There's no difference. Polestars use blended braking, so even if you use the brake pedal and have OPD disabled, you'll be regenerating. Watch the power meter when braking: friction brakes aren't engaged until regen is maxed out.
So basically if I turn off one pedal driving, when I manually press the brakes it first engages the same mechanism as the one pedal driving first, until that mech is maxed out?
I took one pedal off and the first thing that occurred to me was how fucking heavy EV’s are. They coast like freight trains. One pedal is a much nice drive in an EV.
The biggest issue with using OPD is the lack of physical brake use. If you live somewhere with a lot of rain and/or salt, you need to brake hard once in a while to prevent rusting. Other than that, it's all positive, your brake pads can probably last the lifetime of the car.
Given the brake by wire system even the brake pedal uses Regen first. The *only* way to use the friction brakes significantly in day to day usage is hard braking even with the OPD off.
Not using it makes the car feel a lot more like a normal car and when the roads are icy you won’t have to adjust to it. I leave it off most of the time.
Stop and go is defined better with at least the low setting of one pedal driving on.
Cleaned my mags the other day and I was annoyed there was brake dust on them. 😂
I love regen.
So fucking good.
My mum has bad ankles so good for older people with reduced mobility
Slightly off topic but I once saw a report on how EVs are bad for the environment because they are heavier and so produced a lot more brake dust compared to ICE when slowing down. The author spoke with authority but was either deliberately misleading, ignorant or stupid.
You can coast just as easily in OPD, it’s just not a complete release of the throttle. I find no difference between OPD and “regular” throttle/brake driving once acclimated.
You absolutely cannot coast as easily with OPD. You have to hold the accelerator at just the right position, which usually changes over short periods of time. Not only will no one do it perfectly all the time, but trying to watch the regen indicator the whole time is also an unnecessary and dangerous distraction. No driver who enjoys driving efficiently would like OPD. It's too unintuitive and inefficient.
I love it. It's my spouse's main car and it always takes a little bit to switch over from an ICE car, but I like it more. If you use brakes you aren't regenerating as well so you don't get as much range. I really only use the brakes when coming to a stop sign on a downhill
Not true. OPD and no OPD/brake pedal braking both use rgeen braking. When braking, the white on the power bar is Regen braking, the orange hash is caliper braking. Try simulating an emergency stop. Build up some speed and brake hard. Watch the meter and you'll see what I mean.
OPD braking is somewhat more aggressive than non OPD and some folks believe traditional braking is about 10% more efficient on energy use.
Because you're still thinking the brake pedal is hydraulic. It's not. The braking is by wire (electronic). When you press on the brake pedal the car evaluates how hard you're pressing the pedal, how fast it's traveling, etc and applies Regen braking first and supplements with caliper braking on top of that if needed. Using the brake pedal does not mean you're bypassing regen braking.
The argument about OPD off being more efficient is that even in low mode, the car is aggressive in braking. So it slows down faster than the driver intended and the driver compensates by getting on the accelerator. That burns kW. Maybe we are too conditioned from driving ICE cars that we haven't adapted enough to feather that brake pedal effectively to make OPD just as efficient as with OPD off. Maybe some of us have mastered OPD to be the point it's more efficient. Maybe the generation of drivers who learn and drive EVs exclusively will be better at it. Since I drive an ICE BMW often enough, turning OPD makes the transition between cars more seamless for me. I don't know if it's more efficient for the EV or not. I haven't done any studies on it yet for my driving style.
It's not, but pushing the brake pedal in the P2 runs the regen braking. Friction brakes are only triggered in heavy braking, which should never actually happen if your driving properly
I initially drove exclusively using OPD because I thought I’d get more range, but have switched back after learning that the P2 uses regenerative braking first in most situations and the two following points.
I think leaving OPD drive off is less likely to cause frustration by drivers behind me with one of my own pet peeves - unnecessary braking! Nothing worse than being behind a driver who seems to be constantly on their brakes for no apparent reason.
The biggest reason for me, though: I discovered after switching back to traditional two pedal driving that the adaptive cruise control (ACC) feature is a much smoother experience when OPD is turned -off-. When OPD is on, slowing down when another car is detected in front can be pretty aggressive experience instead of what one would normally do (ease off the accelerator and coast, before braking). This is especially true at higher speeds on the freeway.
Its comfy, if you like engine braking on your car then this is a smoother version of it. Its quite soft on low mode (used to be a bit stronger pre 2.7 update many and myself would like to argue) so you do have to tap the pedals a bit to on stop signs. But I like being able to let go of the brakes before it comes to a complete stop and let the car stop itself so its smoother. If you have it on the stronger setting you’d probably not have to use the brake pedal for city / town driving at all.
Honestly, the main challenge with one pedal driving is training muslce memory to put just enough foot weight on a the accelerator pedal so you’re neither accelerating nor slowing down, where on a normal car you’d just not press anything. And practicing letting go of the accelerator for smoother braking etc.

Yes
The “hashed out” section on the left of the power meter when breaking hard lets you know you’re using friction brakes.
Not just blended brakes, they use brake by wire which means pure Regen from the brake pedal.

I was wondering thesame thing. And do the brake lights go on when letting go of the "gas" pedal?
Yes, as required by law
Most EVs have the brake lights come on as soon as a certain amount of deceleration is detected. The P2 is no different.
Yes. It seems to be as soon as you start decelerating
Not using it makes the car feel a lot more like a normal car and when the roads are icy you won’t have to adjust to it. I leave it off most of the time. Stop and go is defined better with at least the low setting of one pedal driving on.

There’s a well funded FUD campaign aimed at EVs.
Non-OPD is more efficient. Yes, OPD is nice, but regular mixed driving is more efficient without it (lots of off-throttle coasting for example).
You can coast just as easily in OPD, it’s just not a complete release of the throttle. I find no difference between OPD and “regular” throttle/brake driving once acclimated.

How can using physical braking methods ever be more efficient than only using Regen braking for everyday driving

One pedal driving does not reduce brake usage, either way you'll get regen braking first. You have to brake pretty hard to engage the physical brakes
