True, mine usually says 600 odd so the behaviour (and smaller wheels for the meantime) has had an effect. I reckon it'll be more like 650 miles when the tank is empty.Meh. When i fill up my 3l 6 cylinder petrol bmw x5 45e it says 648 miles on a full tank. Will never happen.
I wasn't at the time when diesel cost £1.20 a litre, not the £1.76 it does now. There's no need for Sports mode when driving to work in tourist and caravan laden traffic at <60mph, no point at all. In the few opportunities to overtake then I have the ability to use the power available.Genuine question, but why did you get a 640d if you’re concerned with the cost of fuel?
