You were probably driving in D mode. Put it in B mode and some of the braking comes from the regen, in D mode it still surprises me how far the travel is. In B mode the brake pedal travel is still long but not so bad.
B mode driving is less efficient that D-mode driving, in B mode you're either maintaining a speed or regenning. In D mode, you can get to your desired speed and coast, when you brake, you are regenning to a certain point, then actually using the brake, just as if you pressed on the brakes beyond the capability of regen in B-mode.

In B-mode you're either inputting to drive or recovering your momentum (at about 80% efficiency).

In D-mode you're inputting to drive, then coasting while preserving your momentum or using the brakes (to instigate recovery). Always more efficient to preserve momentum than prematurely recover it. Just because you press the brake pedal in D-mode doesn't mean you're always using the brakes to slow.

Except when you think you're "coasting" - you're actually either using very small amounts of energy to keep speed or just doing small amounts of regen. Recovery will start when you take your foot off the accelerator - not when you press the brake. Albeit likely tiny amounts.

Unlike a manual ICE you can't disengage the motor and actually coast... the motor is always doing something and either feeding or consuming energy.

I suspect there is little difference between the two in terms of energy consumption - its down to which avoids using the brakes the most - and whether there are any optimum regen patterns (ie is it better to regen more at the start of a slowing down sequence or end). Probably a load of stuff from F1 about the optimum places/speeds to charge up your batteries!!

Personally I like B - it just means less foot left to rightery! :)

On a similar note, I was wondering whether ACC following someone and gently speeding up and slowing down all the time is better (because you're behind someone) or worse (changing speeds) for consumption than just going at a single speed...

D is definitely more efficient than B. Not wasting energy to require regen recovery is more efficient than recovering 80% of it the energy you just wasted. In my personal experience around the doors, I'd estimate there's about 10% in it. Sat on the motorway maintaining 70mph, there'll be nothing in it, and even in B mode, if you're using ACC, the car's operating like its in D mode rather than having the speed drop like a stone because you've not got your foot on the accelerator

Maintaining a speed is always more efficient than slowing (through regen with the ID3) and then speeding up again to compensate, whether it be EV or ICE.

D mode to drive like an ICE auto car, B mode to kind of replicate the 1 pedal driving of a Leaf etc

It isn't, I've tried both on all kinds of routes, I can't match my usage in D mode that I get in B mode.

WE haven't bought an ID3 yet.
I know that, you said you test drove one.

I asked where are your relatives in the world, closest town and where do you travel from?

How often do you do that journey a year?

What's your daily journey lengths like?

I've covered a lot of miles now in an ID3 and charged outside the home etc.
This is the crux of my conundrum. The visit to these relations is only maybe 3 times a year. It's about 120 miles. My daily/weekly journeys are easily achievable with the ID3, so charging at home would be the ideal. I spoke to our electrician yesterday and he says he is having trouble sourcing chargers. Another area suffering the microchip shortage.
Please can you just tell me where you live and where they live? I'm trying to see what the availability of public chargers are either on your journey or near your relatives. Charging at your relatives is going to be pointless. In the depths of winter you will probably only need 50% battery back to go their and back, and even on a 50 kw public charger you'll only need to sit on those for about 30 minutes.

Totally agree re brakes. I’ve had 5 series for the last ten years and the ID.3 is utter crap at braking compared to them. Dangerously so imo. Fine for gradual slow down but I had to brake sharply from 60 last week and genuinely my old car would have stopped in less than half the distance it took the id.3, and that was foot to the floor.

If you drive uneconomically with poor anticipation of the road ahead, leading you to brake late and very hard, using the actual brakes quite a bit (because you override the D mode's desire to use regen to slow for a roundabout or junction with a touch of throttle), then I could see how B might be more economical, only if B has a more powerful regen capability than D does when it regenerates (which it doesn't) or you otherwise use more anticipation of the road ahead when in B mode than D mode. Preserving momentum will always trump recovering wasted momentum and the efficiency of recovery through regen is the same for both D and B.

I find the brakes on the ID3 very sharp. The main difference between the ID3 and my previous BMW is that the pedal throw, on both the accelerator and brake is longer on the ID3. I am sure VW have done this to give you more control over the torque and the braking. One thing I am realising is that the ID3 has been extremely well thought out to deal with the electric torque and a braking curve driven by the different engine type and brakes.

If you are having issues pushing the brake pedal to the floor, you might want to consider adjusting your seating position, you might be to far away to make this comfortable.

The other side of this is acceleration. I never push the pedal to the floor in a petrol/diesel car as after about 75% you are just burning petrol with no gain in acceleration. With the ID3 its completely different, the more you press the more acceleration you get. I have floored the ID3 quite a few times and its great fun.

In terms of B mode, i initially dismissed it but found I am using it all the time now. You just seem much more in control of the car and the accelerating and deceleration phase. i also find i am using the brakes much less, which saves on their wear and tear.

Its a new experience, but its very addictive and makes an ICE car feel rather primitive. My wife was a big sceptic initially, but now feels she wouldn't want to drive an ICE again.

