How much gas is wasted when a 3200 lb car makes a stop on an incline?
A lot! lol Hard to say an exact amount, but basic physics tell
you that in order to get an object up a hill, it takes energy. If
you're already moving when going up a hill, you bring some energy
to start with as inertia, the engine then provides the rest of
energy required to get up the hill. If you stop, the engine is now
forced to create all of the energy required, therefore burning more
gas... It depends how big the hill, the degree of incline and where
you stopped on it, not to mention a hundred other variables. On an
average hill stopping 1/2 way, I'd say it would be safe to assume
that you've wasted 1/16th to 1/8th of a gallon of gas.
