Xiaomi SU7 Ultra Zhejiang International Circuit single lap test 1 minute 32 seconds 616

News & Announcements Zhejiang International Circuit March 28

Everyone thinks it is a powerful car that can achieve lap times purely by pulling in a straight line, but the fact is the opposite. It is a real driver's car. Looking around its ranking on the list is enough to explain everything. In the Zhejiang race, no car was slow in 1:33. The track characteristics fully demonstrated the comprehensive capabilities of the vehicle. In addition to the single lap, the durability of the vehicle also surprised everyone on the scene.

Before testing, we had never touched or even seen the real SU7 Ultra. But from the previous waves of enthusiasm, we received a lot of information about it. But after a day of testing and shooting, we found that the previous information was not comprehensive, and there were even some misunderstandings.

Everyone thought it was powerful and flew, and the lap time was purely based on straight lines, but the fact is the opposite, it is a real driver's car. Looking around its ranking on the list, it is enough to explain everything. Pull out all the models that run under 1:33 in the Zhejiang race, and none of them can't beat it! 1:32.616 is the fastest electric car (mass production) we have ever tested, and it is currently the fastest "four-door" and the work with the highest horsepower.

First of all, from the driving posture, I don't feel that it is unnatural to drive. Except that the steering wheel is a little far from the driver (maybe my hands are short), everything else is very good. When driving and brushing laps, a comfortable sitting posture is very important. I don't know if it's an illusion, compared with Max, it feels that the sitting posture is a little lower, and the appearance posture will be much better.

From a subjective driving perspective, the first acceleration in the qualifying mode was a bit surprising, but after getting familiar with it, it felt manageable. The maturity and stability of the electronic control gave people a lot of confidence. It felt easy to drive, but I couldn't feel the car helping me at all. There were too many descriptions and rumors about its high horsepower and acceleration, which made people feel awe and a little worried.

But in fact, it is not a struggling model. The tuning and adaptability of this set of hardware and software are very high. We like to classify its style as comfortable and safe. You can see it by looking at the line and posture in the corners. But it is also because of its excessive acceleration ability that it can produce different running methods while maintaining a stable lap time in the multi-bend track of Zhejiang Race, which is endless fun.

There are many options to adjust in track mode, although due to time constraints, I only adjusted the steering of track mode, and the rest used the default. ABS, ESC, TC, and TVC were not adjusted very finely according to my driving habits, but the feedback given by the whole car was very natural, and there was no feeling of interference with you. I like this very much, which shows that its electronics are smart and flexible enough.

I would like to mention its TVC system in particular. I guess its working principle is similar to LSD, but the inherent advantage of dual motors can achieve a more exaggerated torque difference, which can be said to be an LSD plus version, which is of great help to the vehicle's cornering. Before the front wheels have full grip, the body rotation can come quickly and become very controllable, and will rotate according to the driver's steering.

The overall driving feedback will make the vehicle feel very flexible, not like a 2.4-ton vehicle. When exiting a corner, there will be no oversteer or understeer even if the throttle control is very precise, which means that the driver can control the rotation of the car body through the throttle to gain more time.

What do electric cars fear the most? Low power and high battery temperature lead to loss of power. But on the Zhejiang race track, based on our driving experience, data and experience, to be honest, we did not feel that we could not make a lap time due to low power, nor did the battery temperature affect the power. Because the temperature control of this car is so good that it will not overheat.

Although it can't be run for half an hour like a track day toy, this car can be driven as long as the battery is above 60%, and the brakes will not overheat. This time we tested the SU7 Ultra with the optional racing package, and the brake pads are also resistant to high temperatures. So if you want to participate in the track day, it seems that you can drive it all the time, and it's not impossible to take a break and charge after running a section. Besides, there is also an endurance race mode, which is said to be able to run for a long time. We will try it again when we have the chance.

This car first went through a very strict vehicle inspection process. After a few rounds of on-site testing, we found some unknown/unusual places and feelings, and repeatedly confirmed with the brand's staff that this is the mass-produced version that everyone can buy. Only then will we share our practical experience with you here today.

What everyone may be most concerned about is the chassis performance of Xiaomi SU7 Ultra. As mentioned just now, we are very sure that it is not a powerful model because its cornering performance is also very strong! With the support of Trofeo RS tires, the limit in the corners is very high. Generally speaking, with such a high horsepower, if you don't slow down a lot when entering the corner, you can't exit the corner.

Apart from the horsepower, the SU7 Ultra's lowest bend speed in T4 reached 95kph, which is the cornering performance level of a sports car. In T10-13, which is a special test of the dynamic balance of the vehicle, it can be observed that the roll of this car is very small, and there is a response as soon as the steering input is input. The speed in the corner is also very high.

However, it is impossible to achieve full throttle in T14 and T15. Understeer will occur when passing through with high throttle. I tried full throttle, but it couldn't turn. So the horsepower advantage is weakened. The tail speed of T16 before braking is not the fastest among the tested cars, but it also reached 266kph. The characteristics of Zhejiang Racing not only reduce the power advantage mentioned above, but also magnify its unknown advantages.

However, in a pure straight section like the T16-T1 section, you can really feel the advantage of horsepower. Before braking at T1, the speed reached 231kph, the fastest ever. When braking at the 150m sign, the braking feel is very linear, especially like the braking of a racing car, and the braking force is corresponding to the force given. It is said that the brake pedal can participate in a maximum braking force of 0.6G in combination with kinetic energy recovery. This also effectively helps control the temperature of the Ultra's brake system. It reduces the pressure on the brake system, and the intervention of kinetic energy recovery does not feel non-linear, and it is very natural.

Let’s talk about the shock absorbers of the racing package. Maybe the spring stiffness is a bit too hard for the Zhejiang race. The car has a good response in low-speed corners, but there will be too much bounce. But it is very smooth when passing the curb. I guess this shock absorber is set for the Nürburgring. Maybe for ordinary tracks, it can’t bring out its full performance. I hope that some different settings can be made in the future to achieve better results!

Here we want to say that Xiaomi SU7 Ultra is a well-deserved driver's car. Its appearance, for car owners, in dealing with the use scenario of the track, has indeed completed many functions that electric mass-produced cars could not achieve before, and it has a certain meaning. Whether from the test experience and results, or from the communication with Xiaomi drivers and engineers, we can feel their dedication and professionalism. They made a driving machine with their heart, and we are willing to give it 99 points!

At this moment, the Xiaomi team has officially started the battle in the Nürburgring. We are also looking forward to their good results there. The results of different tracks can allow everyone to see the strength of a car more comprehensively and comprehensively, which is the original intention of the lap time list!
