VW ID.3

On the paper yes, but there's another hidden buffer so in reality it's 54kWh. With up 10% degradation around 3y time it will be even less.

This was my thinking too, the bigger was there so that when someone sells after 3 years for example, their car is still at “100%” capacity, but in reality it’s not - and the person buying the car second hand then sees the effects of the degradation in the following 3 years.

I’m in a similar position to the Mayo poster. I must say that having to do 100kmph on a motorway (the empty M9 in my case), would be what I’d consider an inconvenience.

i assume from what you’re saying that if I set and forget my cruise control to 123kmph as I always do, that there’s no chance of an ID3 achieving 255km in winter?

I don't know how accurate the Car Scanner app is.

But I used it about a week ago and the category "Maximum energy content of the traction battery" stated 51.65kWh.

The car is a 1st with 84k on it.

No source, but was repeatedly told about som3 extra buffers on Volkswagen ID drivers club fb page when the questioned "missing kWh" in my ID.3 1st. I wrote here previously about my 2y struggle with range, battery capacity and my dissatisfactory engagement with the local VW dealer. 2x broken modules from day one... Ps. Aviloo calculates the SOH from 54kWh, not 58kWh. Pss VW SOH test only gives the SOH number w/o quoting numbers used for calculations. At 2.5y my official degradation was approx 6.3%.

Just to add to this there is a big past thread on usable capacity for the ID3 on SpeakEV. The gist of it is as follows

On the official VW Web site there is an illustration for the battery buffers- 4% on top and 6% on bottom

Based on these numbers- 10% buffer total at 6.2 kWh leaving 55.8kWh as usable from new.

To complicate things if you run the battery to zero% you can actually continue driving for maybe another 10km before the car shuts down - so in extremis you can use some of the bottom buffer

Guessing that you can use 2kwh of the bottom buffer then adding this to the 55.8kWh above would get you close to the 58kWh usable which is what is published

You’re not doing great there. Have you recently taken the car to <10% SoC and charged to 100% to allow the BMS “see” the entire range and recalibrate itself?

As a reference my ID.3 1st (202) is at 75k km’s and shows 55150 Wh max, 51600 Wh at 100%

That makes my degradation about 6% after 3.5yrs, which I’m happy with.

Seems like the battery in the ID is standing up well after nearly 4 years. I never noticed any range drop in mine. And hopefully most of the degradation is in the early years of the car. If so an ID should be a good second hand buy. The car itself is well made. Just a pity about the software 😊

I dont get what you are saying there.

What do you mean by "... the next ID3...". Are you comparing to a new one or something else?

I think you might mean the next gen ID.3 which might have more range when new... thus affecting resale value of previous generation? That happens already with ICE so not much different. And there is a reason why manufacturers dont actually display this degradation figure so most people wont know what it is other than seeing the range on the clock when fully charged. So, the price will be more about age, mileage, desirability etc than about degradation... imo.

You need to charge it to 100% as well. Basically the BMS needs to "see" the lowest and highest states of charge.... its only then that it gets a clear picture of capacity. Its still only a snapshot in time but its at least a recent snapshot.

Can you also tell us what your capacity figure is at 100%.... its a separate reading in CarScanner and it will be lower than the max figure you quoted earlier.

How often would you need to cycle the battery? What is CarScanner, a plug in thingy? Would OBDeleven give the same information? Sorry about the questions.

nah, it matters of course but it’s not what is driving it.

imo, the market is just correcting itself from the fallout of inflated prices caused by Covid.

And secondarily, more competition.

Not sure the dimensions agree with that - both Golf and ID3 have same rear width but Golf has more rear head room. ID3 loses the tunnel but overall nothing in them

The VW UK site gives the values. As previous poster said, not much in it. The iD.3 is 4mm wider in the back

Golf

ID.3

There is also alot of extra legroom space in the ID.3 due to the wheelbase (2619 vs 2770(ID.3)) and lack of centre tunnel. Thats where you will notice it most.
