I don’t get it. The disks aren’t the harmful part of the brake particulate. It’s the pads. This doesn’t seem to address pad wear as the primary source of brake particulates.
Am I missing something?
You’ve basically answered your own question. The pads are the primary source of brake particulates, the disks are the secondary source. They are both harmful.
Pad wear has gotten a little less harmful since using asbestos in them was banned, only time will tell what effects the substitutes for asbestos might have, and they still generate lots of particulatess anyway.
But as far as I know little to nothing was done as yet to address disc wear. Maybe not a big breakthrough, but every little bit helps.
Granted, the most interesting effect is the weight reduction (which will promptly be eaten up by adding more superfluous gadgets to cars, but…) and that they’ll probably last longer.
I’m not sure I buy the ‘EVs hardly need to use their brakes’ bit. Considerable less than ICE-powered cars, yes, but by that much? My very limited experience with EVs is driving around town in an E-Smart one a month in terrain that is quite hilly, and I find that I really need the brakes. I’m big on anticipatory driving, but gravity is gravity.
Anyway, if EVs spew less particulate it’s another big pro for them.
Generally unknown here in the US, Abarth competition vehicles achieved a spectacular win record in their class for hill-climb and track racing.Over a ten year period, their cars set 113 world and European records on the Monza circuit. Here’s the 1969 Abarth 2000 Sport Spider (with Fiat engine).
An ultracar, they said.
For those unknowledgeable of what rally racing is like… it’s (quite often) super-high performance beefed-up vehicles going balls-out on roadways meant more for tractors.
What’s the point? That car is so low, you couldn’t even lap the Nurburgring in it without leaving half the car behind on the track.
Rally? More like back country drift.
Looks like fun but bystanders are flirting with death.
That’s fairly sensible by rally fan standards. Check out the old group B footage from the 80s.
The crowd reaction shots were a bit much.
