Thought I'd read somewhere that coasting in neutral was not such a good idea as you were still using petrol, where as if you left it in gear, granted it would have to be a high one to coast, the engine shut off the petrol or something like that?.....
Clarkson said if you depress the clutch and coast then modern cars don't use any fuel. Not sure if he was referring to the Z or just some frugal BMW 1 series where the car runs off the smugness of the toad sucking vegetarian driving it.
Jay, I drive like a knob and get 24mpg. Changing your driving style is prob easier than getting a gay BMW
