Daily morning commute MPG

Not so much "confused" as just not correctly informed. ACC on its own applying the brakes makes sense. Good point about no brake lights going downhill with ACC activated, but I've yet to see empirical proof. (I'd have to follow myself or another Maverick with ACC going on.) Might be referenced in a Ford shop manual. Thanks for your input.

I wonder what happens to the extra regen when the battery is full? Is there a big dump resistor somewhere or does the generator stop generating. If there's no generator output there's no slowing effect and you're back to 100% friction breaking.

That's when the infamous engine spinup occurs - potentially up to 4500 RPM I've seen.
Wastes the electrical on engine braking.
If that's not enough - indeed into the pads while that's happening.

Hmmm - I wonder if turning on the AC full blast would help enough.

Is the ACC braking required able to be handled by the regen on it's own?
That's just normal hybrid downhill function to hold speed.
No brake light.

Just like a downshift in normal tranny wouldn't turn on brake light.

Does it require pressure to the pads?
Brake light.

Same as having Auto-Hold on - pressure to the pads - brake light on.

But if brake pedal is pushed to add more regen - brake light.

So it seems to be 2 checks - if brake pedal or if pad pressure - brake lights.

Put something tall in your bed that's reflective - while it was annoying, it made all that very clear. And 3rd brake light is plenty bright when the stupid mirror shoots it right at rear-view mirror!

Thanks for the clarifications.

I've tried.

AC uses 1500 or 2000 watts.

Regen going downhill is 25,000 to 50,000 watts. You can't consume the power quick enough to be very useful. Engine spinup is inevitable.
