I doubt it. Ze Germans are shit about letting you set your own default.
Same for the Koreans. I have to turn on 1 pedal driving in the Genesis every time I turn the car on (or put it in reverse). I understand Hyundais and Kias are the same.

It depends on your local traffic. My area has a lot of lights, merges on county roads, and traffic, so heavier regen means I can capture more energy than my braking. With regen set to level two, I can ease off the throttle and barely use the brakes when traffic is not start-stop but still highly variable, and it doesn't interfere much when traffic is a bit lighter.
My understanding is that braking in an EV is usually brake-by-wire, and depressing the pedal will command regenerative braking up to the limit of either (what the user commands) or (what the battery/motor can handle), adding in mechanical braking only when the regenerative mode can't brake as hard as demanded, or at low velocities where regen can't generate meaningful force.

So the difference, in an EV, between "engine braking" (i.e. releasing the accelerator pedal) and "braking" (depressing the brake pedal) is that it modifies the mapping between pedal depression and commanded action, not that it actually switches between dumping kinetic energy as heat or chemical potential. If you need to dump, e.g., 100kJ of kinetic energy, you're still going to recover (example numbers only) 60kJ into the battery and 40kJ into heat, regardless of whether you do that by releasing the accelerator pedal with light regenerative braking, heavy regenerative braking, or by pressing the brake pedal down.

Well, unless you are in the habit of braking very late and hard so that you perennially overload whatever limit the motor/battery an handle and thus rely on more mechanical braking than necessary.

I believe that's true for my Kia. From what I've read it's not true of all EVs.

I've gotten used to double-clicking the shifter down to B mode in the iX every time.

That would be fine. That's how sport mode worked in my Audi S5 which I did instinctively every time. Our Benz requires you to shift into drive then hit a separate button to get out of comfort mode, which I hate. So long as it's not like that, I should be able to use B every time.

Speaking of, all negotiations are complete with at least one dealership. Another has a couple of days to beat it before I go in and sign with the first on a 2025 i4 e40. I'll be happy to be driving an electric again. Bonus that it's not an SUV and the infotainment system doesn't look like Windows 95.

Comfort/Sport is part of the driver profile in mine. It remembers between me and my wife, along with the seat position, mirrors, etc.

I got an OBD reader and am using ABRP for a road trip from Albuquerque to Palm Springs. We’re going through Joshua Tree on the way out. I should have charged in Needle. ABRP was off by 10% absolute charge remaining due to the mountain crossings. Fortunately Twentynine Palms has a few ChargePoint stalls. I’m definitely going through Phoenix and not remote desert on the way back…

Charging in Arizona has been surprisingly good.

There are Rivian chargers at Joshua Tree but I’ve heard about locking them down to Rivians only so I didn’t want to risk it as I didn’t have the range to get to other chargers.

That is their new flagship and very first 'all EVs' location; I would be surprised if they locked it down. Did you read about that somewhere specifically?

(Older?) Tesla wires the brake straight to the pads and drums so they push aggressively for you to up the regen level, cheaper and simpler that way. Maybe it changed now.

Brake by wire is ancient tech from Prius gen 1, idk why it's so hard for everyone to just do it that way. The pedal has two sections, a electronic sensor part and once pushed far enough, a mechanical link as fallback.

Braking isn't 1:1 since forever anyway since brake assist, it monitors the velocity you stab the pedal and push it to max once it thinks you want to stop ASAP.

Good to know. I hit Twentynine Palms with ~10% SoC out of an estimated 22%. I could have made it to the Rivian charger but I was feeling a bit risk averse. If we go back to Joshua Tree this weekend, I’ll charge there.

On the plus side, 29 Palms Beer is right next to the chargers and by the time I was done with my pint, the car was ready for the last leg.

My current company car is a Volvo S60 PHEV and I'm quite happy with it but the lease will be up by November and the changes in local regulations mean that I should really try and go for a full EV next time around. The i4 and i5 are quite nice but I expect they will be a bit too much on the expensive side and the new Volvo ES90 will DEFINITELY be too expensive for my budget. The new Mazda 6e looks REALLY interesting, I must say. It would be the reasonable choice.

But then...

MG goes and releases the Cyberster and boooooy am I tempted! It looks absolutely smashing with its party tricks and at the same time seems practical enough as daily driver.

