BMW X1 xdrive 2.0 petrol, only done 300 miles in it so far and averaged 36mpg with the heating on high most of the time, sure it will get better as it runs in, first petrol car I have had in 12 years, but only got a best of 43mpg in the pug 3008 1.5 diesel which has just gone back, and adding in the cheaper petrol cost and not having to buy ad blue every month may not end up being that much worse on running costs
