Which concept do you like better? I personally like the FR-S but with 3.5l 400hp in the FT-HS.

My point is not so much an electric propulsion engine as it is hosepower. It sure would be nice to have the option say a gt frs model with more hp than a 2.0 boxer can give. After all the the Ford Focus 2.0 echo boost puts out 250 hp. Do you really want a car that looks like a Ford "Focus" to be faster that an FR-S? That would be embarressing in my view.
