Incidentally, every single test I've read of 1M vs. Cayman R has placed the Porsche out in front, even though it's not as quick and costs £10k more.
I do think that anybody in their right mind would expect both the Porsche and the Lotus to likely be faster around a track, seeing as they are mid engined, pure bred sports cars, instead of a semi-luxury coupe on steroids. That's why I added the "in a drag race" bit.
I still think it is a feat to beat cars that a) cost a fair bit more and b) aren't based on what's a rather sedate day to day car, whether it's a drag race, or not. It's the same as the M3, really. It's not going to kick the living crap out of pure bred sports cars, but it is fairly remarkable for what it is. And that's a relatively comfortable, roomy car with your usual FR layout. Nothing more, nothing less.
It's also worth mentioning that the Golf GTI cut into the sports car market because it was significantly more reliable than the British sports cars available at the time, too.
One of many reasons, yes. The point, I think, Clarkson was making was this one, though: While the 1M might not beat cars like the Cayman R or the Evora S around the circuit, it's fairly fast. As in, 'those cars won't destroy it' fast. The fact that the Cayman R and Evora S are competing with a car that's based on the 1 series is quite something by itself.
So, you're sacrificing a bit of your lap time so you can safe ten grand, have rear seats and a boot. That does sound a bit like the 'more room, more comfortable to life with, cheaper' bit that the hot hatches had over your average Biritish roadster, doesn't it?