Trust me, I drive better than 99.9% of people on the road. No idea why, but I'm getting better numbers in B. I regularly run up and down the M40 at night with no one on there. ACC set to 70, similar temps, set it to D, set it to B, hardly ever having to touch a brake or accelerate and I get better economy. Must have done it 10 times at least in each mode now. There's not a lot in it, perhaps 0.1/0.2 miles per Kw, but can't get D to be better. Perhaps because it's a particularly hilly motorway because of the Chilterns? I don't know.

Maybe, just maybe if I didn't use ACC and I let it coast down the hill and go over 70 and use momentum to start going back up again this may change things? I can give it a go. But the regen is quite powerful. Keeping me to 70 going down the must be putting a decent amount back.

ACC is the answer to your question. Once you have ACC on, that overrides the need of B to bang on the regen hard to slow you down when you're not on the accelerator. B isn't acting as B when ACC is on.

I only really use ACC when I'm travelling through average speed zones governed by cameras. Most of the time I'd rather come off the accelerator early and slow to a reasonable gap behind the car in front of me in D mode than have the car accelerate in 70 toward a car doing 60 and then it jump on the regen to slow me down. It's got to be more economical to produce just enough momentum than overproduction and then recover most of that overproduction. I'm not really one to make full use of all the driving aids. I feel so disengaged from the assisted driving experience, I'd rather minimise the intrusion of that assistance to save me falling asleep at the wheel through boredom.

What I learned with B is that you can adjust throttle lift to regulate the breaking: if you just completely lift you find yourself breaking too hard but if you lift just a little it starts with a little breaking that can become more intense as you release the accelerator more. I find it extremely comfortable especially at roundabouts or intersections

I'm fairly sure that on B the brakes are never applied (unless you press the brake pedal obvs :) ) - its just regen braking when you lift off.

Anyway - D is fine, but its B for me!

Anyway, the whole point of this thread was to help someone who was considering buying one. And yet even though I asked multiple times where their journeys were going to be from/to they won't tell me, so I can't tell them.if there are any rapid chargers on the route. If you fancy telling me at some point, drop me a message. Very odd complaining about range anxiety when it probably isn't even and issue and then ignoring help.

I am not ignoring you - I am busy with other stuff. Perhaps I wasn't very clear. What I was trying to say, was that one of our non-typical trips will involve a charge top up. If we equate this to using an ICE, it is still an issue with EVs that one has to locate a charger in advance and hope it's working. At this time fossil fuel garages are everywhere and they work. Don't get me wrong, I really want an EV. I am trying to justify it to myself, without having to have an ICE as back up. Where I am going to and from is irrelevant. It's just a journey. Thank you for wanting to help. On this subject of locating chargers, how many apps and subscriptions are actually needed to drive these longer distances?

For longer distances I use zap-map to get an idea of the chargers on the way. i will tend to select one or two options for a stop

I then go to the website of the charger company to confirm the location

although most of the charger providers take PAYG, sometimes this is excessively expensive, e.g.
1. sourcelondon - dont think about it without a subs. The cheapest subs is a £10 one off. Subs take 5 days to register and they send you a key card. Includes parking with payment, so good for central london parking.
2. bp pulse. PAYG ok occasionally. subs is expensive and not worth it unless you are charging with them at least 2 times a month

If you journeys are mostly motorways, i would look for the services ones as they are generally good with the newer ones. Its the opposite of pterol where I would always avoid services as they overcharge for the petrol

Once you are used to it its not bad at all. Also worth buying a mains charger for remote locations (might need an extension cord as well). They are really not bad and can charge 50% of the tank for a short overnight stop

If you will need to plan a charge stop, then where you're going and how you would usually get there (and back) can influence the availability and the providers, which in turn influences whether you need an app or not and whether you need an RFID card or not.

The answer to your question is "it depends", and what it mostly depends on is your destination and route.

The ABRP app is a good one for this kind of thing, for free - pop it on your phone and create a number of different journeys to see what it is you might be contending with.

The reason I ask is because it does vary where you live in the country. I live in Oxfordshire. In the town where I live, as it's located close to the M40, we have 3 x 50kw chargers, 8 x 100 kw chargers, 8 x Tesla Chargers. Bit ridiculous for a small town really. Although I've never used any in my own town, why would I? On my journeys to London and back and around the midlands, due to the upgrade of Electric Highway with Gridserve and Ionity, I have so much choice. Even if they all failed off the M40 there are other 50kw chargers further off, BP pulse or shell. However if you're in say Cornwall... not so much.

Check out Zap Map to see the availability of chargers. What you want to look at are 50kw and above CCS chargers (forget anything Type 2, even if they are 43kw which you can't use). You can filter them in the search.

In 5000 miles with a little planning I've not even had to be concerned, there was once where I wasn't 100% I was going to get back so I stopped on the M40 at Beaconsfield where there are tonnes of chargers for ten minutes, went on my way.

I did help one person in Scotland, their regular journey was a little risky, she was very remote, only two chargers on her journey where she needed it, that would risky.

What I do is just look before I start my journey, where am I going to charge.... check before you leave again and make sure they're working. Don't put all your eggs in one basket.
