    I free wheel a lot otherwise I have to change gear a lot to cope with changing inclines, and slowing down for corners.
    I need an advanced driving test.

    Use the gears, or buy and Auto.

    The other option is get on some trackdays with someone who knows thier stuff, fun and educational

    dad has an auto, drives me nuts driving like a granny going through the gears. I will get some education though. Learner driver instructor lives at top of hill...
    ...quickly but safely as I am already late for tea and almost certainly in trouble...

    Don't go though the gears, just leave it in second and keep your foot down*

    *keeping within all speed limits obviously :tongue:

    I gain at least 15% improvement in fuel consumption by slowing from 70mph to 55...nowadays, if I don't have a particularly necessary arrival time (e.g. going home after dropping someone off at the airport), I just set 55 or 60 on the cruise control (which is also the most efficient way of driving, according to my on-board computer), and take my time.

    I used to coast in neutral until my son pointed out that it confuses the electronic management system which is there to optimise performance. Assuming my car's computer is accurate, by dint of really careful driving on long trips, I regularly get over 60mpg (record so far 69 mpg!). A 1.9l diesel, by the way.
    I agree about 56ish speed - really effective. An earlier point about taking two hours to drive 140 miles at 70 mph would save half an hour over someone travelling at a much lower speed. True, IF you can maintain an AVERAGE of 70mph - quite difficult if you don't want to break the law. In a forum like this, shouldn't fuel consumption and related emissions be of more importance than saving a bit of time? After all, most journeys are fairly low mileage and the difference over, say, a 35 mile journey in the same example would be a whacking seven and a half minutes, hardly time to get a leisurely drink. As the Americans should say, do the arithmetic.

    Yes, when coasting in neutral the EMS feeds in just enough fuel to keep the engine running; when on over-run in gear, the EMS knows that no power is needed so shuts off the fuel altogether. Unlike old (or present) carburettered vehicles, which are inacapable of shutting off altogether, but are set to supply enough fuel to tick over in neutral as a minimum, but might well draw more if the engine's turning over faster on over-run in gear.

    What I said on page 1. Depends if the car is fuel injected. Most modern engines are in order to meet emissions regs.
    The roads are dangerous places, we all agree on that I would imagine? Driving faster means we spend less time on them, this is a fact "and so I end the case for my defence officer".
    Sorry, couldnt resist.

    And more time in hospital, jail or grave :bigsmile:

    That means you spend more time parked up with increased risk of your car being stolen :devil:
