No ones compared them directly on track, and seeing as though theres only 0.4 of a second difference between them on the TG track i would think they're on track performance is fairly similar. Yes its got alot more torque but that doesen't really matter as much on a race track and theres numorous accounts in magazines of the CS being an excellent road car.
In favour of the GT it has exclusivity and an engine built in britain
But the CS has one of the greatest if not the greatest sounding engines and probably a marginally better chassis, theres no doubt i'd take the CS
And as people have said, the 360 is a 5-6 year old car and we're comparing it to a brand spanking new Ford GT, lets see how the F430 compares when it comes out.
