Neutral Vs Glide

[tomdeimos]

In neutral you can not charge the battery, and it will discharge some due to your normal electrical loads.

In glide without arrows you are still powering those loads from the engine and charging or discharging the battery a bit. I can glide with no arrows easily, but with can view on current I can not hold it exactly at 0 or any other place for long.

Since the electical load varies with AC fan speed etc, it is hard to know what current to try to hold. 0 amps means you aren't really coasting because you are generating power for the electrical loads.

The no arrows just means power to the wheels from the battery is very low.
But it won't be as low as neutral.

True coasting requires holding something like -3 to - 6 amperes typically, so you are draining the battery to power the fans etc, and not adding drag. But like I say this varies when a fan speed changes or another pump turns on or off.

I believe that in most states it is illegal to put a car in [N] to glide. Better check local laws could affect insurance in case of an accident.

And I believe you're right and thanks for making that clear.
It's one thing to look for methods to help improve mileage but when you've violated traffic laws you risk more than just low mileage. As I said above, I'm guilty of slipping into [N] and am not trying to be hypocritical. But Wildkow's right that we need to keep the law in perspective when we try things.

I definatly am not going to do something illegal just to improve mileage. I am well enough if I can simply understand Glide. When I speed up and then take my foot off the gas peddle I have blue arrows from the wheels to the battery. Apparently that is not Gliding? I thought blue arrows from the wheels to the battery were GOOD because that means you are charging your battery, no?

Why would I want NO arrows to the battery?

p.s. I am not a scientist, I am just a 32 year old female Prius driver that at one time knew how to change her own oil and unsuccessfully rebuild the carborator for my first car, a 1974 Toyota ?? (pea green and super sporty. All that beside the point, please explain in as preschool fashion as possible without mentioning amps or voltage(you can but I won'y get it)

THANK YOU DEARLY!!!

If you are seeing blue arrows, I think most people on this board would call that "coasting" not "gliding". Gliding is moving with no arrows, as I understand it.

Blue arrows are good in that you are getting energy back, but the energy has to come from somewhere. In this case, the energy is coming from your car's momentum. Basically, blue arrows means the system is using the regeneration to charge the battery. When it is doing that, it is slowing your car down, even if you aren't braking. It's like letting off the gas in a regular automatic; the car will start slowing down because of the engine compression.

Gliding, then, is holding the accelerator such that you don't have any arrows. This means the car is still moving forward, but the regenerative system isn't eating your speed to charge the battery. You can drift along further than you would with the blue arrows showing.

Did I make any sense?

Coasting - No brake, no gas with blue arrows from wheels to battery - battery regeneration via energy from cars momemtum (some Drag)

Gliding - Gas pedal with NO arrows of any kind/color (no Drag)

Neutral - No brake, no gas, Neutral transmission, No arrows (No Drag)----ILLEGAL and DANGEROUS!!

If what I said above is correct you made tons of sense! Thank you!!!

How's the OK heat, I know we are frying down here in Texas and AC HURTS the mpg, hopefully the winter will be easier on it.

You've got it! I'm glad that helped.

Ugh. I hate being hot, so I'm really ready for winter. It's pretty humid here lately, but I don't think it's as bad as the heat you've been having in Dallas. I need to move further north. We actually had a high in the 80s yesterday, though. It was a nice break.

on top of all that, doesnt neutral keep the enging in an idling condition as well? making it less efficient as gliding (where the motor can shutoff)?

Really. . . Just the kind of woman I've been looking for all last hour.

In a simple way:
When your engine is running, you're consuming gas.
When you are Stealthing, you are consuming battery.
When you are Gliding, you are consuming neither.

And yes, as mentioned, [N] does not turn the engine off so you are consuming gas.
The overall goal is to consume the least amount of gasoline required to get from point A to point B (or my house if you're a 32 year-old female Prius owner). Stealthing is good because you're not consuming gas; Gliding is better. Gliding is always better.

If the car is warmed up, the engine will not be on when in N.
