Plaid still has horrible brakes

What's the braking distance on that mean machine?
The braking distance was OK. However, brakes were definitely undersized for aggressive driving. OE rotors were not of some good quality; they would start vibrating after 10k. EBC was a solution, but expensive.
Keep in mind this is a minivan, with not so eager engine.
 
They couldn't call Brembo or Wildwood for some advice 🤷‍♂️
Hell, even EBC could've come up with something

Is this a 100% pad compound/hydraulic clamping issue?
Or is it just a suspension issue that it gets unsettled during hard braking?
Who the hell is doing chassis development at Tesla?
Tesla puts more focus on the drivetrain and UX. Everything else is an afterthought. They have not updated their platforms in a major way since 2012(S/X) or 2015-2016(3/Y).

Brembo supplied the brakes on the MS/X, the M3/Y looks like TRW(ZF) or a Chinese supplier. A full Brembo swap could be possible, if you can find a cross-reference for carbon-ceramic rotors.
 
The pads were literally cooking with the amount of smoke in that last scene. That being said, are these deficiencies apparent only during track use or can this be reproduced on the street in day 2 day conditions? The last question coupled with, "we are in compliance with outdated but current FMVSS to justify the new brakes," will be how they explain this.

Dont worry, a lot of mfgs use the same excuse for their weak engineering. (RAV4s with side impact engineering only for the driver, F150 base trim levels having no intrusion protection....the list goes on).
 
Don‘t EV’s utilize regeneractive braking systems? I’d expect they are calibrated for normal stopping needs.

Stoping a car going at 100+ mph using energy recovery also requires a battery that can take up the energy as fast as it is generated and generators that can turn the speed into kW’s. That may be an issue. I’ll bet the software is calibrated/biased to recover all the energy at the expense of less than superior braking performance. Anytime the brake calipers are used that’s lost energy, an anathema to EV worshippers.
Ev6 GT addresses this.

Brembo is not an answer to everything. There are obvious advantages to solid calipers. Equally distributed brake power, possibility of larger pads etc.
Problem with Brembo or similar solid calipers is heat dissipation. For example in BMW world, on track, people in E82 135 replace six piston front and two piston rear with ATE calipers from 335 E90. Brembo retain too much heat.
On newer BMW’s Brembo has unique to BMW design with open parts of solid calipers to allow heat dissipation.

IMO problem is size of rotor, particularly contact surface. All Tesla models have undersized brakes for its power. Why? It is unsprung weight. Larger rotor=more power needed to move=less range.

This is not deficiency unique to track. This is 100mph with cold brakes. 100mph with this car is blink of an eye when merging in traffic. Maybe even not intentionally. Anything can happen that requires as fast as possible stop from 100 to 0mph.
The vehicle is grossly under engineered. Other video of Nurburgring lap proves that.

Minimum Viable Product?
 
Question: what was the condition of the brakes before hitting the track?

tesla owners note that the hydraulic brakes rarely see use, and rotor wear is messy due to constant rust… when you finally do need them, they gouge the pads and then need to be re-bedded, which is hard to do in these cars. There’s a great chance the brakes weren’t right at the start. One friend of mine has mentioned annual rotor replacement if you don’t drive it hard periodically to keep them clean.

That is absolutely insane.
This vehicle is 132,000 pounds, or some $150,000. So, you want to tell me that tesla does not have a system that occasionally activates brakes during driving to remove moisture and oxidation like it does in my 2011 BMW and any BMW and MB since 1998?

By the way, as you can see in the video, the vehicle had plenty of hard brakes to re-bed pads.

CCMs are worthless for a street car as they require to be in actual operating temps. They'll probably outlast the car though as long as the disks isn't chipped by debris or overheating.

Probably all the above. Although they use a lot of good technology, they don't have anywhere close to the chassis experience compared to the manufactures in the video.
 
It’s not that they don’t have experience or aren’t capable. It’s just cost cutting and sacrificing everything for range.
There is know-how too. You don’t wake up one morning, decide to make vehicle, and somehow it is as good as others.
The question is: can you make certain car that performs the way you wanted it for that money? Think of Toyota!
They made Lexus LFA. Absolutely amazing performance vehicle. But, they needed BMW for Supra. Why? Bcs. LFA dis not have budget cap. It was “all you can be” product with no cost in mind. They lost HUGE amount of money although the vehicle was super, uber, expensive.
But, problem is to make performance vehicle and still make money.
Tesla decided to make money. You know, “no one makes as much money per vehicle.” There is answer why.
It is all about selling trend.
 
I don't think it is any surprise that I like Tesla, but I think they start to be a less appealing product the higher the price goes. Would I buy a Plaid? I'm not sure. I'd probably rather have the Model 3 Performance even just due to the size of the car. If I was looking to spend Plaid money I think I'd rather try and make the stretch to the Porsche Taycan. Model 3P is a bargain for what it is. The Model X and Model S to me feel like unneeded complication for complications sake and like mentioned these cars aren't really built with the idea of flogging the crap out of it with track use. They just threw the amount of power at it because they could. It was mentioned that because of the power merging at 100mph is much more likely. Sure, I guess that can be true, but it doesn't make that number any less illegal.

Of course I like fast cars and of course I use them to the best of my ability when it's safe to do so in non populated, non busy areas. We don't buy fast cars to brag about them and look at them(some might). There's just a time and a place to do these things and the Plaid has some drawbacks. I still think it's cool.
