Plenty of ICE cars let you control the transmission, and not just MT. Engine braking is effectively the same as regen braking to tires.

Regen is lossy, so there’s no incentive in slowing down to capture 1W just to speed up and spend 1.1W

Porsche has modes for coast and regen. Applying brakes in coast mode will use regen up to a threshold and then use conventional pad/rotor.

So I am sorry to inform you that you’re just wrong.

There are EVs that can coast.

EVs are not braking more.

Whether you use conventional brakes, engine braking, or regen braking, it’s all the same to the tires.



You make a fair point that engine braking is not dissimilar. However the impact of engine braking is orders of magnitude smaller.

The reason to capture 1W and then spend 1.1W is it keeps you at a consistent speed. That's why manufacturers do it.

Lots of people in these comments who have never actually driven an EV while looking at the energy usage readout.

Personally I've never driven a Porsche but I've driven EVs from Nissan, Tesla, VW, Chevrolet, Kia, and Hyundai and they all do this.

So I am here to inform you that you are just wrong. There's no need to be sorry about educating someone, though, don't apologise next time :-)


You should answer for yourself why any of the three stopping methods would result in more or less tire wear than the other.


I have, multiple times, in comments here.

The responses tend to be either "actually regen braking wears tires just as much as using brake rotors" by people who didn't actually read, or "surely manufacturers wouldn't do that, it doesn't match the mental model in my head" by people who've never paid close attention to the power readouts while driving an EV.

Your own response was "actually one manufacturer does have a setting that will avoid the effect if someone sets it, therefore the whole concept must be wrong".
