My daily commute: Hypermiling vs. Not

those are some incredible mpg's! you're no bob wilson, but you're getting there!

 

Try to get those numbers on your gen II.

 

Intereating numbers !!! What changes in the afternoon that accounts for the much higher MPG ???

We pretty well stay at the posted speed limit or a bit above (65-75) in traffic, so our average is Mid to high 50's depending on wind and other conditions. We get into the low 60's when conditions allow.

Best to date was on an aprox 30 mile drive through a state park. Max speed limit was 35 mph with lots of slow gentle driving. We filled up just before heading into the park and did a "Trip A" reset at the gate.

Indicated MPG edged up to a final high of 105 MPG at about the 7/8 route mark, but backed down to 95 by the time we climed the last several miles back to the gate. Could this have been an accurate number caused by the very gentle slow drive, or was it a glitch in the trip computer ???

 

Elevation. Downhill does better than uphill.

 

Yes that is a big one.

My commute has very little elevation change the biggest being a bridge about 125 feet but that is the same both way other wise less then 100 feet perhaps.....

My afternoon return is always better on normal days ... which I attributed to warmer air and at work I park in a garage which is kind of heated. Engine warm up cycle is finished before exiting !!!

 

Been two years, but I thought I remember the 3 digit mpg number on the "trip A " read out . Am I mistaken that the trip A readout can display 3 numbers plus 10ths ???

 

thanks bob, that's what i'm talking about!

 

Stop me before I hyper mile again!

You probably can't help but hypermile vs. "normal". I'm guessing the 59.5 average is our Scangauge miles which would translate to 62.5 mpg on the Toyota gauge.

I don't think it is possible to get 62.5 mpg from a 50 mpg car without a lot of hypermiling. Even at 59.5, it would take a fair amount of working it to get 20% better than rated mileage.

Plus don't you have 17 in wheels which cut into the base 50 mpg rating?

Probably after driving a Prius for a while, the training effect is such that Prius drivers can never drive "normal".

I did discover that using EV mode at stops, I'm faster away from the light than big Diesel pickups so we are no more annoying on EV mode than the big rig Diesel pickup good ole boys.

 

I have the same elevation change for my commute. Charging at both ends I get 80 mpg going up and 300 mpg return.

 

You did note that you were going at the speed limit for normal driving and 5 mph under when hypermiling, what was your average speed on the whole commute? I think that speed is a very big factor, maybe even bigger than your hypermiling technic.

 

Before 2008, the EPA Highway label figure was simply the CAFE highway test cycle measurement discounted by 22%. A driver who matched the highway test profile could expect more than 20% over the EPA label.

Since then the formula has become more complex, weighting in some additional tests, producing a deeper discount from that old highway cycle. But the test numbers are published, and cwerdna has frequently posted the link to those results. The 2010+ Prius liftback tests out a hair over 70 mpg on that basic highway profile.

 

when I go to my parents house 240 miles away I set the cruise to 62 and get around 64-65 mpg depending on outside temp. no hypermiling on the highway just straight cruise control. it is rated at 48 on the highway.

on vacation my wife and parents loaded up my Prius drove 13xx miles cruise control at 77 mph on the 70 mph zones no hypermiling and mountain driving (we went to the smoky mountains and lookout mountain) still got 52.x mpg for the trip just driving like a normal person with AC, left the AC on when in parking lots, etc and high mph. these things just perform.
