That makes me feel a little better, as I am currently getting around 42mpg. I have done over 650 miles, I try to get up to speed,take the foot off, and then just use the electric power, longer breaking etc but struggle to get much above that at the moment. I do find the petrol engine very keen to join in, so maybe there is a difference between models. I do drive predominantly on motorways, is that bad for fuel economy, would I be better off taking a roads instead!
