the "B" position

[SMH]

Can someone please explain to me the benefit of the "B" position for the drive selector?

 

[jaapv]

It allows you to select B3 or B5 without resorting to the paddles.

It's an odd one isn't it?

The "B" position (B0 - B5) determines how much regeneration takes place when you take your foot off the accelerator.

This acts like a brake and slows the car down.

I'm guessing that some people prefer to use the selector lever, because that's what they're used to... to mimic changing down to control your speed as you approach a corner.

Typically I only touch the selector lever twice on any given trip, once to reverse out of the driveway, and then a second time to select the D position to move forward. From that point on, I don't need to touch that control again.

If I'm driving in heavy traffic, I turn up the regenerative braking to the highest level, and drive in "one pedal mode".

The only other times I use "B" modes is if I'm controlling my speed on steep descents, or the opposite, if I want to "freewheel" the car down a descent.

When the car is showing "D" is is still doing some regenerative braking IIRC, it's equivalent to one of the B modes, but I can't remember which one.

The default setting is B2. I only use stronger B settings to descend a slope. Nor do I use B0 for coasting, that driving style is too passive for my taste.

There is a long hill on my way home (fast, dual carriage) with a steep almost 360 slip road off the bottom. If I time it right around traffic with B0 downhill to gain speed and then B5 around the slip road (with my head pressed against the side window and tyres complaining ) I can add 1 or 2 miles to my battery.....

...and its fun.

Does someone know, if you have to drive very slowly and carefully out of a parking space, which B level is the best to do so? B0 or B5? When I start the car, the standard level is B2, but when you're in that level, releasing the brake pedal (not even touching the gas pedal yet), the car start to move and I'm not a fan of that. I don't want the car to make that sudden movement when I release my brake pedal. Do I select B0 or B5 in this situation?

When you reverse out of the driveway, which B level do you use if you have to drive very slowly and you don't want the car to move from the moment you release the brake pedal? B0 or B5? I want full control over my car when I'm in a tight space and don't like the fact that my car start to move from the moment I release the brake pedal. TIA

 

[AndyInOz]

Regenerative braking appears to cut out at low speed, it doesn't bring the car to a complete stop.

I don't believe that there is any difference in which B level you select in your scenario.

Why are you in B mode? B mode has nothing to do with the actual braking system. It controls how much regen you get when slowing down. Just put it in R and back up. My 2019 has a feature called hill hold which leaves the brake on until I touch the gas petal. Its controlled by a button on the center consol

Yes it works exactly like the Innovative pedal, cuts out around 5PMH. I wish it was more like the Tesla single pedal that will stop the car fully.

Whilst it will creep equally in any B mode, it will not be a sudden movement unless you mash the accelerator suddenly.

Going up in B mode will mean you have to press the accelerator further to get the same power output.

ECO mode will map the accelerator pedal to be even less sensitive, so if you are having trouble with being smooth at the controls, consider that and practice.

This useful feature also works well in stop/start queues, so you don't have to keep your foor on the break. It might be called something different to "hill hold".

On my 2024 and imagine tge 2023 and 2025 to get the best efficiency in city driving I use B0 so that zi can get the best EV Range In EV Mode. I use the left paddle to slow down gradually by using B1 and B2.

But if my Main Battery has more than 55% State of Charge, paddling to B3 or higher, causes the ICE to start up. tge ICE will continue to run or spin for another 4 minutes before car goes back to EV Mode.

Using the B paddles to use up kinetic Engery to charge up tge battery, rather than using the brake Pad is great because the Regenerative Braking does place a charge on tge Battery.

One thing to keep in mind is that the amount of energy recouped by Regenerative Braking in slowing down is not as much Energy saved by allowing the car to coast as coasting allows the car to maintin its speed. When the car is allowed to slow down a greater amount if energy is required to bring the car up to speed again.

Regenet Braking is great to use when going downhill to slow the car without using the brakes. Also great to slow down to help tge car to stop.

But for traveling where no slowing down is required or at highway speeds, the B0 should be used if one wants to drive efficiently

In stop and go traffic or when the road is covered in snow or Ice I do prefer to leave the car in D or B2 because I believe that this is the safer mode to travel in these conditions.

The feature is called auto hold.

Put your goot on the brake pedal. Select D or R. Turn the auto hold off. Release the handbrake. As you slowly take your foot of the brake pedal the car will start to move. This is very controlable.
