What's the fastest you've gone while in auto-stop?
 

A couple of weeks ago, I slowed down at a stop sign and my engine auto-stopped. I usually do not AS at this intersection, because my car was not warm enough. Anyways, this day it was already warm, and I rolled through the stop at about 5mph. I turned right, going downhill. I got up to 20mph without taking my foot off the break, staying in AS mode. (I had to slow down at the next stop) I know this is no different than being in EV-glide gas wise (EV glide is probably better, because you can regen if slowing down), but I was just curious if anyone else has done this, and what speed they have gotten up to. I have some pretty steep hills in my neighborhood, so I may do some experimenting just for fun.

Downhill in city driving during rush hour just after a traffic light, I got up to 35 before I had to turn :)

Wow, Yangsta!
I've gone up to about 20 on multiple occasions, but rarely any more than 20.

It was pretty much the perfect storm of situations -- I haven't exceeded 15 or 20 with the exception of that one time :)

I got up to 25 once - it was a traffic situation on a hill I drive everyday. There was some construction because there is almost never traffic here. When I finally let off on the brake - the transition was quite rough. Like you would expect if you were trying to start a MT car by rolling down the hill and poping the clutch.

Re: What's the fastest you've gone while in auto-stop?
 

Yeah. After letting off at about 15mph, I decided to slow to a stop before accelerating. Even though it isn't fuel efficient, I really don't think that clunk can be good.

Re: What's the fastest you've gone while in auto-stop?
 

Save your transmission guys! Don't do it!;)

Re: What's the fastest you've gone while in auto-stop?
 

I felt that clunk once before. I didn't like the sound or feel of it. Haven't done it since.

Re: What's the fastest you've gone while in auto-stop?
 

Or slow back down to under 5mph before letting the gas engine kick back in. That's what I do. You have still overcome inertia (you're rolling), but you're not killing the tranny.

I got it up to 29 today. I slowed to a stop and then let the engine turn on. No clunks :D

Re: What's the fastest you've gone while in auto-stop?
 

I've gotten if up to 25mph. If you keep your car in neutral, when you let off the brake you wont get that clunk. Then wait a second and swich to Drive

It's not a good clunk- you are playing with fire by doing this as you could damage the CVT (since it is expecting a low rotation and it gets a high rotation). It almost felt like it could snap the CVT cable..
I sent in a comment about this when I got my survey from Honda- I think they should automatically start the engine if the speed goes past a certain threshold while in AS.

Re: What's the fastest you've gone while in auto-stop?
 

I imagine this wouldn't be an issue with a MT as you can just keep the clutch in and put it in the appropriate gear for the speed you are coasting at and let the clutch out.

Re: What's the fastest you've gone while in auto-stop?
 

I usually don't go too fast or far traveling and keep it in AS. The reason is I have to use the brake pedal. Surely it seems that I'm not yet applying the hydraulic brake, but can I be sure? I don't want to take the chance of dragging my brakes for that long.

Forced AS is another thing with me, I have no problem with it in certain situations. For example I have a mile and half of slight incline when I leave the house in the morning.
All cars are a comparative fuel PIG when warming up, and I see it for that time.

But on the way home I can force AS and coast around 30-35MPH for that last segment and drive the FCD up over 60, if it isn't there already. ;)

I've gotten up in the mid-teens and it just happened to be luck at the time. It was in a "stop n go" morning rush hour and on a downhill. I try to actually get my car to AS on that road at that point when I take that route to work. It always comes back to a full stop or under 10 MPH before I end up taking my foot of the brake. I would have to agree with the rest, that getting the car moving to a higher speed and then having the ICE kick back in can't be good. I would imagine that any action that creates a noise different from the usual hybrid noise isn't good.

On another note, anyone see the You Tube video of the compressed air car??

Re: What's the fastest you've gone while in auto-stop?
 

That's cool, but wouldn't it be more efficient to just power your car with electricity, rather than converting electricity into compressed air? At least its a step in the right direction (away from petroleum)

Re: What's the fastest you've gone while in auto-stop?
 

That's a good question. I would imagine that powering with electric would be better, but you can only get so far with that before needing a re-charge. Plus, compressed air in the long run may be better than battery power, but what do I know! I think it's a cool idea, but can only imagine the noise a compressor for that would create as well. How about a combo electric & compressed air car? I wonder if they would find a way to use all the friction, etc to help charge the battery & power the compressor?

Of course, according to the jetsons, we'd be flying around town by this time!

I got stuck in a traffic jam on Wednesday and sat on Auto-Stop with the A/C, windshield wipers, headlights and stereo on for almost 20 minutes. I went from one bar short of full charge to 2 bars short of empty in that time. I wanted to see at what point would the engine kick back in to recharge, but then traffic started moving again.
