If any segments of the highway drive are downhill, you'll recapture some energy even on cruise at constant speed.

- sokoloff 4y agoIt has to be a quite noticeable downhill for a car to net pick up energy at highway speed. Small downhills still require positive power consumption (to overcome rolling and aerodynamic drag). Obviously, there’s a point at which a downslope will offer regen, but these are the slopes where a manual transmission car would pickup speed if placed into neutral.
- djaychela 4y agoThat's not my experience in my renault zoe. Often on almost imperceptible downhill slopes it will be at zero consumption, and there have been many areas where I can't back off the throttle in my ice vehicles where the zoe will be regenning.
- sokoloff 4y agoI find similar at low speeds around town, but once at highway speeds (70-75 mph) in my LEAF, the aero drag means almost imperceptible downhills aren’t going to let the car accelerate with zero consumption.
- kyriakos 4y agoAny downhill steep enough to make you drop gear or hit the breaks in an ICE is a point where an EV would regain energy.
