Anyone have start stop in Europe that can chime in on the use and actual fuel gains? Also what is this brake regenerating feature? All have this or is this a EUR thing as well?
I have to say that the mileage is horrible coming from an e46 M3. I enjoy the car but the mileage is no better than my old c55 with a 5.4l so how is it that efficient? Just because it makes more power with less liters?
