The Mustang and Lightning both have one-pedal on or off, which is really high or low regen. In addition, they both blend the brakes such that regen braking is used most of the time when you use the brake pedal. The blending of regen vs friction is done based on brake pedal depth or brake pedal application speed.

On the Silverado EV, there are several levels of one pedal regen power. And again, the blending is based on how quickly the driver brakes or how much they brake.

The R2 also has several levels of one pedal. And as far as I can tell, without reading the obd2, the braking is well-blended.

On all of them we choose a setting and don't change it.
Okay so is there a possibility that the Mach E made me nauseous and the R2 didn’t based on the settings?
 
I guess I am confused, as I have only driven gas and diesel vehicles. My only 4 wheeled EV so far is a golf cart.

But with the decent number of ICE vehicles I have had, it is generally a vehicle by vehicle difference on how fast it slows down once you take your foot off the gas. Some have a ton of glide, other do not. You might feel like the ones with more glide are more efficient, but I suspect it is just built in. The glide is probably due to how the automatic transition clutches. Heavier vehicles probably plan on more engine braking simple to save the brake pads. Honestly, sure I use brakes for stop signs, but I try to coast down as much as possible first. See a speed limit sign - just calculate when I need to let off the gas so that I can coast down before the sign.

So my wag is get it all. Allow the EV to have some regen to mimic coast braking on the "gas" peddle. Perhaps make that amount user adjustable, to mimic engine braking. Put some additional regen on the brake peddle, with a fall over to the pads when you need faster braking than regen allows.

Perhaps part of my reasoning is also due to the fact I use cruise control extensively. I try to coast down at speed changes - and I feel like I have failed when my F250 switches from coast down to engine brake mode.

EV's tend to employ a consistent approach to Regen to make it predictable and efficient. When you need faster braking, you just hit the brakes. They are still there for a very important reason - in case you need to stop suddenly.

Recommendation: Test-drive some EV trucks so you can see what OPD is actually like.

The only thing I’ve noticed with the EVs we’ve owned is that when leaving with a fully charged battery, the regenerative braking feels less effective with one-pedal or paddle activation and the regular brake pedal is necessary.

Great call out! When the battery is 100% the vehicle will lower the regen strength because the battery is at max capacity and wont take the additional energy from the regen. This will catch you out the first time it happens once you become reliant on the regen for slowing and braking.

Yes, it's possible. There are all sorts of possibilities about why one vehicle makes you nauseated and another does not.

The R2 makes me nauseated when in hands-free cruise control but no other EV has done that.

Good to know but not ideal. I mean I was nauseous as soon as I pushed the start/stop button. Hadn’t even moved yet. What the heck??

That sounds like a smell thing rather than a driving settings things. Probably some VOC in the Mustang bothered you more than the VOCs in the R2.

If you know someone who has an older Mustang Mach-E with the "new car smell" gone, you might give it a try...

Ahhh, no it was a used one, a 2023 I think and as soon as I sat in it I was like someone smoked in this car and they ran that ionizer thing in it to try and hide it. I bet you that was it because I sat in it, the smell was off and I was instantly nauseous.

New car smell has never bothered me.

Thanks for figuring that out. Makes me feel feel better that it wasn’t the lack of engine.
 
I am a huge fan of having a profile that allows users to dictate the amount of regen. My R2 test drive made my wife massively sick (maybe it was my inadequate OPD or just hitting the accelerator every time I had the chance to experience the torque). Our Wrangler 4xE (which is a plug in hybrid) has two option regular (coast like a trad engine) and max regen (that approximates OPD). For those new to EV having it feel like their trusty 6 or 8 cylinder truck will go a long way to converting new EV owners.

Very true! I never really thought much about it in the R1T because you get a notification / alert on the screen when you start driving that the Regen power is lowered due to SOC.
 
If you’ve driven manual transmission vehicles, one-pedal drive in the Mustang and Lightning, and max one-pedal setting in the R2 and Silverado is very much like driving a manual transmission vehicle with a high-rev lower gear and engine braking to a stop (without the stall at the end of the engine braking). One-pedal off is like driving an automatic and the vehicle just kind of coasts to a stop. The vehicles with in-between settings are a mix of those two.

If a driver constantly moves their foot on the accelerator while driving a gas vehicle, they’re going to do that while driving an EV too, unless they retrain themselves. If they do that, it’s probably better for them to drive with one-pedal OFF.

In all of our vehicles, the one-pedal strength is configurable based on driver profile (which key opens the vehicle first). For a while my partner drove with one-pedal off, but spent a week driving with it on and now prefers it to be on. Its max setting in the R2 is stronger than the on setting in the Mustang, but we both use max one-pedal regen in the R2.

A long, slow, coasting stop with one-pedal OFF will regenerate about as much energy as a shorter one-pedal ON stop will. Neither is necessarily more efficient than the other, if you use them in different ways. But if you coast only for a short distance before applying the friction brakes, you’ll get less energy regenerated into electricity.


The formula is:

kinetic energy is 1/2 mass * velocity squared

Mass and velocity are constant in this example, so the vehicle has the same kinetic energy regardless of how you reduce its velocity. That kinetic energy is either converted to heat (friction braking) or electricity (regenerative braking), no matter how much time or distance it takes to stop.

I knew there would be math! 😹

When I throw time into the mix, things get messier, haha. Braking late and using the friction brakes will save me time, and I value my time highly, but then I've gotta replace the brakes more often, which is also time and money.

I live by the Alabama song "I'm in a Hurry" :ROFLMAO:

This is my lesson learned today. Thanks for sharing that tidbit-hadn’t thought about it that logically

The other issue could be how airtight the new vehicles are and your jeep is by no means air tight so the air pressure could effectively help cause a bit of the motion sickness sensation.

Probably because Rivian's hands-free is all over the place! :p I say that as a Rivian owner who loves the product and recommends it to anyone who asks (and lots who don't) but the hands-free sure leaves something to be desired right now.

Maybe it was because you were sitting in a Ford? :ROFLMAO: I jest, I jest. My dad was a Ford guy. But seriously, maybe it was because it was a Ford?
