Neutral Vs Glide

darkecho · 08-12-2006, 06:25 PM

Gliding = coasting with no arrows, no drag, no ICE/EM....

Neutral seems to have those same attributes, HOWEVER! I heard that regen braking doesnt work in N...

is that the only difference? cause for those of us who get frusterated with trying to find that sweet spot, perhaps we could throw it into N and when we need to brake, we can put it back into D and start braking...

why doesnt putting it into neutral at high speeds work? does the ICE still come on regardless of Drive or Neutral above 42mph???

Yes, you're right...there is no regen braking in N, and I believe the ICE still has to turn above 42 mph.
Supposedly there could be a (lubrication?) issue if you keep it in N too long (minutes?), so it's probably good to put it in D occasionally on really long downhills.

I use N all the time without problems, although some people say it's dangerous (and illegal).
I think the risk of looking at the screen to achieve glide is higher than the risk of being in N and needing unanticipated acceleration. However, anytime you might need VSC (like snow, rain, high speed corners), I wouldn't use N.

[N] is a cheat for gliding.
Before I could get the gliding consistantly, I would drop into [N] to simulate the benefits. However, all the things Karkus said are true. If you are on a newly paved straight-away at noon on a sunny day with no other traffic, have at it. As you change those variables use at your own risk.

Because the ICE really does continue to run, it is not technically the same as gliding.

So N is identical to gliding except the engine keeps turning (albeit at a low rate) so because of the extra drag of the engine, you arent going to be able to acheive the same mileage as gliding....?

also, below 42 mph if you use neutral while the ice is running, it seems like it wants to stay running a lot longer than if you were to glide. i also believe if the ice is not running below 42 mph, and you then put it in neutral and go above 42 mph, the ice won't spin up (someone would have to verify this with can-view).
as for lubrication, i believe that's provided by the ice, and neutral or glide would not make a difference.

so as long as you get the ice to shut off first below 42 mph, there should be no difference in the effect (except safety).

I probably use N more than anyone here. We have had long discussions about it in the past. I regularly get high 50s for mileage and my highest is 818 miles at 65.1 MPG through the regular use of N. I use it for about 15% of my total miles.

As for warnings by others, I have decided to be the test case for the practice and can report that there has been no noticable problems for 57,000 miles so far and my wife has racked up 30,000 miles. I've been responsible for adding 11 prius to the roads besides mine and many of those drivers practice the same technique. I can't really say anything about the many grand prius that are on the road as a result of those 11.

I use N all the time since the discussion around long upgrades somewhere on here. Of course I use N for the other side of those long upgrades!

I think I am a little slow to understand the P&G technique as well as the use of Neutral. I think the only time I am in neutral is when I first power up. Could you please direct me to the earlier discussions about the use of Neutral. I did a search but couldn't come up with anything! Thanks!

Here's a search link. The tread starts a little wierd because the original thread was before the switch over to the new forum so some of the original posts were lost.

Hmm can someone with CANview tell us the differences between N and Gliding? Particularly if the engine stays on, and how long...

if N is sort of a more garunteed/less hassle version of glide, that might be the best route to go.. then just switch out of it if you want to brake.

it would most definately be safer because instead of watching the MFD you have your eyes on the road..
