I really wish that they would reprogram or offer a software update to have the Volt come to a full stop using regen rather than creep in low. The creep although doing exactly what it is designed to do —- mimic a gas automatic transmission— is irritating in this car and my leg gets tired of the brake pedal, which given the strong regen and the regen paddle I really only use now otherwise for sudden stops. Since they apparently implemented this in the Bolt in low, I assume there is no hardware related reason they couldn’t have that code deployed in the Volt? Really wish they did...

I must say it is something I got used to very quickly in the Bolt. Now when I drive the Volt, Low feels like Drive, hard to tell them apart compared to using Low and/or the regen paddle in the Bolt.

Right I’m sure that software coding would take care of this in the Volt if they would care to do it

Holding the regen paddle won't cancel creep; you get down to about 1-2 MPH and then it "lets go" of regen and starts creeping again, up to about 3 MPH in L or 5 MPH in D.

I would love for them to program an option to disable creep and enable one-pedal driving in L. It's a matter of getting their firmware developers to write it; they're probably focusing on other things sadly.

My guess is since this is already existing in the Bolt it would not take much for them to port the programming over to the Volt!

Regenerative braking uses the car’s kinetic energy to crank the generator, which can recharge the battery while braking the car. It can’t hold the car at a complete stop because there’s no regen when the car’s not moving. Engineering the vehicle to "creep" or not to "creep" once it’s stopped is a separate issue.

...and we await with bated breath the unveiling of Gen 3 with new goodies (maybe full stop with the paddle or Low).

The Bolt consumes a small amount of energy to slow down the car and hold it at a stop once regen becomes ineffective when using "single-pedal driving". It'll use a microscopic amount of the energy you recovered from the actual regen to do this, so it's not entirely wasteful, but I'm sure it does shorten the range a tiny bit compared to using the brake pedal at low speeds.

I always thought of the Volt line as a gateway EV and thought the lack of full stop on REGEN (paddle or L) was on purpose so users wouldn't get caught off guard with lack of creep (assuming most drivers came from an automatic ICE).

I'm also not a huge fan of the full-stop via paddle or L since you're not actually applying the brakes. I don't have a good rationale, but having my brake applied at a full stop always felt safer. On the Bolt I actually miss the creep of the Volt when using the paddle. It's a good reminder when I come to a full stop that others behind may not know I'm stopped (no brake lights). True, it's the people behind me that are responsible for judging distance to me, but the brake lights help them out immensely.

I agree that the brake lights are strange, but when I've seen i3s driving around, the brake lights only turn off once they're almost completely stopped. At such a low speed, the person in the rear would have to be very distracted to rear-end the car and the brake lights may or may not make a difference

I noticed in the model 3 video an option to switch creep on/off & thought that was something that seems simple and that they should offer in the volt. I really like driving in L, but wish I had that as an option.

Seems to me that given the Bolt uses essentially the same control hardware and this is already written into the Bolt code for L mode, GM could easily update the Volt software to provide this option.

It would be nice if GM would have the brake lights come on with the use of the regen paddle. Otherwise, I'm fine with the way it functions and don't mind lifting my foot to the brake if needed. Just my 2 cents.

While a full stop may be practical in a BEV because there is just one motor, the Volt has a separate traction and generator motor. The generator is only 55kW. Volt has to constantly switch between these motors as the vehicle decelerates/accelerates. So, the regen system is significantly different from Bolt, and not a simple software update.

I use L a lot of the time to take advantage of the regen, but I do get nervous about the lack of a brake light. I have had cars run up on me when I slow, and finally went back to D during a long stop & go session on the expressway after having a couple of guys behind were not paying attention. Maybe I'm overcautious, but I had a great Volvo totaled out by some jerk behind me who was playing with his radio and didn't notice that traffic had stopped.

Were your brake lights on when you lost the Volvo? Maybe it's not that helpful when stopped... (Heck, people rear-end FIRE TRUCKS with the whole array of lights going. It seems like this is a hole with no bottom...)

Gen II Volts not only pay attention to the pedal but also the slowing rate, and turn on the brake lights when the rules call for it. I can't remember what it is in meters per sec^2, but it works out to about 0.1g. https://www.youtube.com/watch?v=_F4iyghT-qA
