Re petrol and mileage I do 34 miles a day Monday to Friday (170 miles total a week). My average mpg is 31-32 with motorway and urban en routes. I am a super economical nerd driver when it comes to mpg but I also like to put my foot down when the road is clear. I have got into the habit now of using normal mode for town (with the blue dashboard light telling me I’m driving economical all the time), sports for motorway when I’m laid back cruising and sports+ when I’m in the mood to be playful.
So 170 miles a week or 34 miles a day mixed driving, urban and motorway, average 31-32 mpg and averaging £43 per week with shell v power.
