I doubt we will see the NFGT being used to set track records all over, especially with how rare and expensive they will be. I sure wish they would because I feel it is going to be an incredible track car. The ACR is certainly a very capable "almost race ready" car for the street, but my money would be on the NFGT. I think this NFGT is going to be very different than what we have been seeing in other exotic supercars. This GT is being engineered and designed as a race car first. It is going to be light, really light. It will have better power to weight than the Viper and also the technology of a modern race car. Just the DCT will be good for a couple seconds a lap on most courses, and there is still much technology Ford hasn't even disclosed yet. I think the NFGT will not only be faster, but much easier to drive at the limit than the ACR. I think this car is going to surprise a lot of people with its performance.
Just my .02 :cheers
