Note to dialup users: Video is a 20MB mpg file and will probably take 5-10 minutes to download. Recommend download to hard drive.

It took a little work to figure out how to pulse and glide behind my home in the alley and down the street to the first stoplight 0.4 miles away, but here is a video and still pictures illustrating how it was done.

Typically I do this at 6am when traffic is very light. Normal driving would get a result of 50 mpg in my Insight - P&G as illustrated yields 100-200mpg (139.5mpg in this instance). While I hand anchored the camera against the sun visor, it will still be a bit shaky - sorry.

To see Video, go to this page (http://www.cleanmpg.com/photos/showphoto.php/photo/2888/cat/500/ppuser/9), then click to view or download video

A video description:

Already off the ramp in behind my house in the alley with a half-second pulse and glide to exit the garage and climb three feet (one meter up the alley)
(Begin Video) Start the car
Get to 25mph in 20 yards. (Fast - I usually cut off at 20mph. Yes, I brake for children and jackrabbits)
Cut ignition (dash goes dark) No more gas on the rest of video!
Glide 100 yards or so down the alley, turn ignition back on. Ignition has to be off 2-3 seconds or engine will "diesel" back on and defeat the gas savings of pulse and glide.
Sharp left turn (wish the Ford F350 was at the end of the alley this time for a Doom II monster effect :D )
Go 20 yards to the end of alley into resdential street.
Sharp right turn to residential road. Don't worry - the silver PT Cruiser is safe!
15 yards on residential road
Sharp right turn to get on major road. I do look for oncoming traffic.
Glide 0.2 miles downhill to traffic light. (End Video - see pictures below) Got 139.5mpg instead of the typical 50mpg at this point. I've gotten 100 to 200mpg.Pictures of the Rest of the Glide After the Video

MPG reading in alley: 20mpg

Past the alley on the major road at 0.2 miles - 66mpg

Crested a hill starting to accelerate to the stoplight ahead - 92mpg

Almost there

Finally at the stoplight 0.4 miles from home - 139.5mpg.

What if the light turns green? It's a bonus - turn the engine on, get up to 30-35mph, coast 0.5+ miles to the next stoplight.

Maybe this makes an excellent case for EV mode. :D

That is really cool little video. I've been dying to see how other people have been pulsing and gliding. I like the GPS also on the dash.

Chuck, enjoyed the video and explanation.

You've inspired me to get my own photo/video section going. I've been wanting to put up a video of my favorite part of my commute (2 miles+ sans gas). I just need to finish up the soundtrack and get Matt Damon to play the role of me.

His next role (http://www.tvsquad.com/2006/06/21/matt-damon-might-play-captain-kirk/) might be the polar opposite of hypermiling. :D


In the video, I went a little faster than normal. Along with a lack of a solid tripod and the sharp turns, makes it edgier than it probably is.

This is sharper, and a little shorter than the original video

Thanks for posting the vid. There are a couple of places on the commute that will work on. I wish my scangauge stayed alive longer with the engine off so it would be easier to tell the effect.

The camera I did the original video is on it's last legs - got a new one.
