Now I can't help but ask a question - which, out of arguably the two most exciting driver's cars of the moment, is the better car?
So let's knock off some of the detail stuff before drilling into the more subjective differences.
1 Which one is quickest? The Ferrari, but only just. If anything the GT3 feels stronger low down, but right at the very top the Speciale pulls hardest, and therefore accelerates that little bit more ferociously (which seems ridiculous to conclude when one considers just how manic the GT3 feels over the last 2000rpm).
2 Which one handles best? The Ferrari, I think. Why? Because its front end is that much more pinned (despite its the new four wheel steering system, the latest GT3 still understeers a touch in quicker corners), the Ferrari's rear end is every bit as well balanced, it doesn't have quite as much traction as the Porsche, but it does have a natty little trick up its sleeve called side slip control. Overall it's fag paper stuff separating them in isolation - mainly because they are so different from one another in handling character - but I'd still be prepared to give the nod to the Ferrari. Probably.
