The whole AMG lineup is rumored to be making the switch to electric, so I would count on many of their high end sports cars to enter this category. Every automaker seems to have bold plans to build the best electric sports car, and it'll be interesting to see who can deliver the best bang for your buck. Don't forget the extremely high standard that Tesla has set, and the rumored specs of the new Roadster will be hard to surpass.
I hope with that move we see more affordable sports car shows up, and I mean real sports cars. The AMG GT is one of them, but could use a lighter and more driver focused sports coupe with an electric powertrain.
