[QUOTE="Stereophile, post: 71743, member: 1344"] Fuel economy, on a car that is running well, comes down to physics imho. There is a large cost in energy to accelerate, and you have a choice of accelerating less, or, once you've accelerated, conserving the energy you've used by staying at that speed. Braking is a waste of the energy you've just used to achieve a given speed. Driving style makes such a huge difference to fuel economy, I think the other things pale in comparison. At my previous job we had different people driving the same cars, and we saw fuel economy, which was worked out monthly, of between 11l/100km and 18l/100km on the same vehicle but with a different driver for the month! :o That is like the one guy driving an 1800 and the other a 4 litre V8.
