CVT coasting

Just curious if it is safe or even possible to coast in neutral with a CVT like with a conventional automatic? I have tried putting my Civic Hybrid in neutral and it did drop some RPMs, but I have heard that it could damage a CVT so I am hesitant to do it regularly. Any input?

Thanks

The Honda CVTs are notorious for reliability problems. I have coasted in neutral in my first gen Insight CVT and in my Altima CVT without any problems. As long asyou do not have re-engagement rev match issues I think you would be OK, but take any advice with a grain of salt.

The problem is when you coast with the engine off, there is no lubrication. As long as the engine is going, you got fluid moving. I do it off and on. Mainy when I had my phev kit running as I had no need to regen. Otherwise regen came in handy for hte next stop.

I guess I'll just skip this with the hybrid then. Still do it often with my old Toyota though.

I'm curious now, what happens when you let completely off the throttle? Does a CVT run the engine RPM up enough to put it in DFCO?

Do CVTs tend to glide better or worse than an automatic?

You can coast in D with the Toyota hybrids. You have a point where neither the EV nor the ICE is pulling, and that spot acts as neutral, and you can coast very far when the tenique is learned.
Coasting too fast in N can ruin the system.

The insight does the fuel cut thing. It applies a light braking effort and dips into regen when you start to lift your foot off the throttle. It holds the engine above idle, 1500 rpms most of the time with light load.

Light pressure on the throttle allows it to coast. Now if you are in sport mode it engine brakes on top of this regen braking effort and it runs the engine to 3 thousand rpms. This isnt done in econ or regular drive mode.

The middle and top models with nav have steering wheel paddles to select a of 7 ratios for a fake gear.

I couldnt say about coasting with a cvt vs a non cvt. Depends on the fluid in the tranny I guess?

Exclamation

I'd really like to know whether coasting in neutral with engine on in a CVT is safe too, especially in a OBD-I era car, and whether it should only be utilised when you know you have to come to a stop such that the car can put back into 'drive' when stationary.

I plan to create a thread solely for my 1996 K11 Micra 1.3l CVT and the issues I've had getting within even 25% of the claimed figures but the biggest problem seems to be that my car has almost zero coasting ability; it feels like it drops a figurative anchor whenever I let off the gas...

How many cars had CVT during OBD-I?

Are there any noises when you release the accelerator? It sounds like a mechanical problem, perhaps one or more dragging brakes. Please take your cold car for a quick drive around the block, accelerate to 30 MPH (45-50 KPH), coast to a stop, and then carefully see if one brake is warmer than the others.
