This year meaning GT500s MY12, but thanks for reading my post. That slight increase was a combination of PTWA and ESC and could be underrated by 1% (or roughly 5.5HP). Both technologies are becoming standardized and applied to Fords Halo car first. TiVCT incoming..
And that's a very nice car your driving...
