I added it at the following link with the same video unavailable due to location: https://docs.google.com/open?id=0B6E...0RSOGtyaUtGVnM
Quality's not there at all in the video though you may get a sense of the speed;... you can hear the toots of other motorists at the end when he's running out of battery.
"Honda Insight 3+ km on IMA battery. Speeds vary from 40 to 72 km/hr. Road mostly mildly downslope with 2 long flat parts."

Thanks, yes, he is abusing the "EV" mode of the i2. Guessing its in metric, saw the dash read 54 one time and 78 another.

Forget about it, the app doesnt tell you half the time either. I just read what looks interesting and move on.

I need to get my hands on a gen 1 and just see if there is some undocumented ev mode.

There is with MIMA/IMAC&C

I just drove all around the parking lot at my apartment complex with 2 notches of IMA dialed in in 2nd gear and the injector pulse width read 0 .

AFAIK these are the options I've seen in my I1... none are efficient due to the attached ICE air pumping ... and limited 10kw IMA... and limited IMA battery kwh ... etc.

Option #1>
With MIMA if you force enough Assist and high enough ICE RPMs to get into fuel cut mode you are in a pure EV Mode ... will work in any gear or speed ... as long as you have enough Assist induced load and high enough RPMs to get to fuel cut ... I've done this a few times years ago as an experiment in all 5 gears.

Option #2>
Same as Option #1 , except using FAS to force a fuel cut at lower RPMs and or Assist levels... I did this a a few years ago during the same experimenting , and was able to go 3.7km from a dead stop up a slight incline.

Option #3>
If you are already getting some assist when you run out of gas ... you can keep going on IMA Assist until you also run out of IMA battery... I did this during the same experiments where I used FAS to simulate running out of gas , and just flooring the gas pedal in higher gear to get the IMA assist , without using MIMA ... but the MIMA options in #1 and #2 above do given more control over the amount of Assist being used.

I do not know if this behavior is the same on all versions ... but it worked consistently with my 2000 I1 a few years ago when I did the experimenting with it.

I could be wrong ... but I thought the I2 made use of the closed pistons ... turning the pistons into air springs ... and thus had a more efficient EV mode ability due to not running the ICE as a air pump.

Doesn't the Insight have the same valve-shutting v-tec mode where the cylinders act as air springs in fuel cut mode? At least in the hch1, this means there's not all the pumping losses, just a lot of friction losses in the turning engine.

No it doesnt. The HCH1 is much more effcient at regen than the I1 as a result of this. Also Asfaik The HCH1 only does the air springs shut off when decelrating/fuel cut on three of the four cyclinders.

Oh weird, I thought I was just nuts remembering that one of the cylinders had different valve clearances than the other three. Guess that explains that.
