Hello friends!

We were very fortunate to pick up our XC40 yesterday and are working our way through all other configurations. However, we quickly noticed that the One Pedal Driving seems much more aggressive than it did on the models (yes more than one) that we test drove.

Ours has the heat pump, that is the only difference to the models that we test drove.

Has anyone else noticed a change since the software updates?
Thanks!

No change since the software update. But I’ll say it’s easy to get used to it. Just be careful switching to another car. How quick you can forget a “normal“ car.

A reviewer ( cannot remember which ) said you can set the aggressiveness of the one pedal. Not sure if this is true but ...

I did notice when I test drove a P8 last week that it was more aggressive than when I test drove one a month before ( different p8 though ).

I have also noticed that most reviewers say that you only regen in one pedal which as far as I know is not true and that the break pedal blends regen and pads.

I loved one pedal. Cannot wait for my car to make the last 35 miles from the port so I can use it all :)

Took it out for a scenic drive today on some hills & windy roads with a few intersections. Those were good practices for how the "feather" the one pedal. I agree it takes practice but I think I will prefer OPD over the old-fashioned way.

They do say that opd is more for city driving where coasting is less important.

I cannot wait to practice! Ha to re learn to drive at my age! Fun times

Ha! Most people who can afford such cars are old(er). Why does my browser now give me ads for "SUVs for seniors"?

Please more like a muscle car suv for seniors :)

Honestly decking the accelerator at the lights is an almost scary experience ... ( for the 2 seconds or less before you have to stop due to the speed limit. )

I'm a senior and quickly gave up on the OPD. It not only doesn't feel normal, it requires you to keep pressing on the pedal all the time. I do a lot of coasting up to stop lights, etc. My glute would get real tired real fast with OPD. The car does regen with the normal mode. You can switch to that in Settings. Just look at the gauge on the right side of the drive's display. It shows direction and amount of current from the battery. When the color swishes down, it's regenerating, when going up, it's taking power. Even when braking it's mostly just regenerating, not using the brake pads.

Yes, Rat, you are right. Efficiency should be the same, OPD or not. It is just a matter of personal preference. I am glad they give us the option, unlike some other brands.

I'm not so sure about that, and would love to hear from someone who either has real expertise or knowledge on this topic (which would NOT be me-my nerdiness mostly covers history). My general recall based on high school physics would be that any time you try to convert energy (like applying regen brakes), you are going to end up using up some of that energy. The ideal from an efficiency perspective would be that once you get moving as much of that energy as possible goes into moving the vehicle forward. So use your brakes as little as possible and you allow things like wind resistance and friction (axle, wheels, tires on road) to slow you down as much as possible. I would THINK (but don't KNOW) that the ideal would be to use two pedal, but you would need to drive very self-consciously and make sure to lay off the accelerator as far ahead of a stop as possible and apply the brake lightly and gradually. Of course, it's more than possible that OPD would be the same (or maybe even better?) for a driver who is not obsessive. I'm really very curious about this - briefly tried looking the topic up a few months back and didn't find anything. Anyone have anything to add?

We have been using for 4 years now Volkswagen e-Golf. It has no OPD but has the B-mode with the gear selector, which acts similar to OPD. We definitely get more range with the B-mode compared to using the brake pedal.

Everything you said about the physics involved is true. If you hold the go pedal just the right amount such that you are neither accelerating nor decelerating with the motor, that is the same as coasting. If you want to slow down, the OPD scenario allows you to simply lift up your foot and regeneration slows you down. Otherwise, you can invoke regeneration with the brake pedal. The amount of energy put back into the battery would be the same to stop in the same distance. in either case, the mechanical brakes come in to play if you need to decelerate faster than regeneration will allow.

Absolutely true! I had to use a rental car today when my XC40 Recharge was getting the April update and it took a moment to get used to not using the one pedal! Now that I've gotten used to One Pedal driving, I absolutely love it.

I was playing with the one-pedal-drive today in stop-and-go freeway traffic. It does take some getting used to because of how aggressively it brakes, but if you are real gentle on letting off of the accelerator it doesn't jerk you around. Not sure yet that I want to use it. But, I have a question: in OPD, if you let off the accelerator completely and the car brakes dramatically - do the brake lights come on? If not, what warns the car behind you that you are rapidly decelleratiing?

From what I have read the break light comes on any time the OPD is decelerating you which makes sense.

I think if someone redesigned all cars now they would have a sensor which detects deceleration and deployed the break lights.

Speaking from experience from our i3s, the brake lights only come on once a certain g in deceleration is achieved. It's not a huge amount, but if you blend regen with a bit of throttle to coast down to a lower speed you don't get them lighting up. I would assume the volvo has a similar system. In essence it makes people not think you only just passed your test and are always on the brakes!!

When I first heard about one pedal I thought how cool then I realized that we already had one pedal when driving slowly in say an indoor car park using the break and an automatic ICE’s natural urge to accelerate.

How is the same slow driving experience with one pedal? As it is the exact opposite of how it used to be is it as safe?

A shame there is not a one pedal (using the break pedal) slow speed mode to simulate the old way of doing it.
