The single biggest change for the Boxster when Porsche turned it into the 718 was in the engine bay. Gone are the old six-cylinder engines, having been replaced by a pair of new four-cylinder turbocharged units. The standard car gets a 2.0-litre, but although the figures suggest it’s faster than before, it’s actually rather disappointing. It’s very over-geared – in the pursuit of efficiency – and that means it feels surprisingly sluggish at anything below 2500rpm. In fact, you have to be spinning it at around 4000rpm before it really wakes up and delivers the sort of pace you expect from a car like this. The S and GTS model have a larger 2.5-litre engine in two different states of tune, and this version is much more like it. Yes, it does also suffer a wee bit of lag, but it’s nowhere near as bad thanks to a more sophisticated turbocharger, making its performance much more eager and accessible. As well as getting into its stride quicker, this engine also punches much harder and faster, zinging all the way round to the 7000rpm redline. It feels especially quick when paired with the seven-speed automatic gearbox, which provides rapid, precise and instant changes, but the six-speed manual is also thoroughly enjoyable to use, with a precise action and meaty clutch. Where both engines struggle, though, is on refinement. Neither sounds as spine-tingling as its six-cylinder forebear, with the kind of synthetic bark you expect from a hot hatch, not a true-blue sports car. You’re also subjected to a collection of irritating resonances and booms, not to mention vibrations coming through the controls. That said, it’s not bad enough to ruin the experience, especially in the S and GTS, which is much quieter and smoother than the standard Boxster.
