It doesn't feel "big" like a Camaro or a Challenger but, it is a relatively big car. Hell on my Fox, I could reach over and open the passenger door without leaning. Cars are big/heavy because of safety and what people expect to be in them n terms of luxury and conveniences. The suspension is better on the newer car, taking away some of the ponderous nature of the New Edge car, which makes it feel more agile.
Your 2011 is a slick tire and mild tune away from 11 sec 1/4s so, other things are a lot better too.
