Coasting

[Paul K]

I don't know whether it's intentional or not but most of the time when in "D" as opposed to "B" mode when I let up on the accelerator the vehicle doesn't regenerate anything with the power meter showing neither consumption or regeneration. It just glides along like a railway freight car. This is great for 2 lane highways with gentlly rolling hills. As long as you don't have a type A behind one can let the vehicle lose speed going up inclines and then pick up speed on the descent which is the most efficient way to drive in hilly country. Also great around town if you have the space to coast towards red lights hoping they may turn green as you approach.

In true VW software style it is not consistent and sometimes it does regenerate a small amount. And it will not work with the cruise control engaged. I encourage other id.4 owners to try this out and let us know.

Paul have you tested full battery vs not so full battery. Obviousely not going to regen on a a full battery.

Personally I never use "D".. always in "B" and the reason is I dont want to slam into the carin front of me thinking II am in "B" when I'm really in "D"


Had a couple time when I first got my ID 4 that Inearly hit the person in front of me because of that, so yeah I just leave it in "B"


I actually like the regen in the ID 4 , seems to be just strongenough witout throwing everyone forward when you let off the accelerator like my Chevy Bolt would do

Nope. I rarely charge to full. It will coast at any level of battery charge. I used to drive in B mode all the time until I discovered this. B mode is good in heavy urban/suburban traffic with lots of stop and go. Driving in D mode in lighter traffic enables one to hyper mile efficiently without the see/saw effect of B mode. It is very difficult to use the pedal to keep a vehicle from neither consuming or regenerating in B mode. And remember that every charge/discharge ages your battery a little so judicious use of D mode will age the battery less and consume less energy as unnecessary charge/discharge cycles produce more waster heat.

So I'm now using D mode as the default and easily switching to B as the need arises. It would be nice if at least the B mode could bring the vehicle to a full stop the way my 2018 Leaf did. I really liked that feature.
