No one doubts the effectiveness of the Xiaomi Su7 Ultra. But more and more details that make us ask ourselves if the most special sportsman of the Chinese firm dresses with too much paraphernalia. The last thing we know Apuna to it, with disc brakes that, in reality, hide a minimum size pills.
Gold seems. But stop, it does not seem that in front of everything I should. And it is that the disassembly of the brakes of the Xiaomi Su7 Ultra has shown that what is hidden under its huge housing is, in fact, some little larger brake pills than those of a Seat Ateca.
And, although its housing is huge and stands out behind the tires, the truth is that its brake pads seem to be infradimensive for the weight and power of the vehicle. “There is more decorative clamp that really brakes,” explain our partners from Motorpasion.
Overheating. The clash of influencer tang zhu liao che behind the wheel From an Xiaomi Su7 Max, which mounts very similar brakes, already gave the alarm. Trying to look for his best time in the Shanghai Tianma circuit, the driver ran out of brakes due to an overheating problem, ending in the protections.
The same has happened to an Xiaomi Yu7 Max in Tianjin V1 circuit, they report in Carnewschina. In this case, brakes came to support temperatures above 600 degrees which, again, caused overheating that left them unusable and even burned.
Too small. Criticisms of Xiaomi do not come to lie about their brakes. What happens is that these do not seem to be prepared to endure cars of more than two tons launched at maximum speed in a circuit.
This could be overcome but the truth is that the company has sold its xiaomi su7 ultra as a perfect car for circuit. To the point that he wanted to force his drivers to pass a test as if it were Gran Turismo.
The point is that Xiaomi gives what it promises: Brembo brakes perforated with four pistons. However, its size is much smaller than its housing suggests. And that is a problem because at a lower disc size, It is more likely that overheating will be registered And, therefore, the brakes die along the way. And at a smaller pill size, smaller mordant.
Too spectacular. It is not the first time that Xiaomi takes the colors because the elements of their electrical sports are more spectacular than effective. A few months ago, it was discovered that the competition hood that can be mounted on the Xiaomi Su7 Ultra It has no effect on driving And it is purely aesthetic.
So, Some buyers demanded to the brand for deceptive advertising since they pointed out that it was one of the elements that allowed to achieve a better performance. However, the air intakes of the hood did not refrigerate any component directly and the company promised to withdraw the hood in those cases that, once the order has already been placed, they would not yet be delivered.
Xiaomi defends himself. The most recent event with the Xiaomi Yu7 Max was recorded during a test in the vehicle circuit by various media. The driver, they count on Carnewschinadetected the problem in the brakes and decided to enter boxes to safeguard security.
From Xiaomi, however, they defend themselves by ensuring that this happened because there was no warm -up return before the fast return and there was not a cooling turn before returning to boxes. This caused the combustion of small compounds next to the brake clamp but, according to its version, the performance remained optimal.
They also explain that the return had not activated the Master Mode which activates a regenerative braking of up to 0.2 g that should help stop the vehicle making less use of the brakes.
Is it so much? A little yes. And it should be borne in mind that the most powerful electric cars are, in their vast majority, huge cars because they need batteries that support their accelerations. And that forces to include brakes at the height. The companions of Motorpasion They compare Xiaomi’s Berlina with some rivals. They explain that the Chinese company does not offer concrete data of the size of its discs but it is estimated that they are around 320 mm in the Max and 430 mm versions in the ultra versions.
A Tesla Model and Performancethat with its 530 hp they are far from the almost 700 of the Max and very far from the more than 1,500 hp of the ultra, it has a 355 mm discs, that is, larger than those of the Max version. A Porsche Taycan GTSwhich touches the 600 hp, mount 390 millimeters in front and 358 millimeters behind, with six and four pistons.
But, above all, the difference is in the size of the pills. Not only that disc brakes are also smaller or are not so sized for power. The other big problem is that the size of the brake pill seems to approach that of a Seat Ateca instead of a supercar of more than two tons. And that, when you turn a circuit, it’s a problem.
