Interestingly I find regen braking one of my favorite things

Bolt has even MORE aggressive regen than the Leaf

We need to be careful about terminology. To me "regen" means "recapturing kinetic energy / momentum into charge / SOC, braking while doing so".

My understanding is that the Bolt "slowing to zero mph while not applying friction brakes" includes using battery energy to do so. If correct, I wouldn't label this regen.

As for the Leaf, using the friction brakes doesn't sound like regen to me:

E-Pedal mode on the Leaf boosts the regenerative braking by a massive amount, meaning that when you lift off the gas the car slows down very aggressively. It'll even bring itself to a complete stop and hold itself there using the physical brakes, even on a hill, until you hit the gas again.

You are mistaken.

You are mistaken.

Looks like I misremembered (or the article I read a bit back was wrong). Mea culpa.
It seems like it was friction brakes, not battery consumption:

Chevy has tuned the complex powertrain-control software to blend increasing amounts of friction braking into the waning regeneration as the car slows at a stoplight, for example.

What IS 'one-pedal driving' in an electric car?
Again, for the same reason as the Leaf, calling it "regen" is as incomplete/deceptive/confusing as the FUD around "EV" labelling of hybrids, IMO.

One pedal driving, sure. "Regen" no.

The Bolt does not have "blended" brakes. If it did...it would have Adaptive Cruise Control. Your link is to a really old article.

So John Voelcker GCR article is incorrect? Link?

Search for "chevy bolt blended brake" on google or bing, and the internet seems to support John's assertion. (That doesn't make it correct, but worth observing.)

I was a downshifter, which matches up very closely with the regen experience. No brakes until the very end. And now I don't even have to shift.

This helps me not miss my Manual Mini Cooper

Bolt EV has blended brakes via Bosch. [Archive] - GM-Volt: Chevy Volt Forum

UPDATED: Yes it does have blended braking, just a different tech and supplier, see how and why here Bolt EV has blended brakes via Bosch.

Bolt EV has blended brakes via Bosch.

The answer, according to Ligouri, is that the Bolt EV uses a new and better-feeling brake pedal system that continues to include both enhanced regenerative and friction braking.

Also this makes no sense to me:

Adaptive cruise control - no, you would need the blended brakes to do that

He seems to be implying that Tesla is using blended brakes and that no non-EV can do adaptive cruise control. Both are nonsensical.

Makes it hard for me to buy into anything the guy says.

That really doesn't tell me much. I don't see words such as "only" in the important places.

Would also be interesting to hear from Bolt owners how the One Pedal Driving experience is when the Bolt is fully charged. If it remains unchanged / as effective, then where is the "regen" going while the battery is full?

The part that you're apparently missing is the first 2 "updated" lines are newer than the rest of the post, and point to the other link where there is newer information based on a follow-up with Ligouri -- which in the same post of mine that you're quoting.

Regen is very low or zero when fully charged. Thats why most use hilltop reserve which charges to 89% so we get full regen.

Believe what you want...friction brakes in the Bolt are only applied using the brake pedal.

 

[Nocturnal]

I love it. To me it really feels like driving a manual and the feel of engine braking.

 

[Enginerd]

I'm also loving the regen. Interesting characteristic though, if you point the car slightly uphill with creep off and foot not on brake. Unlike a traditional automatic, it just rolls backward with no apparent resistance... more like a "neutral". Now I double-check the hill hold (H) is active before I let go of the brake, to prevent a subsequently embarrassing minor accident.

Yep. Good article regarding the Leaf's E-Pedal...yeah...they say "gas" a bunch...but one gets the point about TRUE one pedal driving: 2018 Nissan Leaf long-term update: One pedal (near) perfection

and....the Bolt has even MORE aggressive regen than the Leaf: Anxiously waiting an AWD review / videos

From Motor Trend:

...

Well, from this graphic the Model 3 regen sucks. What, do I have to buy a D3P+ to get track mode just to get decent regeneration? I was hoping the the Model 3's regen could be configured to be at least as strong as my Volt driving in low (which I do 99% of the time).

 

[Glamisduner]

Bolt has excellent regen and I especially liked the paddle that will bring you to a full stop without using the brakes, but Tesla's isn't terrible.

I sold my volt last week and I must say, driving my ICE to work while I wait for the delivery feels very primitive and wasteful every time I stop.
