Is there any reason why a 600-hp twin-turbo V-6 would not fit in a Mustang engine compartment?
“I’m sure somebody could find a way to fit a twin-turbo into a Mustang, but we’re pretty happy with the 5.2 V-8 we’ve got in the 350 now,” Nair said. “It’s quite an engine.” He disputed the idea that the engine has reached its horsepower limit and cannot compete with the Camaro ZL1. “You know what they say about internal combustion engines—that they are always at the end of what they can do—and somehow we always find a way to do a little bit more. I think we still have a little bit more life in that engine.” As for the idea of competing with the ZL1 with a V-6 when muscle car buyers love their naturally aspirated V-8s, Nair said that might be true for some buyers but not all. “I think we’ve shown with our EcoBoost technologies, in the F-150 and in the Ford GT, that you can deliver the performance and the technology, and they appreciate it.”
