Hello,
This was taken from FuelAcademy.com's Tips page:
"Drive Downhill in Gear
Driving down hill in neutral (free wheeling) you will use some fuel. When you drive down hill in gear (the safest gear under the circumstances) in a modern day car you will use NO fuel whatsoever"
I was wondering if anybody could give me an explanation on how this is true? The good aerodynamics of my new Jetta (as opposed to my old pickup truck) allows it to actually increase speed on most downhill slopes I go down (when I put it in neutral) so I would think that is the best way to save gas while coasting.
So how does that method use some fuel (of course the engine has to run) while leaving the car in gear (and not stepping on the accelerator I would assume) use NO fuel???
I'm still trying to maximize my fuel economy so any knowledged info from this great community would be greatly appreciated.
Thanks!
