I just wan't to talk about incredible feats of FE. Such as +100mpg in a metro of +150mpg in a honda insight. I undersatand that this is only a acheiveable in near perfect conditions.
So, that is the best way of doing an insane mpg section? This is what I figure you need.
-Warm outside temps.
-Low or nearly no wind.
-Low speed pulse and glide (i have noticed average speeds are in the 20s or 30s. so is the a p&g between 4th and 3rd gear).
-Nearly flat road.
-Low traffic (or no traffic).
-High tire pressure.
I wonder how much better the FE would be if it would be tested on track (such as a large oval).
2008 EPA adjusted:
Distance traveled by bicycle in 2007= 1,830ish miles
Average commute speed=25mph (yes, that's in a car)
Buy yourself a nice big science lab with wind turbines, climate-control, a treadmill for the automobile, and lots of computer equipment. Make sure the interior walls are painted Titanium-White for best effect
Driving in the middle of the night seems to work best for me. The traffic lights are easier to predict and there's no people to run you over if you do 40mph (or less ) on the freeway.
So, that is the best way of doing an insane mpg section?
The discipline and restraint to accomplish such feats is the one thing I most lack. Of course, a lot depends on the length (both the distance and the time) of a 'section'. The longer the 'section', the more mental preparation is required. I just relax and drive while I listen in on the conversations between the voices in my head.
Now that you ask, I guess height isn't really an issue. It's more about grade. Height becomes an more of an issue when the grade isn't ideal (e.g. if you have to go up an extremely steep hill that has the engine working way outside its minimal BSFC zone, you want it to be a short climb ).
I wonder what's the "ideal" hill profile...
EG for the downgrade, it seems like you'd want something that goes on as long as possible with a terminal coasting velocity of roughly 40-45 MPH (so you're not burning up too much kinetic energy on wind resistance).
My best test loop segment was 70 mpg in the Civic. One of my test loops is semi hilly, good in the country two lane asphault at 20 miles long round trip. Temps in the high 80'sf. No wind. My ave. speed was 27 mph.
My reason for doing the test loop that day was to see the diff. between doing the loop with no fas'ing and with fas'ing.
No fas'ing and on a cold engine was 60 mpg @ 27 mph.
fas'ing was 70 mpg @ 27 mph.
