So what is it about the Porsche Cayman GTS that is so completely and utterly compelling? Why is it so different to drive from the already very good Cayman S model on which it's based. And is there anything Porsche can do to better it for the rumoured forthcoming R version of its beloved coupé?

The reason it's so compelling, I think, is because it somehow manages to mix such ultra-sharp reactions – be that to its throttle, steering, brake pedal and even its clutch pedal – with a quite extraordinary level of handling forgiveness.

It stops for, turns into and goes around corners with the precision of a competition car, in other words, yet still it manages to feel friendly and approachable and not in the least bit edgy near the limit. And that's a rare if not unique combination for a car that's built to be driven on the road, in my experience.
