Really prefer low regen, but would like option for brake-only regen and saving as default profile

[Davethadog]

Personally I find it elitist for my ram not to give me gas back every time I use the brake. But in all seriousness, these are engineered systems that have so many variables that I think anyone would be unhappy with the inconsistencies induced by a brake only regen system. Look at how it’s working out for Porsche. Yes the cars drive fantastic, but they also get shit range because the regen is only allowed to work in very defined scenarios.

Yep, hardly ever use ACC or D+ myself (even on 10 hour driving days) but I've never had any problem disengaging smoothly when I did.

Same thing rolling out of the car wash and shifting smoothly from N to D, just need to feather the throttle a little before shifting into D.

The fact that it "tells" you when you've throttle-matched speed is very useful to making it seamless, but I suspect most people didn't know it was a thing

I am very happy with my 2021 eTron and the way it drives with brake regen and optional paddle use. The eTron averages 2.4-2.7 mi/kwh which is right there with Rivian. Range is 222 mi with less than 2/3 the battery of my Rivian. Granted the Rivian is heavier, so more efficient on a weight basis but I would not call the eTron range and efficiency “shit”. I really enjoy driving it. Also if Rivian is going to grow market share they have to appeal to more than the early EV adopters and more on the masses looking for a good driving experience right off the bat. To make a corollary to ICE vehicles, many commenters here are like folks telling me I have to drive a standard transmission when I’ve always driven automatics.

The etron and Porsche use different regen techniques do they not? I know their efficiencies vary, I don’t know a whole lot about the Audi stuff though. I would find a different reason to shit on a Volkswagen group product but I guess now I am forbidden based on joint venture bylaws.

You don't like one pedal driving or manual transmissions?! Geez, what planet are you from?

That surging you’re feeling is also intentional, and I think you can disable it. It’s meant to slow down in curves.

Edit: it’s called Curve Speed Assist and I don’t think you can turn it off … https://assets.rivian.com/2md5qhoea...494a902e66c/r1t-og-en-us-20240527.pdf#page229

Just because one model/brand was unable to implement blended braking successfully doesn't mean it cannot be done.
Porsche and Polestar (and likely others I haven't had the chance to drive hard enough)have excellent braking feel and few drivers can detect the point where the friction pads engage. Porsche eschews one pedal driving and Polestar lets the user decide. I've had the chance to push both standard and Performance (Brembo brake equipped) Polestar 2s on a short track and both have great feel.

An advanced blended system does not sacrifice feel. Gen3 Formula E cars use blended braking on the front wheels (using a motor dedicated to regen) and only regen in the rear. There is no hydraulic or mechanical system in the rear. Drive power is limited to 350 kW, but regen is up to 600kW.

Quite happy with the blended brakes on my Kia EV6 too, and I haven't heard Hyundai and Genesis drivers complain either.

I for one like regen and although it took a little while to get used to it, it's nice knowing that I regain some of the energy used to get the vehicle moving in the first place.

If you have blended braking turned off, then you also handle ever use the brakes...and will likely never have to replace those brakes at $2,000 per corner.

Wow. I think I’m more confused on my Rivian braking than ever.

I’ve seen both sides of these points:

1. High regen setting gets best efficiency/Low regen setting gets best efficiency (and even a mix of both depending on city versus highway)

2. Blended brake setting is a good thing/blended brake setting is a bad thing (driving experience, pad wear, etc.)

3. Highway assist/ACC use regen vs. they don’t use regen - This one is the most confusing to me. I would think it uses regen for efficiency, but apparently the brake pedal is moving and people are seeing brake dust?

Of all the quirks of the Rivian and EVs in general, The Great Brake Debate seems to be the most divisive!

My Audi almost never uses friction brakes when you step on the brake pedal. It uses regen unless severe stopping is needed. You can see that on the display. And honestly, I have never detected it changing from regen to friction. It is so smooth. The only exception to this is a quirk of Audi. Since it locks the brakes when you turn the car off, it also builds up high and low spots when sitting from rust caused by water (like in a rain). The Audi forces friction brakes for the first few stops after starting to supposedly wear this irregularity off. On the contrary, I understand my Rivian always uses friction brakes when stepping on the brake pedal. Plus the Rivian is heavier. Depends on the driving style and terrain, but I could see Rivian brakes wearing out faster than my Audi.
