high mph then glide
 
Has anybody try like for example. Your cruising along you hit lets say 70 mph. Then glide for as long as you can till you hit like lets say 45 mph then accelerate back up to 65 mph or 70 mph then glide some more. This would I guess induce less time on the pedal. The only time you would be on the pedal would be to accelerate back up. I know on some good flat surfaces you can glide for quite a while. If at high enough speeds. I guess sort of in spurts I wonder if this would be effective anybody with scanguage to find out. It be sorta like what you do on hills. Except doing it all the time.

it's caleld pulse and glide. well known and used by hypermilers.


Checdk ou the general forum and there are 2 threads there that you should check out. have all kindfs of tips and discuss mods.

Yep, it's called "pulse and glide" (or "burn and glide" by some, if you hit the gas really hard). It's a technique that goes way back -- I remember a Popular Mechanics or similar from my childhood with an article about a test vehicle that got something like 1,000 miles per gallon by using a tiny engine and doing pulse and glide at very low speeds.

Search the forums for "pulse and glide", "burn and glide", and/or "P&G" and you'll find lots of useful information on the technique.

Pat yourself on the back for thinking of it independently. :thumbup::)

P.S. Haha, good going Mike, you hit your "Save" button three minutes faster than I did! :D

well so far what I have read on this forum talks about doing such effect on hills and other surface slope terrain. Not on flats or maybe I have overread it if I'm wrong.

we do it on flats and anywere we can get an effective glide. we also turn our engines off to get that extra little edge.

Hilly terrain is definitely where the current P&G discussion is centered. I know that P&G has been my biggest contributor to FE :

I think that once you have mastered P&G for your route, aerodynamic mods become more important to extend the gliiiiiiiiiiiiiiiiiiiiiiiiiiiide.

Though not those of us with typical automatic transmissions, as that tends to fry them. :D

As CarloSW2 said, "current." Search (either here specifically, or Google in general) is your friend. ;)

Rick,
Maybe only in the 2000 years and up range.
My 89 celeb, 93 prizm, 96 monte, 97 cutlass all do very very well with EOC'ing
I drove a 1999 dakota RT and a 2001 olds intrigue that didn't seem to like EOC very much, so for the newer stuff maybe its bad...

Yeah, yesterday I turned off the engine when coasting, and, well, it didn't turn back on (unless its in park. I missed an important green light for that. If you have an auto, leave it on. I also remember reading that it takes a lot of juice to start the car, so I don't even know if it is economical to turn it off at all.

I use it a lot on the highway, At higher speeds it shifts seemlesly from D to N and N to D. At slower speeds a small clunk is felt. Good luck with your burn & glide.