Not true in my experience. In my Hyundai (Ioniq Electric) I can set the default regen value to whatever I want for the different drive modes (eco, normal, sport) and then modify with the paddles if I wish. I'd be surprised if the option wasn't there rather than just hidden somewhere non-obvious.

My wife has become accustomed to using the highest regen (level 3) on normal, and I like how it enables more 1-pedal driving with the paddle giving a little more braking when not using the adaptive cruise control.

In case anyone is looking for a relatively inexpensive EV, here are the details of the i4 I am picking up tomorrow. MSRP was just over $60k and they gave me ~$6500 off of that right up front. They took another $9k off with incentives between the fed credit and an employer discount. There were other discounts that would have come close to my company discount but didn’t stack. Then add in the usual, inflated BMW residual. The lease terms work out to a pretty cheap luxury sedan.

My 2024 Ioniq 5 behaves the same as @gregatron5 described; it defaults to Level 3 regen (out of 0-3 plus iPedal) when you start the car and there’s no way to override. I believe it’s an eGMP think, so Kias that use the same platform should be the same.

Yesterday I got rid of my 2018 Tesla Model 3. I liked the car and probably would have bought another Tesla if it weren't for Elon Musk's antics. I replaced it sooner than I had planned because I was no longer comfortable driving it around. Probably a stupid financial decision, but overall I'm happy it's gone. Traded it in for a Polestar 3.

I would like one that integrates into the (smart) meter or have current clamps for the mains connection so it can try to only charge on solar power. Integration at PV inverter level isn't necessarily what I'm looking for.

Here it goes two ways, when some heavy user is on like the oven / induction cooker, charge may need to limit current on some or all of its phases to keep total below 3x 25A. When it's sunny the total available current may be well over 3x25A, which could be used by faster charging cars like the Scenic (3x 32A, 22 kW) or shared by multiple managed chargers. Common size is 3x16A ~11 kW inverter so total available power goes from 18 to 29 kW when it's sunny.

In solar only mode, it should aim for current ~= 0 over the meter.


There are a few chargers that does both, like Wallbox. We call these features dynamic load sharing and solar charging here. Sadly this is a semi car-free neighborhood and I park a minute of walking away, so no EVSE for me.
My old "dumb" charger can be limited to 16A/240V. If so limited, when charging around solar noon, it would fit within the production envelope of the solar panels (3.8 kw system). But the charging would of course be slow, and changing charge rate requires unplugging the charger from the wall and opening it up to change DIP switch settings (really intended only for use when doing initial setup). Many chargers now can have the charging rate changed on the fly using an app or external control panel.

Charging at full rate (32A) is better overnight to be sure that for any reasonable amount of driving the day before the battery is replenished (to 90% controlled by car settings) during the overnight discount period. With Net Metering 1.0 whatever I use overnight for cheap is covered by surplus I produce (at regular off- or mid-peak rates) during the day. Yes, Net Metering ends for me away in 2030 (and is no longer available for new solar - a battery is required now - connections) at which time EV charging will need to be managed differently.

According to the utility's web site, most of their power supply overnight is from gas-fired plants. So from a strictly save-the-planet standpoint I should be charging at mid-day when my solar and others (the utility has a load of commercial solar on-line during the day) are producing. The economics for now strongly suggest otherwise, though. Rate arbitrage ... overnight net of discount is around 9-12 cents/kwh depending on season, while summer mid-peak (early afternoon DST) is around 25 cents. On current rates (not what I have) the credit for surplus production is 4-5 cents/kwh, so that wins as the effective power cost, obviously, for charging in the daytime from solar (probably about double the size of what I now have) without net metering.

Aren't they all like that? My Bolt always starts in Park (duh?) and runs in Drive (minimal liftoff regen, feels like a Turbo Hydra-matic in a Suburban with a V8). One-pedal requires toggling into L whenever you want it, but that's not the default mode. No problem; when out of the driveway, a double-tap into L becomes pretty instinctive.

On my Ioniq 5, and I assume all other E-GMP platforms (Kia, Genesis) there’s just P-N-R-D. Regen modes are controlled by the paddles. The complaint is that there’s no facility to save your default preference. You always start in regen level 3.

Nope, my Volvo is always in one pedal mode, no need for any secret handshake stuff each time. I think it can be tied to a driver’s profile but we don’t use that so not sure. The Volvo seems to not has much fine gradient controls based on what I read here but the one-pedal mode is very smooth and settings remain set which seems bonkers to me that others don’t do that.

