With regen off you could train yourself to a different driving style, where you coast more. Theoretically that could make a difference.
Yes it does! Now I’m so used to 2 pedal driving. I find it cumbersome to drive 1 pedal. Once you go 2 pedal you never go back!
You are a real scientist Kris! The conclusion is: "there is no difference at all" just a matter of personal preference
in a PS2 - correct - not with other cars
Great video, just the information I was looking for 👍🏼
Good to know it makes no difference which setting you are in, the battery usage will be about the same , even though it feels like the standard setting could be using more electricity on motorway style driving.
Nice test, thanks so much! I will for sure refer to this in the future. It's just a matter of taste then and (according to me) if you enjoy driving or not ;)
Kris - isn't the intention of one pedal driving to regenerate the battery, not provide immediate consumption relieve? Meaning shouldn't the range left be checked after each run to determine the effectiveness of the one pedal regeneration vs regular?
My dream car! Can't wait till it comes to Denmark
Hi Kris, turning OPD on or off but driving the same way naturally doesn't make any difference. Could have you told that before ;) Two Pedal Driving is clearly more efficient if you are able to adapt the driving style to TPD, which means using momentum more and use information you get as a driver reading the road. I have the XC90 Recharge with the 11,8 kwh battery and I did a similar test (although not on my channel yet) and managed to get 48 kms city traffic (in D) vs. 43 (in B). I will soon do a similar test with a full EV and I am pretty sure No-OPD gives much better results with the matching style of driving.
So it is!
As expected. Good job on the test.
Thanks! 😊
Good test it also shows you know the car well. Be interesting if the results would be the same on higher speed twisty roads with low or high traffic. Long coasting and no braking verses regen doing some braking.
Thanks Chris, that was a very useful test. I would also guess that it should be no better with one pedal unless you have a vehicle that does not have blended braking like a Tesla. I believe it’s the only EV without blended braking.
The most effective way of driving would be if you have the one pedal driving off and then drove in a way that made you brake as little as possible. (long distances from other traffic and letting go of the accelerator early to just roll as much as possible to slower speeds instead of braking.
That is how I get the lowest consumption on my Ioniq. :)
I just got one, very interesting video.
I did wonder about this but it seems all down to personal preference. I haven’t got an electric car yet, but like the idea of one pedal driving although I think I would turn it off on motorways unless it was very busy and slow traffic.
Yep, pretty interesting...
Same but different 😀. I guess the battery pack discharges a little bit slower with one pedal activated at least that is the only difference I can see with my Leaf 62kwh.
I think the result is logical. There only would be a difference if you brake harder than 2,2 m/s^2 or 500Nm or 100kW. So the result is always the same just the trigger is another one. One pedal drive „brakes“ automatically and in mode „off“ the driver has to take care to reduce speed. But very nice test run. Also I think the consumption is a very good range now. Thumbs up !!! Go ahead and do more of these videos ;-)
I am awaiting delivery of a EQC and since you have tested that model, would you say that the D-- mode on the Merc gives stronger regen than the Polestar? Also would you say that this result is transferable to the EQC and your own e-tron?
I would argue that while the consumption might not change, your total achievable range would definitely change especially while driving on the highway.
I'm driving a P2 and not using one pedal driving at highway or faster speeds as my feeling is that the consumption might be lower. I've never really measured precisly so no real facts! Could be interesting if you can make the same test but with average speed 100-110 KPH!
As long as the battery is warm enough to take regen, then it still use motors to brake, weather you press the brake pedal or use one pedal drive.
Exactly! As long as you’re not to aggressive on the brake, your will be able to regenerate that way just as good as the car 😊
@@KrisRifa the real question is whether we should turn off one-pedal when most of the journey (90%) is on the motorway. Coasting is something that all cars do when you lift off while on an active cruise control. So it will be interesting to know if Polestar have added some logic (or not) to when ACC and on a motorway (110 km/h) while one-pedal is Standard or Off... another nice test ;-)
Interesting that it does not make any difference to consumption. The only saving is less wear of the brake pads. Good test.
The efficiency is a function of aerodynamics, weight, tires and of the power train / motor technology.
So nicely you proved what was expected. So physics in NO works as in CH or anywhere else.
As since PS2 recouperates always when you go off the pedal (that is what permanent mag mot do by design) - the consumption is nearly the same (as long the iron breaks are not used)
With a smarter motor selection (what most other brands do - but not Volvo / PS) where the car can to real sailing instead of the inefficient push / pull type of mode, you could expect that one pedal drive is less efficient as you generate more re-charging losses than without.
(either energy comes out of the batt or goes in - where you always produce recharging loses).
To be more efficient with two permanent mag motors you would require a gear box (which adds gearing losses, production complexity and cost) to switch of the motors when you don t need them.
The most efficient drive you can have is when the breaking systems (no EL-re-generation or of mechanical ways) are used as little as possible.
So in a state-of-the-art design of the power-train, one pedal drive is what you should not use when you go for higher efficiency and with that for longer range. So as said just basic facts of physics and electro-technical science.
What about highway driving with higher avg speed?
Does it regen as you press the brake pedal when is on '' Pedal Off '' ? Superb content mate !!
Greetings :=)
Pretty much every EV does regen even though one pedal is off, to a certain pressure point, as long as the battery isn't ice cold.
@@Tafsern Thanks man :)
Yes, it does. The Polestar 2 regens until a brake force of 0,3g.
@@rahza92 Not bad !! :0
Thanks for this video! 😃👍🏻
Can you make a video with likes and dislikes with your audi e-tron?
Ex
Ten good things and ten bad. 😃
As for the question about taking the Polestar 2 on a race track, Misha Charoudin did that with one of the engineers, Joakim Rydholm, on the passenger seat: ruclips.net/video/tOgS46o2Pv8/видео.html
Kris Greet video i agee with the conclusion. I hope the one pedal fetish of car reviewers can than stop. One pedal driving with regen set on max does not give you extra range.
Great test, thank you. Two pedal should be more efficient if coasting is used correctly, and it is much relaxing for the accelerator foot. Regen still works, but when brake pedal is used. Works great for me that way. I use both feet in this mode. One for the brake, one for the accelerator.
It should make zero difference in theory. The Polestar 2 always regens regardless of the setting. If you drive carefully any braking mode will regen the same amount.
The only difference would be coasting if not using ACC on the motorway at speeds of 70+ mph ... even then it would be small.
I would suspect, you know, that late braking would make a difference as, you know, the energy would be wasted by using, you know, the brakes instead, you know, of regenerating the energy, you know, back into the battery.
And, you know, one each type doesn’t make a conclusive , you know, test.
Energy is normally not wasted using the brakes on a PS2. With one pedal drive off on a PS2, normal use of the brake pedal will only engage the same regeneration as with one pedal driving. Only very hard braking will engage the disc brakes - and waste energy.
@@perlangseth9406 That’s what I’m wondering about. Late braking means using the brake pads which wastes energy. And if the brakes are being used then it’s not as efficient. Hence my question.
@@SirHackaL0t. I agree. Using the brake pads is a waste of energy. But the brake pads are hardly in use on a PS2 - unless during fairly active driving.
