==Engine braking vs coasting==
I am tltoaly wowed and prepared to take the next step now.
In my V6 [[1997 Passat GLX]] I found over the years that engine braking got me better mileage than idling during braking. When I started driving a 1999 [[Audi A4]] with a smaller, turbo-charged engine, I found that idle sipped so little gas that it often was better to idle than to engine brake in it.
 
Now that I live in hilly Ithaca, with a [[2007 Passat Wagon]] I have found that the choice of methods of braking depends on the speed and the slope of the hill.
 
In all these cases, the car has had a manual transmission, and I have used the on-board mileage computer to help with the studies.
