This is a very relevant and useful comparison. It's not the first of its kind either - various British publications have been comparing small, feist hatches with big, monster supercars for decades now. The most recent one prior to this I recall as being EVO pitching the WRX STI against the Lambo Gallardo in Wales and, before that, the M6 vs the Sport Clio II Trophy in France.
It's quite simple really. Fanboys and enthusiasts dream of owning the ultimate cars but, if you're really passionate about driver enjoyment, you'll soon realise that modern roads never test the stratospheric dynamics of a true supercar unless the driver is spectacularly talented (very rare - call Walter Rhorl to chaffeur-drive you around rather) or, much more often the case, completely ignorant. It's obvious then that the more grip and pace a car has, the wider the road has to be in order to exploit the car's handling capabilities. In narrow, real world roads, it's the smaller, lighter, less powerful car that gets the job done in terms of satisfying the driver the most. No, to truly enjoy the GT-R and GT3 et al to within their limits and beyond - you have to spend time on a circuit.
It's exactly this scenario that forms the raison d'etre behind the hot hatch genre. And also, it's precisely why a MINI Cooper S is such daft fun on public roads.