“Why the fuck is it built this way” seems to be a near-universal constant with cars. With the clocks going forward last night I was reminded that, although the Kia Soul EV has a modem and defaults to getting time from the mobile network, DST is a manual setting.

Worse, it’s a manual setting per profile. You know, because my partner might not believe in DST and would prefer to remain an hour out of sync with me and the rest of the country, but only while driving.

Firmly in “I cannot even” levels of comprehension.

Both my Tesla and my Polestar stayed in one pedal drive mode once enabled. My wife's Kia EV9 has to be turned on every single time. it's annoying.

I rent cars a few times a month, and it's absolutely wild how many of them are just complete shit with bad UI, terrible defaults, basic things you can't find, and obnoxious behavior that surely no one wants. The "safety" features are among the biggest offenders. I really don't like not knowing how a car will behave or when it might decide that it is going to exert some control over the direction and/or speed of the car.

Lane keeping engages when I’m trying to avoid unexpected road debris. Not helpful. Stuff fell off a truck in front of me and I swerved, and the car tried to push me back into it. I suppose someone can come along and argue I should have used my blinker?

I’ve never had a car be right about its auto emergency braking. The Tesla was insanely stupid about it, literally flinching at shadows. The Silverado I just rented engaged it in parking lots while you were trying to park. I definitely don’t want to have to mash the accelerator when trying to park or pull out of a parking space because I don’t know when the car is going to decide to stop applying the brakes. The I4 doesn’t anticipate that a car is turning or is just crossing and will completely clear the lane well in advance, and will sometimes decide it needs to brake, even though there was no chance a collision was happening.

I also get that a huge portion of people are just staring at their phones now. I see them everywhere, constantly. I’m paying full attention while driving, and am quite aware of what other cars are doing and what they’re likely to do. I will anticipate and avoid everything I can. The cars I’ve driven are all less adept at this than I am.

Honestly, while I might have very much agreed with your assessments about AEB and LKA even five years ago, I find they have (generally) gotten better as time goes on.

I rent cars frequently myself (although it's down a bit from a multiple-year-period where it was several times a month), I still absolutely sit down in every rental car I pick up for a few minutes to go over all the settings, but at least in my experience the safety features mentioned have gotten better.

I will agree with this one tho:

Well Tesla is just bad at vehicle. Most cars with radar based ACC/AEB are perfectly sane.

The explorer (2018) Doesn't have AEB but it does have radar based ACC and over many thousands of miles I can't think of any time it's phantom braked.


LKA shouldn't put enough torque in to matter for a panic swerve.


I do admit that it might be odd in a rental but on a vehicle you drive every day it should only take a few days to understand how it's ADAS works.

My Genesis doesn't just go back L3 regen (instead of staying in 1P mode) when turned off, it seems to do it every time it goes into/through neutral. I live in a city, so I parallel park. A lot. I suppose it switches 1P off so that when you go reverse (you have to have your foot on the brake to change into reverse even if you stopped with one-pedal braking) the car will creep backwards while you're releasing the brake as opposed to having to switch pedals. Stopping the car is much more predictable with the brake pedal than the accelerator pedal. And then when you switch back to drive to pull forward you again can creep with your foot on the brake instead of goosing the throttle.

If the car was in 1P mode it'd be impossible to parallel park without a lot of footwork. With it automatically turning it off when changing drive directions one can park with the brake pedal only.

My biggest problem with the GV60 in this instance is it will brake about 5-6" from an obstacle (usually a car when parallel parking) in front of or behind the car. I often need to get closer to really get into the spot. In order to do that, you have to fully brake, than push the accelerator more than a little to get moving, then super quickly brake again. Super PITA. My i3 is sooooooo much easier to park for a multitude of reasons. This is one of them.

The Genesis does that but… not well. And being a conscientious city dweller, I'd rather not let my car lackadaisically wiggle itself back and forth into a spot while an increasingly long line of increasingly irate drivers wait behind me. Hell, the Genesis often fails to even see the spot, let alone get into it.

Every time I see an iX I think "oooh, I still kinda want one." And then I remember it's a foot and a half(!) longer than my GV60 and get a little sad about the i3 being left to die on the vine. Especially after I had to 3-point turn my GV60 to U-turn and then later the same day just banged out a U in one shot in the exact same spot in my i3. (It was a long day.)
