HIGH Regen. Loving it!

[Runamok]

okay ... so maybe this thread has got me high-regen curious.

Ever since I’ve had my R1T last March, I’ve been using the standard regen setting. Decided to try High this week, since the .38 update.

I’ve been really enjoying it! I think the high setting gives a lot more tactile driving experience. And the throttle seems to be more sensitive/responsive to the touch.

High recommend giving it a shot!

There’s standard Regen? ?

This is my first EV and it took me all of 5 minutes to get used to one pedal driving. I love it -though I also still enjoy using a good manual transmission. I switched to high regen just to try it after reading a lot of complaints here. I was surprised as it felt great to me. I leave it on all the time now. Once the snow flies I'll experiment to determine if it is less desirable under slippery conditions.

I strongly prefer the high region as it makes it really easy to stop and it's overall a more pleasurable drive. It didn't take long to be able to stop smoothly - just takes practice. Maybe the energy savings can help offset the increased tire wear? I am totally in the "enjoy the vehicle to its fullest" camp and not be always worrying if this or that will wear out sooner.

I tried hi-regen when I first got our R1S (first EV) in March and hated it. Switched to std and stayed that way until about a month or two ago. Now I only use hi-gen and love it. Either I have finally become used to regen or Rivian has tuned the hi-regen to make it work better. Either way, I'm driving only with hi-regen and as others have said, I feel like I can control the vehicle speed much smoother now.

As I mentioned in my post.. I know I would be overcome by the high regen thrill and use it to it's max at all stops.. not feathering which can certainly be done even on high regen. Doing that is like jamming on the brakes 25ft before a stop sign at traffic light.. it will definitely wear out tires faster then feathering or using regen on standard. It's a "me" thing, not a issue with high regen.

Try this: turn off any music, fans, etc.. or anything else that makes noise inside the cab and drive to a quiet area. Then open the windows and get up to maybe 40mpd and completely release the accelerator pedal.. will you will hear the tires struggling to maintain a grip under those extreme deceleration conditions. That will certainly lead to increased tire wear.

Please define *huge tire wear* w/ some data points.

FWIW, I've driven 100% in max regen/sport/lowest/stiffest mode never touching the brake unless absolutely necessary since picking up my R1S w/ 24 miles on it; I just rotated my 22"s last weekend w/ ~11.5k miles on it and all 4 tires were in the 6mm tread range (inner/outer/middle).

Been driving with High regen since day one. It's hard to say without having instrumented some stops, but it really feels to me like they neutered the regen with this last update. While it may be ultimately as strong as it used to be, they delay regen when coming off throttle a bit and it ramps in more slowly. For those actually trying to avoid the friction brakes, I'm not a fan. If I'm right, I wish they'd have called it out in the release notes. The past two updates have seemingly changed the throttle map in AP mode and it's messing with my muscle memory.

I have been imagining recently how you might implement, and what it might be like to have a dynamic tire wear gauge.

It would factor in things like, speed, acceleration/deceleration (including sideways), and turning radius.

Tight, to-the-stop turning is one of the worst on tire wear (just noticed the tread marks you leave). I have long developed the habit of swinging wide when there's room—gaming the maximizing of radius.

setting to high regen does not mean pedal will be totally lifted off every time from 40 mph till 0mph.
I switched to high this week and having some pleasant experiences.

I do notice from the gauge view that, in lower speed (about 10mph and lower), regen only works on front motors, not the rear. Probably for smooth stop experience. but yes does put more stress on front tires in long term

When I picked up my R1T, my guide had already turned on high -regen--I thought it was the default.

This is the first update I got that undid high regen, and I didn't even realize it. Not only did I think the car was driving 'oddly' (and couldn't put my finger on why), but I lost an extra 3 miles of range driving into work that day.

On my way home I was digging thru the new menus and realized that my regen was on "standard."

It's back on high where it belongs

I will also point out that there's not going to be any increased tire wear if you're driving the vehicle the same. High regen doesn't automatically mean you're stopping more quickly, unless you fail to adapt to it and can't drive... Physics remains physics regardless of whether the motors are slowing you or your brakes are.

Newsflash, but most of your braking with friction brakes is done by the front wheels too. If they added too much from the rear (friction or regen) you'd probably spin.

My R1 was delivered with regen set to hi. It has OC interior. After a few near-misses with passengers enjoying their coffee, I have switched to standard and instituted a no-coffee rule in the car.

This discussion brings me back to prior discussions (possibly on another forum or video) about “bedding the brakes”. I have had my R1T for about two months and have not done this. Is there any consensus on this?

 

[Donald Stanfield]

Yeah I started off in high and this was my first EV and it took under an hour to get used to it. High regen is the most precise method of slowing down I've ever seen.

Then again I'm good at driving stick shift so I'm familiar with feathering the accelerator instead of using it as an on off switch. So many people drive like absolute garbage that its no surprise some people have trouble with it. That's 100% a driver skill issue and nothing else.

The system is capable of the smoothest stops and starts of any vehicle I've ever had hands down.

Um.. what??

Words matter... I never said "huge tire wear" anywhere in my post.

I said "increased tire wear".

Carry on....
