Model S [Official] Tesla Model S

Maybe a giant fireproof tarp to stop oxygen getting to the fire.

The battery can produce oxygen itself in a fire, it's part of why they can be so difficult to put out.

 

[TopspeedPT]

That's why I published it because it's the same distance

Like Pirelli says, "power is nothing without control".

A less powerful car with good brakes/tires will be better in every situation.

Teslas have amazing brakes!
Acceleration is not that surprising. Every EV is quick.

One-trick pony...

So , Bjorn Nyland found something interesting .

I , honestly , found pretty odd that brake test. Because , again , brakes are pretty at peak development right now . The only thing that makes apart one from another is size , and carbon ( if you don't want them to heat up as much ; because carbon is worse when used cold ). So that distance in the test was pretty odd

So Bjorn found out why : Tesla was the ONLY one to have Winter tires ! Also , if you watch the video better , you will see that it's the only one that leaves dust behind ( so that track was the worse on that part )

Again , not saying that Tesla's have good brakes . But for a short test , it should not make a difference that much.

Also , the rims on the Tesla , as far as I know , are the standard one , 20 inch. They offer also a 22inch , that should have better braking (larger surface )

Well, they are truly an American muscle car. Dodge, Ford and Chevy used to do this years ago. Especially Dodge in modern times. Add more power, but keep the brakes at minimum stopping power.

Tesla commits to open 7,500 chargers in the U.S. to other electric vehicles by end of 2024

Tesla commits to open 7,500 chargers in the U.S. to other electric vehicles by end of 2024

The Biden administration announced rules and commitments to expand EV charging stations, including cooperation from Tesla, Ford, GM, ChargePoint, and others.

www.cnbc.com

"The Biden administration wants to see at least 500,000 electric vehicle chargers on U.S. roads by 2030, and announced a slate of initiatives on Wednesday to help make that a reality, including commitments from companies that build and operate charging networks like Tesla, GM, Ford, ChargePoint and others.

All of the companies stand to reap the benefits of federal funding if their planned charging infrastructure projects meet new federal standards, which were also revealed on Wednesday.

As part of this effort, White House officials said, they locked a commitment from Tesla to open thousands of its chargers to electric vehicles made by other manufacturers. Until now in the U.S., Tesla Supercharging stations have been accessible primarily to drivers of the company’s own cars.

Tesla specifically agreed to make at least 7,500 of its publicly accessible chargers in the U.S. available for use by any compatible EV by the end of 2024. That total will include at least 3,500 of Tesla’s 250-kilowatt Superchargers located along key highway corridors, as well as the slower Level 2 destination chargers that the automaker provides at locations like hotels and restaurants, the officials said.

Tesla also agreed to triple the number of Superchargers in its U.S. network, with new chargers that will be made in Buffalo, N.Y., the official said. The company has been assembling some of its charging equipment at a facility in Buffalo that was originally intended as a solar panel factory.

Tesla has intended to open up its charging network in the U.S. for years. According to Tesla’s most recent annual financial filing, in November 2021 the company “began to offer Supercharger access to non-Tesla vehicles in certain locations in support of our mission to accelerate the world’s transition to sustainable energy.”

White House infrastructure chief Mitch Landrieu told reporters Tuesday that Elon Musk was one of many automotive sector CEOs involved in discussions with the White House about charging infrastructure last year.

“He was very open, he was very constructive,” Landrieu said. “And at that time, he said his intent was to work with us to make his network interoperable. Everybody else on the call agreed.”

Landrieu added, “It was critically important to us that everybody be included in the conversation.”

Did you even bother to read the post ahead?

I did read the last page, but did read your post now. Valid points.

Problem is, it's not the first Plaid having poor braking. It simply reminded me of the days of older muscle cars. Tesla is continuing an American tradition here.

Yes , but for a short burst like a test , should not have any problems , even if it was called Mustang

The bottom line is they stopped in order of their kinetic energy. The difference in Kinetic energy that the Model X needs to shed compared to the winner is 18%. At best it's brakes are likely 13% smaller and its likely that the contact patch is 10-15% smaller even if they were on slicks. With Performante tyres and brakes it might not have come last... but it doesn't have Performante brakes or tyres.

What I find most interesting is that white number 11 the Model X left.

