau from 1900 to 5500rpm in the manual version, or 317lb ft up to 5000rpm for the PDK. The PDK is quickest of the pair on paper owing to near-seamless gearchanges, taking only 4.1sec to reach 100kph from rest or 3.9sec in Sport Plus mode, compared with 4.4sec for the manual. Top speed is a claimed 290kph in both versions.

Technical highlights

Engine aside, GTS tweaks include standard-fit Porsche Active Suspension Management (PASM), with a PASM sports chassis an option and one that chops 10mm from the ride height of GTS models (already 10mm lower than a Boxster S). Sport Chrono is also standard, with a Sport mode for the Porsche Stability Management (PSM) and a mechanical torque-vectoring differential. Cast-iron brakes are standard, with carbon-ceramics (denoted by yellow calipers) an option.

Twenty-inch Carrera S wheels are standard on the GTS, with a staggered tyre set-up putting 235-section rubber up front and 265s astern. In addition to visual changes wrought by the 20-inch wheels, GTS Boxsters can be identified by dark-tinted head- and tail-lights, revised front and rear bumpers with black detailing, and black GTS badging.

What’s it like to drive?

Our initial exposure to the GTS was not in ideal conditions. Southern Spain’s driving roads are fantastic when dry but treacherous when wet, and a recent thunderstorm had left a sheen to the tarmac that made grip completely unpredictable.

Still, there are few better cars in which to get used to such conditions than a Boxster. The GTS, like others of its ilk, relays some of the most detailed steering feedback you’ll find in an electrically assisted set-up. While there could always be more information, the subtle changes in resistance through the rim – combined with utter precision and near-perfect weighting – make feeling for the limits of the tyres as satisfying as it is necessary when the roads are greasy.

Oh, but for a more enthralling soundtrack! Objectively the tweaked 2.5 is hard to fault, with excellent responses for a turbocharged unit, and strong low- and mid-ranges that both effectively negate the bugbear of overly long gearing, and make the Boxster’s fantastic balance even more responsive to throttle inputs.

But while the extra power makes the GTS even quicker, it still won’t feed your craving for the kind of high-revs, high-fidelity tunes played by its predecessors. At low revs and under load it sounds like there’s a Massey-Ferguson on your tail, while the mid-range has more than a hint of Beetle. At higher revs you can just about kid yourself of some Impreza-style character but it’s a bit uncultured even for that, and the popping and crackling overrun in Sport is depressingly artificial – it’ll do so even if you’re pottering through a village at 2000rpm.

Price and rivals

As has become customary for the 718 range, the Cayman is the cheaper of the GTS pair with prices starting at $80,200. The 718 Boxster GTS begins at $82,700, and while the sensation of driving a car that handles this well with the roof down is hard to beat, there’s also something to be said for the Cayman’s ability to mute the unappealing flat-four noises…

Rivals? On talent alone, there’s little to compare. Perhaps the most intriguing is a car we should be driving very soon – Alpine’s new A110 coupe. It’s powered by a 1.8-litre in-line four, matches the Boxster and Cayman’s mid-engined layout, and is appealingly compact in the metal. Pricing is expected to begin at around $66,990, and no open-top Boxster rival is available for the time being.

One that does offer both fixed and open-roof variants is the Alfa Romeo 4C, in coupe and Spider form. The coupe comes in at $70,770 and the Spider at $80,140, and while they’re bustling with character and feel special from behind the wheel, the chassis and drivetrain just aren’t up to the 718’s quality, even considering our misgivings with the flat-four.
