Actually I miss the friction. The F20 116i has very weak engine braking torque. When going downhill, even in second gear, it will roll almost all the way up to the redline before it stops accelerating, and then I'm already over the speed limits. It is supposed to regenerate energy by charging the batteries, but it is not even noticeable. I would like to have some electric motors in the car to generate some real braking power that can be used next time I want to accelerate.
