Does this apply as much to hybrid-engine cars? I heard that the percentage
of difference between "real world" mileage and EPA numbers was much greater
with hybrids. For example, a Hybrid rated at 38 city, 50 highway might see
real-world numbers consistently in the 36 range, while a traditional
gas-engine vehicle that also sees real-world numbers consistently in the 36
range would be more likely to be rated at, say, 33 city and 42 highway.
If this is the actual case, does it mean that the mileage of hybrid-engine
cars drops off more sharply under non-ideal conditions than that of
From what I've read about hybrid drive vehicles and heard from friends in
the automotive industry, fuel economy in hybrid vehicles tend to be better
in an urban stop-and-go environment than on the highway. This is because
the internal combustion (IC) engine is less likely to be running at lower
vehicle speeds and the regenerative braking system returns some power back
to the batteries versus on the highway, where the higher speeds mean the IC
engine is running and there is less regenerative braking.
Having heard from people who say that they get as good as or better fuel
economy than the EPA estimates and people who say that their mileage is much
worse, I suspect that driving style and environmental conditions has a
greater effect on fuel economy on a hybrid than in a conventional
correct the return address punctuation to reply
Like all the posters are saying: Driving style effects fuel
consumption. My father consistently gets 10-20% better than EPA
regardless of the vehicle he's driving HOWEVER. He uses a block
heater 60% of the year so he's never starting a cold car, His brakes
are usually original when he trades a vehicle in near 100K & he will
often shut the engine off and coast when on hills & approaching
traffic lights or traffic jams. (This might play a part) His tires
also last close to 60 K as well.
Some Hybrids (I won't mention Toyota Prius here) seem from what
everyone says, do consistently worse than rated. Others (I won't say
Honda Accord) do pretty close to their rating.
My 1995 Olds 98 Regency Elite will hit High 30's driven sensibly in
the summer. Parked outside in & driven in the city during the winter
I'll hit high teens.
Vehicles are societies tools of consistent consumption. If we lived
in a non-capitalist, non-consumption based society fuel economy
wouldn't matter b/c we'd all be walking through the snow or waiting
and taking subways/trains everywhere. However our society is based on
consumption. Oil is high to justify drilling in Alaska and processing
the Trillion Barrels of in Alberta before people move on to another
fuel source, so lets quit worrying about EPA ratings.
As my brother said after a serious car accident. "Fuel is a hell of a
lot cheaper than hospitals, buy a safe car".
EPA is just a rough guideline. I wouldn't base my purchasing decision
on what a group of overpaid under worked government officials say to
the public , After all what are they driving? ;-)