Winter tyre compounds are softer at low temperatures than high performance tyres that are harder at low temperatures. The Model X's tyres were sticky enough to pick up everything off the runway during it's emergency braking... that's not the case for any of the other cars. Obviously compound stickiness isn't the only factor in winter tyres or they'd be used on performance cars year round, I just thought it was interesting.

 

[Matski]

Kinetic energy? Are you all Scientific and stuff?

Physics is the language of the universe, and maths is it's alphabet, I've studied both... and what I learned was...

... I suck at both maths and physics... maths moreso than physics.

There is nothing odd about it. Tesla has undersized brakes for the weight of the vehicle and the speeds it can easily reach. Everyone knows that with many tests being done and Tesla sucking hard in all of them.

Tesla does have the smallest brakes in the test:

Cayenne GT: 440/410
Urus: 440/370
GLE 63: 400/370
X5M: 395/385
Model X Plaid: 395/365

And that's while it's by far the heaviest. The size of the disc doesn't really matter most of the time because tires are the limiting factor, but if the disc is so undersized that it overheats during a single braking event, then that's a problem. And it's exactly the problem that both the Plaid cars have. If you stop with them from 70mph, it's fine, but if you do it from 150mph (which it can reach in less than 11s), or even 100mph (it seems), the brakes don't keep up.

I am not even sure that having winter tires was a disadvantage in that test. It was done in WINTER after all!

You're pretty much wrong . You forgot that winter tires have deeper grooves that don't do a favor for grip on asphalt

But , if you don't trust me , see this :

Winter tires are ONLY better on snow/ice/mud. On clean asphalt , are worse in almost every scenario...

See the video above dude. Same car , winter rims worse in every scenario.

Almost the same conditions, and the winter tires are 30% lower !

 

[kiki voinea]

I honestly don't get some of you guys. It's pretty clear from the video that the car had issues with GRIP , not braking itself.

In a straight line , only one brake test, ANY brake disc/caliper will stop any rim. It's just a matter of how good the tires are , and how efficient the ABS pump acts.

Also , from the carwow video you can CLEARLY see that the X is on a very dusty part of the track ( you can see the dust behind the car when it brakes ) .

Winter tires + smaller tires ( 255/45 R20 vs 275/35 R22 that should have had in this test ) + dusty cement track = extra bad result

Of course the X would have lost the test ANYWAY , but not that bad !

You don't know what the temperatures were, though. The test you linked only shows summer weather. At low temperatures winter tires become better - that's why you get winter tires on your car. Not because you need to drive in snow. We obviously don't know what the temperatures were in the carwow test, but they easily could have been low enough for the winter tire to be better.

 

[Sunny]

Why guess when you have Internet? The "Tire Reviews" folks have a nice video testing braking cross over temp between different types of tires under wet/dry/snowing conditions -

.

For dry braking, summer tires were best even down to freezing temps.

So I am sure the tires didn't help the X here, but having said that, yes, Model S/X have shitty brakes. Many have complained about it.

 

[pablodav]

Carwow braking test should not be taking seriously. Each driver hits the brakes at a different time with different force. If only they gave VBox results of 100-0 mph, we could make fairer comparisons.

 

[Matski]

Okay. Which bit?

Jesus , I wonder how some of you drive down the roads with this stuff in mind....

Have you ever watched a F1 race during rain? Have you ever wondered why intermids are waaay worse than slicks on a DRY track (if the track is drying and the pilot gets stuck with intermids) ?

More treads = Less contact with the road surface , if the road is dry.

Okay. Which bit?

The same part where Bridster says that "the temperature was better for winter tires"


It does not matter. Any winter tire has more and deeper treads than any summer tire , so less rubber is touching the road , so less traction.

AGAIN: Not saying that Tesla would have got a podium in that test. Just saying that the result is worse because of the rims and tires.

And to ,AGAIN, proof my words :

It does not matter too much in a straight , one only , brake test. Tires will be the judge.

I'm out of this discussion. Keep it your way. Cheers

 

[klier]

This car is all but dead.

But cute conversation nonetheless.

 

[Matski]

The same part where Bridster says that "the temperature was better for winter tires"

I didn't say the temperature was better for winter tyres, I said that winter tyres are softer at lower temperatures than summer tyres. Which is typically a fact, and is potentially a reason for what looks like a lot of pick-up from the tyres on the Tesla, compared to no pick-up on the cars with summer tyres.
