Low Regen mode coming back?

[HTWorld]

It’s not a big deal since I’ve been able to adjust regen using S3XY buttons to a much greater degree

What are those? How do you adjust regen?

What are those? How do you adjust regen?

They are programmable buttons that sends commands through the CANBUS via a transmitter. One of the functions available is to adjust the regen level from 0%~100% in 25% increments (among several regen adjustments available). I actually prefer full regen all the time, but it has been useful to replicate ICE car operations for my daughter using my car to practice driving on her permit.

Just google S3XY buttons or search in these forums for more information.

Thanks, they look awesome and are likely to solve the regen problem! Ordered.

What’s the current status on this? I test drove a new long range S and there was no option for low regen, or creep and roll modes. My 2019 Model 3 has all the above. Is the new highland 3 having these modes or not?

 

[E90alex]

It ended up being in China only I believe.

Is creep and roll modes dead too though?

No, still active

Weird, the 2023 S LR I drove didn’t have those options. Maybe it’s an S thing? Or just a demo mode thing?

Nope, those modes don't exist on any newer Teslas. I don't know which years, if at all, they existed on.

Creep and roll?

Creep and roll?

Yup, no adjustments for those on my Feb 2022 MSLR. I don't know about those on any other Tesla ... somebody will chime in if they know.

2023 Y’s and 3’s have creep and roll. I’m pretty sure previous years do as well.

 

[arghx7]

Ok so no creep or roll modes is an S and maybe X thing then. Weird.

I don’t get the benefit in removing them as an option. I understand removing low regen because it has some benefit on EPA range rating, but taking out creep and roll is pointless.

2024 model 3 has no creep nor roll option, full regen only (recently delivered in Holland)

Getting rid of roll as an option makes no sense. Since kinetic energy goes as v^2 the extra energy you recover with regen down to 0 mph vs 5 mph is basically a rounding error. I personally prefer roll to one-pedal, would hate to give it up.

 

[E90alex]

Maybe it’s a technical problem they don’t want to deal with solving.

The refresh S/X use dual permanent magnet motors. Permanent magnet motors don’t like to freewheel so in order to creep or roll some energy needs to be sent through the motors. Maybe the difference in gearing etc between front and rear makes it too difficult to sync and roll/creep smoothly?

Wouldn't that apply to just applying very low throttle to maintain a set speed similar to what creep and roll would do anyway? And I believe the cars do still let you put them in "neutral" while driving, which wouldn't be so different from how roll worked. Plaid also has same gear ratio front and rear, though I could see them not wanting to differentiate plaid and LR in that manner

Who knows what their reasoning is. I've learned not to try to make sense of what Tesla does.

I've never been able to figure out a practical use case for Roll. As far as I'm concerned, all it does is replicate one of the few undesirable behaviors of a manual transmission - rolling backwards on a slope if your foot is not on the brake. But maybe I am missing something - what do you use it for?

I find I can do smoother stops with roll. I gave one-pedal a good long try to get used to it, but my stops were just never quite as smooth. My wife is very sensitive to motion sickness, one-pedal was not good for her as a passenger.

How so? Are they jerky or maybe the stop point is misjudged? Its learning that gradually lifting off the accelerator is like gradually applying brakes. People say "getting used to", where it is actually "learning how to".
