Last week I was up at Silverstone, talking to some loyal readers, attempting to explain to them why the new Porsche Cayman S that I’d been so completely blown away by just a couple of days previously, is as fantastic as it is. They wanted to know how and why, basically, it could be so much better than the previous model, which was in itself more than a little bit tasty.

So I thought about it for a while and then replied; “Two reasons mainly. One, Porsche claims it’s 40 per cent stiffer than before, and that’s phenomenal. Two, at the same time it’s 30kg lighter. And actually there are three reasons, the third being the PDK gearbox that was fitted to the car I drove, which is 110 per cent incredible in what it does.”

One of them, an engineer by trade, had actually driven a previous-generation Cayman not long before, and he simply couldn’t believe that the new car could be 40 per cent stiffer than the old. But the thing is, Porsche doesn’t just make this stuff up. Were the latest Cayman’s shell to be a mere 39.4962 per cent stiffer than of old, then that’s precisely what it would claim.
