Quite an informative and easy to understand article on the brake system.

Brake or coast? The ID.4’s Intelligent Energy Recuperation Concept

Maximum energy efficiency lies at the heart of the strategy In position D, the vehicle coasts in the majority of cases once drivers take their foot off the accelerator pedal Brake energy recuperation during thrust up to 0.13 g, close to 0.3 g when braking Strong wheel brakes, lifetime linings on...

I hope they will have a toggle to override the coast option. It's only "predictive driving" if you are coming from an ICE vehicle. Neither D or B will let you one pedal drive and if you are used to one pedal driving, this system will cause a lot of panic stopping (something I can attest to every time I drive my wife's ICE car expecting it to slow down when I get off the accelerator). The article makes it sound that "Volkswagen does not want to irritate customers" by giving the customer the option of one pedal driving. I was irritated just reading the description.

Sorry to hear that.

Which is the market that VW is going for in the ID.x vehicles. They want the car to be as ICE like as possible to attract the most number of buyers. They are not going for the experienced EV crowd. I for one applaud them for designing the car this way.

I agree, thank you for posting this. I had been seeing hints that this this was the way the system worked, glad to see it all laid out in one place.

I have no issue with them dumbing down their system, I just wish they have an option to allow for one pedal driving. They already have two different drive options, might as well as one for one pedal driving.

Hopefully, this is an OTA update in the future

The Rep during our demo said all modules can receive OTA. Customizable regen for one pedal driving were a handful of feedback I provided and he wrote down notes to pass on to eMobility team. If they get overwhelming feedback on this from the demo tour customers', maybe they'll consider for OTA update in 2021.

Do we just tweet Ralf or Herbert for the OTA? (Or is that an Elon thing )

Unfortunately, I think US VW HQ folks are the ones deciding what we get or don't get in the USA until Chattanooga starts in 2022 maybe to save on import fees. I told my sales Rep that I'm depositing early next year IF we can get some answers(OTA updates for regen braking, heat pump as dealer add-on, 360deg view cameras, HUD as accessory add-on, etc).

 

[TT97]

Got it, so tweet Scott Keogh.

The one pedal and regen decisions are probably coming down from Wolfsburg. The idea for the early ID's is to make the transition from ICE VW to BEV VW more natural.

That being said, I'd love these as "power user" options. Most of my driving would benefit greatly from both.

 

[air]

Exactly, keep the "D" and "B" for the new ICE converts but allow a super user setting in the infotainment screen to toggle between Hi Recuperation/Medium Recuperation/Low Recuperation similar to like the Eco/Sport/etc

Apparently, since id4 uses regenerative braking on the rear axle, too hard regen can be a safety issue. It maxes out now at -1.6m/s2. VW said, if I remember coorectly, that they could do - 1,9m/s2, but that may still not be enough for one pedal driving.

My BMW i3 had RWD and one pedal driving, so I don't think just RWD is a limiting factor.

It might be a combination with the drum brakes? But why would that be the case.... I guess VW is just overly cautious and safety-minded.

This review leans toward some sense of one-pedal driving in "B" mode:

When it's time to slow down, the brakes feel flimsy and soft, without any real stopping power until you get two-thirds the way of pedal travel. You don’t actually need to use them that much in "B" mode, where VW ups the automatic regenerative braking to slow you down immediately after you let off the throttle. Here it can be driven almost entirely with one pedal.

2021 Volkswagen ID.4 Is for the Early Majority Among Us

We're now well-past the early adopter phase for EVs.

I'll still be driving my wife's GLA on occasion so "as close to ICE" is better for me, but I can understand the more EV experienced desiring one-pedal operation and an option to toggle doesn't seem like much to ask for.

The GLA has the gear shift on a steering wheel stalk which already gives me pause when switching from my more typical console stick layout.

you betta sure nuff watch out n don't get nobody kilt.

That's the entire reason I don't own one. When test driving one a few years back I was crossing an intersection and thought I had slapped the wipers to clear some rain and accidentally put the thing in neutral! Luckily I realized it, and the fix, pretty quickly as we rolled through the intersection. Told my kid, who was riding along, that we would never own one as long as that control layout existed. They really want one to have a single marque household!
