I think the more surface area the more stopping power.You only need large brakes after the brakes heat up and they start slipping. You don't need them before that. -Crissa
This isn't exactly true, as pointed out, there are limits to your tires. As long as the brakes can stop the wheel, that's all that matters. And the brakes on an EV are a backup, you have regen to deal with braking.I think the more surface area the more stopping power.
Not completely. A larger brake pad and associated surface area offer a chance to get closer to max deceleration without a lock up. Think of using a pad the size of a bandaid. With enough force applied you can lock up the wheel. But modulating the brakes before that point is tough. Additionally, smaller brakes focus the friction energy (heat) into a smaller point, causing higher temps. Larger pads and rotors offer the chance to spread all that out, and offer a chance at leverage vs the smaller rotor/pad combo. You are very correct that regen is doing most of the work, most of the time. And the beauty here is that instead of converting your energy into heat to be dissipated into the air, an EV converts a large part of your energy to electricity, that you get to use later.This isn't exactly true, as pointed out, there are limits to your tires.

I don’t think they fail to appreciate the art of braking, but the ultimate offerings (net net) do tend to be under-performing relative to the speed and weight of the vehiclesOne photo is not sufficient to persuade me that Tesla's engineers fail to grasp the art of braking.
