I was thinking the Evo FQ440, because Mitsubishi, but I feel it's underpowered on the straights (347 less), even if the Evo is more maneuverable and more agile than the Dodge. So, new NSX? Has about the same power as the R35 Nismo, but I expect to be lighter than the R35. And I'm certain an upcoming NSX-R will be lighter than the 'Nilla NSX (3600 lbs).
But yeah. Challenger Hellcat vs. Evo FQ440. On Suzuka, Road Atlanta, and on Stelvio Pass and Transfăgărășan Highway Oh, and have a gravel rally stage, too. For the lulz.
