It was the victim of its speed.

I'm running in the low 50s using 90/10 gas/ethanol blend.

In the Consumer Reports original article, they did their math wrong. It
looks like they corrected the online version, at last.


From an earlier posting 21 days ago:

http://www.fueleconomy.gov/feg/fe_test_schedules.shtml

City: Represents urban driving, in which a vehicle is started with the
engine cold and driven in stop-and-go rush hour traffic. The driving
cycle for the test includes idling, and the vehicle averages about 20
mph.

Highway: Represents a mixture of rural and Interstate highway driving
with a warmed-up engine, typical of longer trips in free-flowing
traffic. Average test speed is about 48 mph and includes no
intermediate stops or idling.

My trick is to maximize my City MPG by driving a fuel efficient city
route and speed:

Scroll down to the route map to see the change. Also, note there are
some speeds that should be avoided.


Back in early January, I had just finished 3,000 miles but didn't get my
hypermiler star. I looked at the data and realized my very first entry,
my very first 251 miles at 75+ MPH had an MPG of 39 MPG. I verified that
MPG on another, shorter segment. So I asked the community if I could
drop just that first tank. Their answer was 'NO we must have all of the
data.' So the data remains:

I got my hypermiler start three weeks later, the end of January. But
apparently I am one of the folks who "fudge their figures" inspite of
the "bad" data being still in the hybrid database.

It is easy to toss out accusations that the GreenHybrid.com posters are
just lying but I would observe that most folks are not getting EPA
numbers and STILL reporting their numbers. They are not claiming as good
as the EPA sticker yet their reward for honest reporting is "fudge their
figures."


I've made a study of the Prius and found what works and what doesn't.
Because of this my most fuel efficient route is also the shortest, 9.8
versus 13 miles. The shorter distance compensated nicely for the slower
speed so my commute time has not changed.


We have it in Huntsville too.


You are free to look over the FAQ and see if maybe you can do better:

Some - okay, maybe all - of the problem is I never fall in the 55 mph range
on the roads I drive on.  More like 65 to 80+ mph speed which takes a toll.
Don't know if I'd ever get into the pulse/glide thing to maximize the mpg.
I'd probably fall victim to some road-rage Dodge driver.

I fear this week's northbound I-5 journey will put me under 40 mpg, maybe
more like 38 mpg range.  Traffic hustlles in the boonies on that road and
I've been passed at 90+ mph.  If I can remain locked on cruise, I may get 40
mpg.  I-5 must be some secret U.S. autobaun I haven't yet read of.  The
trucks seem to know the CHP's shift and eatry breaks in the early am and
will run you over.

Hwy. 95 in Nevada is another "I can't drive 55" place.  Talk about desolate.

I guess I'm doomed to getting in the lower 40's short of driving at less
than flow-of-traffic speeds.  I've turned the screen off as it gets
depressing seeing 38-43 on the screen when I read of everyone elses's
numbers.

Which year Prius? With my 2003, NHW11 model, the key is to avoid driving
faster than 70 MPH. Also, look for large vehicles to follow, not
tailgate, just follow. They also tend to hold steady speeds other than
on hills.

There is evidence that the transaxle oil has a significant performance
impact. How many miles do you have on it?
 

I don't use it beyond coasting up to lights. It really is a slow-speed
technique.


If you drive segments of ~2 hours long, you might consider using cruise
control and start plotting your MPG vs. MPH. Once you have your vehicle
performance curves, you can get some mastery of the game.

BTW, some of us are looking at making our own underbody pan out of heavy
duty, sign plastic, coregated stuff, coroplast:

Good luck!
