I wonder how hard it'll be to get the heat out of it though, especially as it appears to be an enclosed unit design... The advantage of brakes at the wheel is that they're exposed to free air cooling, in an area where there might actually be SOME airflow. 

And even then high performance cars often use ceramic brakes, and race cars are known to sometimes have their brakes damn near glowing due to the heat. 

But I love the idea of reducing unsprung weight. That would make suspension tuning more accommodating for both ride quality and handling.

A circular brake pad connected to the motor's output shaft presses against a stationary water-cooled ring within an enclosed system.


I infer it is water cooled per above and probably need a radiator somewhere.  So, the complexity could overwhelm the advantages.

Ahh, I missed that the first time around.

It can probably use the same radiator as the rest of the vehicle. I'm assuming the "stationary water cooled ring" means that the water channels in the ring aren't exposed to the brake pad itself and thus the water won't pick up any brake dust.

In 2024, 88.9% of new car sales in Norway were fully electric, bringing the country closer to its goal of exclusively adding electric vehicles (EVs) by 2025, according to the Norwegian Road Federation.
Tesla, Volkswagen, and Toyota were the top-selling EV brands, with Chinese electric vehicles now making up nearly 10% of new car sales in the country.
Norway's long-standing policy of incentivizing EVs with tax exemptions and penalizing petrol and diesel cars has been a key factor in the shift, despite some levies being reintroduced in 2023.

Cars today often had radiators for the turbo of course, maybe they all do (the compressed air part).  An EV wouldn't have a regular radiator anywhere except for the battery.  They usually have a heat pump somewhere of course.

So, yeah, I'd guess they use the battery cooling system.  

I have wondered idly with our hybrid how often the fiction brakes are engaged.  It's not detectable on brake feel.  I can hear the regen braking happening.

I googled "do electric vehicles have radiators?" before my last response... Turns out they typically do have radiators for various cooling tasks, including the battery thermal management. 

BTW ICEV cars all of course have radiators whether turbo or not. I don't think most turbo cars have dedicated radiators just for the turbo, but some turbocharged performance cars do have intercoolers which cools the air before it enters the turbo.

Yeah my F150 twin-turbo doesn't have an auxiliary radiator, the main radiator is designed to handle it all.  It does use an intercooler.  And it also has a transmission cooler that utilizes the radiator for circulating cooled transmission fluid, which is essential when towing heavy loads.

I think most turbo cars today have intercoolers, specialized radiators for the compressed air.  Our Tucson has one.

An intercooler is a device that helps to cool air as it passes through the engine of a car or truck. By cooling the air, the intercooler helps improve the engine’s performance and prevent overheating. There are two main types of intercoolers: air-to-air and air-to-water. Air-to-air intercoolers use air to cool the air passing through the engine, while air-to-water intercoolers use water to cool the air.

I think of an intercooler as being a kind of radiator.

"I've got to be honest, when Ford badged that a mustang, I thought they had lost their minds, but the more I see vids of people driving them the more I like them. It's like if mustang was an SUV," writes Mark Godston commenting on Ford Mustang Mach-E's success of outselling the gas Mustang in 2024.

Blech

I have no problem with the vehicle itself, aside from my own personal dislike for all of those crossover-mini-SUV looking things.  But it absolutely should not be badged as a Mustang.

Yep. When they first came out it took a minute to get used to the styling, but over time it's grown on me. 

But it shouldn't be called a Mustang.

Somebody in the building has one, so I see it at the charging station at times.  (They apparently did learn how to hook it up.)

I think it looks, well, "OK", but the gas 'stang looks far better.  They should have called it a Pinto.
