I did a 101 mile run from Indianapolis to Cincinnati at night. About 85 miles of it is 70mph and I had the car set on ACC with Travel assist. Had A/C on for about 40% set at 75 but then felt to cold so just kept the fan on at low speed. Outside temp avg. was 74 F. Had 3.1mi/kWh until the last 13 miles that I did at 65 mph and then gradually lowered to 35 mph for the last 3 miles.
Trip average according to car was 64mph, dist 101 miles and consumption of 3.3 mi/kWh.
Had a bit of tailwind I suppose and no cars ahead or behind. Fairly satisfied with that result.

Thanks for posting. I'll probably be making this same run some day, just the opposite direction.

Sounds pretty good. Like to see your results on the return run. By the way Indianapolis has a higher elevation than Cincinnati.

I didn't know that. I'll be making the run the other in about 3 weeks. I'll update here how that goes.

I'm still working on whether to use D or B or a mix of both during highway/highspeed driving. I get the feeling that if there's traffic build up or lengthy downhills, switch to "B". While freely driving at higher speeds, keep it in "D" mode. If someone has thoughts pls share. Thanks!

I've tried both on my regular commute to work which is about 20 miles each way. There is barely any difference at constant running speeds. In stop and go though, B is definitely useful. So I end up just leaving it in B and not worry about it.

You shouldn't notice much difference in efficiency between the two. All the regen from B-mode is available via the brake pedal, so as long as you aren't slamming on the brakes in D-mode you will not miss out on recouping electrons. I prefer B-mode in city/traffic because I find the ID.4's brakes to be a bit squishy and non-linear. The instantaneous slowing of B-mode makes me feel more in control and nimble when stopping is more frequent. On the open road I prefer D-mode because I enjoy the feeling of a good long coast when it is safe to do so.

If I am actively using the throttle on the highway, I'll use D mode because I prefer to coast every now and then instead of having to hold the pedal down constantly. But if I have it on ACC, I don't bother changing out of B.

Since ACC is always in 'B' mode when it is engaged, I find that I prefer leaving the selector in D so that, if the situation warrants, I can quickly disengage ACC and coast.

I have had that happen to me a few times where i disengaged acc and regretted being in B mode because of the sudden braking. Is ACC always automatically in B mode?

In ACC the only difference would be how the car reacts when you lift off the accelerator after temporarily exceeding the set speed?

B mode would get you back down to the set speed more quickly although less efficiently.

Redid the run but this time Cincinnati to Indiana at 86F ambient. Overall consumption of 3.0mi/kWh. Not bad considering i had the AC on the whole time at 72F.
