Kind of they did this back in the 80's with the Thunderbird and Mustang with the SVO 4cyl turbo. I think its cool but still a Mustang or Camaro with anything other than a V8 just isn't what I would think of.I can see it, but I REALLY like the side profile of the new Mustang. It looks like a huge step in the right direction, and I love that it is losing weight too.
And the current Mustang has a 4 banger also, its a new world.
