So hats off to the delightfully crazy people of the Porsche Motorsport department who decided not to simply turn up the boost on the 2.5-litre four-cylinder turbo motor in the Cayman GTS until the requisite 420PS (309kW) appeared on the dyno sheet (which the engine would have taken with ease). Instead, it removed the turbos from the 911’s engine and both bored and stroked it out to 4.0-litres, which I think we can agree is going the extra mile.
What results is a car with less torque than a four-pot Cayman GTS and because of that and the fact you can spec a double-clutch transmission for the GTS, one that’s actually slower to 62mph than the GTS and no quicker to 100mph.
But if ever there were a car in which how fast it goes means nothing relative to how it goes fast, this surely is it. The engine is not savage – I expect we’ll have to wait for its GT3 application before we see that – but it is sweet and sonorous. And it makes you work: it won’t pull its hardest until 5,000rpm is on the clock, so you have to use that delicious gearbox to ensure you’re always in the right ratio, which is, of course, an entirely good thing. The more a car involves you, the more involving it will be.
Even so, and just like the 2015 Cayman GT4, the powertrain is cast as an entirely supporting role to the chassis whose suspension is modified almost beyond recognition compared to a standard Cayman, including borrowing the entire front end of the GT3. On the right road, driven with a commensurate level of commitment, the car is mesmerising. Grip levels on standard Michelin Cup 2 tyres are dazzling, the car’s balance, poise and accuracy sufficient to make normal sporting cars look and feel slow-witted and stumbling by comparison.
