Coasting in neutral with a CVT

Re: Coasting in neutral with a CVT
There are only a few times in my commute where I use EV Assist though. Based on other posts here, it's better to dip slightly into the gas than let your SOC drop below 4 bars because of forced regen hurting your milage. I generally only use EV Assist after long hills when I have electricity to spare.

You must have posted while I was typing my post
What happened to your SOC over that stretch? I have very few segments on my commute where I can use EV Assist for more than a 1000 feet or so because of hills. I generally don't bother with it, but maybe I should do more playing around.

Re: Coasting in neutral with a CVT
If I do end up with SoC down to 4 bars and forced regen happens, I still watch my iFE and adjust my foot on the pedal to keep the mpg at 50 or above as much as I can while not worrying about my speed so I don't take any hard hits on the mpg.
I'm not sure how big the hills are in your area. Here in sacramento, the hills aren't large hills, but the road sure isn't flat. The elevation change of most of the not-so-flat roads are only about 20-40 feet difference, but it can get annoying because it's constant rolling hills. I can keep EV Assist on the up and downslope of these hills with no problem (speed fluctuates going up and down). I will take advantage of the downslopes and drop out of EV Assist to gain some speed quickly while keeping iFE above 50, then drop back into EV Assist.

There is no harm other than I was a bit aggravated when it very much seemed you were trying to take one word from my post out of context to try and give it a new meaning.
A few points here:
Concerning the "professional", I doubt he has had any experience with failed transmissions from such a new car--especially those as a result of people shifting from neutral to drive while moving. Also, I called the service department from one of, if not, the largest dealer of Toyotas in Colorado. I asked about getting an engine block heater installed in my new Toyota Highlander Hybrid. The "professional" head of service told me that Toyota does not make any engine block heaters for hybrids because they all leak. Anyway, I called another Toyota dealership and ordered my genuine Toyota engine block heater.
Do you seriously believe we are doing this over a few tenths of mpgs per gallon? Today, I did this technique at speeds low enough so that the transition between Neutral and Drive was very smooth. My two segments were 72.1 mpg over 7.1 miles and 112.9 mpg over 5.4 miles. This averages to 85.4 mpg over 12.5 miles. I can assure you that this technique resulted in an improvement of more than "a few tenths".
Well, I shouldn't have said that. I was just a bit annoyed at your post and quickly typed a response.

Re: Coasting in neutral with a CVT
Noflash: Find yourself a road that is level and not too busy. Go out and practice. Get up to 45mph and release the throttle and watch the mpg bar hit 100mpg. Now you will notice you have two or three bars of regen.Push on the throttle untill one bar of assist, you are in EV mode, as long as the mpg shows 100mpg. You can feather the trottle up to 4 bars of assist, after that the ICE will kick on. If you practice this it becomes auto to you. Have fun, H

Re: Coasting in neutral with a CVT
In the HCHII, do you guys really think using EV glide is beneficial for fuel economy? It provides such little power and really drains the battery. For me, there are rare occasions where I think it is OK to use. Mainly, when I am coming down mountains with a full charge and don't want the ICE to kick on in areas where the road levels out a bit.

John, how in earth do you get the kind of numbers you do without using this mode? That and coasting are the only ways I can do it , thus fare. I have only 6000 kil. on my car and have alot of technic to learn. I can manage #'s in the 70, 80 range, but only for short milage. 10 miles max.. H

One thing I have done is gradually up my tire pressures to 44 psi. Early on, I used the EV glide (with assist) a lot, but it seemed I was draining the battery and paying for it later with forced charging.
