I don't think it's a particularly fast car, but then that's part of the reason I chose it in the first place. My previous car was just too fast for the public roads really and whilst it was decimating on track, you simply couldn't use all the power effectively when driving around normally. Personally speaking, I find that the Zed has exactly the right amount of power to remain totally useable on the roads, either motorways or country lanes.
Put your foot down in the right gear and will move along at a fair rate of knots, but it's never feels like it's going too fast to kill you.
