Obviously each can have their own interpretation of what performance is but yours is pretty limiting, Hemi was more of a race engine in a production car, to me performance is when you have an excess of power more than what's needed to do everyday driving, where the line of peppy to performance car is ?
I have an old Toyota Corolla for a commuter. Love that little car. It has a **** ton of miles on it and still drives like new. I'm sure it would go 100 mph. More than enough for everyday driving. Performance car?
