What does SoC stand for?
I'm really lost with some of these Abbrev. Would not hurt my feelings at all to see a list in (Plain-English) on this thread as to what the Abbrev. is and the (Spelled-Out-Term-In-Full-English).
This is a "Really-Great" Thread CGameProgrammer, Excel ; you all are covering alot of territory that alot of us with the 06 HCHs are interested in.
Thanks Guys;

Don't feel bad, I had no idea what these acronyms were either, until I found the GreenHybrid glossary (see the link at the top of the page)

Now that I'm clear on what you mean by HS-P&G, I'm a bit confused. Since you are not using assist on the pulse, and not using regen on the glide, it seems like you are essentially 'turning off' all of the hybrid features of the car. I mean, you could use this technique to get great mileage on any car, the hybrid just makes it easier to turn off fuel in the glide. In my 99 Accord MT, I can do it by popping into neutral and turning off the key. How does the fact that it's a hybrid help the mileage?

Once the SoC gets down below a certain level, it won't let me cancel out the regen on a glide. Any throttle pressure starts the ICE back up so it can keep the regen going. Once the SoC gets back up, I can go back into fuel-less glide.

A "If-You-Will" plain Gas Vehicle, regardless of it being a car, suv, truck or whatever (Does-Not) have the (Usually) small highly Efficient Gas Engine that the (Hybrids-Have).
So I may be doing a Poor job of explaining this here, your right there is (NO-Difference) at all in doing the same things you are talking about on the Hybrids versus (NON-Hybrids) other than the Smaller ICE and the CVT plus in some cases the Hvbrids are more Aerodynatic as well.
The other thing that comes to my mind, is that with the Hybrids they are (Really) designed for the "Average-Person" to be driven and under just normal every day driving either in stop and go or hwy. They give really alot better (FE) than the same vehicle without the New Technology that has been developed for and in use on (As-An-Example) the 2006 HCH ll. The Hybrids are doing it for the Driver in everyday driving without the Driver really participating to any large degree (IMO).
The Hypermilers are (IMO) just taking the Hybrids to the "Next-Level" in FE. The Hypermilers do the same thing with FE in (NON-Hybrids) but the results compared to the Hybrids are not as drastic, simply because of the difference in the two technologies. (HYBRIDS/NON-HYBRIDS)

Re: EV (electric-only) mode finally spotted in 06 HCH!
Terry is mostly correct. In truth, when you accelerate without assist, you are accelerating for a longer period of time than you would if you let the electric motors help you, which does use more gas. But we have seen that the gas savings in using assist is usually dwarfed by the gas wasted compensating for the car's tendency to employ regeneration. It would be one thing if the battery were recharged only when braking... that would be best of all.
However, it would not be good for people like me who actually like to reach our cruising speed sometime before we reach our destination. The electrical assist compensates for the engine's weakness, and the reason the engine is weak in the first place is because it usually allows for more efficient cruising. (This depends on exactly how weak the engine is and now aerodynamic the car is.)

That's true, I guess another way of looking at it is that the IMA system is not there to improve mileage, it's there to make up for the anemic ICE so that the car performs like most people expect. The real fuel savings comes from
A) A smaller, very FE ICE
B) shutting of the ICE whenever possible
You might get the same FE if you disabled IMA, but the car would be much less responsive.

I don't know how the RAV4 EV manages active braking, i.e. does it use regen to supplement the frictional brakes or not.

Re: EV (electric-only) mode finally spotted in 06 HCH!
why is regen bad? i have tons of hills that are greeted with a stop light. plus if your going down a hill too fast at least regen can prevent you from going over the speed limit. When you guys say regen is bad you mean hitting the brakes are bad? So its better for the car to regenerate by letting go of accel for maximum FE?
this hypermiler **** is too complicated! why can't i just feather the pedal and get high mileage? and make most of your stopping distance to absorb all the energy from go to standstill isn't that enough?
