Yes, the best efficiency is having no regen when you lift your right foot. But this is not possible in the Bolt EV, unfortunately.

Regen can only regain a fraction of the energy - probably less than 50% at best - so when you want to carry speed, then feathering the accelerator only putting barely enough power to keep going, is the best. Think of how you would ride a bicycle - and do that.

Agreed, and totally understand that the most efficient driving in the world would be to never touch a brake pedal or have regen slow the vehicle down, but the reality of living in a city with lots of cars is that (relatively) rapid acceleration and deceleration are necessary and unavoidable.

The OP was asking about driving on the highway, so coasting when you lift your right foot (like in the VW ID.4 and optionally in the Kia and Hyundai) is going to be more efficient.

Bolt's regen efficiency appears to be around 70-80%, but your main point still stands.

I get >11 kw power from CC slowing down my 2023 EUV. See the below image. (Sorry it's blurry...) Perhaps the 11kw limit is only for cars with adaptive CC? (Mine is a LT trim - no adaptive option.)

@garyd9 odds are the GM engineers fixed their mistake on the '22 and that's why it's working for you. Perhaps there's a software update available for mine, but I haven't heard of one.

Either that or AEB uses very high amount of regen, because there's a line of trees dead ahead.
