On March 25, Fast Technology reported that a video of a Xiaomi SU7 Ultra speeding at 150 km/h and colliding with an electric bike in the city has attracted attention, with the related topic quickly trending on Weibo.

Many netizens expressed after watching the video that it's really terrifying to drive such a fast car in the city, and they will avoid Xiaomi cars in the future.

In the video, this yellow Xiaomi SU7 Ultra temporarily accelerated to nearly 150 km/h. Around 1 minute and 20 seconds in, to avoid a vehicle making a U

Subsequently, a reporter from the Donghu Traffic Police Brigade in Quanzhou City learned that the accident occurred on March 21st. The condition of the injured is currently unknown, and the police are investigating. Further developments are pending.

Experts related to the incident have directly stated that Xiaomi should take a leaf out of Tesla's book, and the SU7 Ultra unlock speed should not be so arbitrary.

At a speed of 80 km/h, the kinetic energy of the vehicle is 4.2 times that of an ordinary family car. The Xiaomi SU7 Ultra, equipped with a 1548-horsepower electric drive system, accelerates from 0 to 100 km/h in just 1.98 seconds. However, this track-level performance poses a deadly risk on public roads.

First, there is a vulnerability in the power limitation mechanism. Industry insiders point out that although new vehicles are required to operate in 'novice mode' (limited to 140 km/h) for the first 300 kilometers, full power output can be unlocked once the mileage requirement is met. The vehicles in question have already exceeded 500 kilometers, completely lifting the performance restrictions.

The Tesla track mode requires GPS localization in a closed area to be activated, whereas Xiaomi's 'Master Mode' relies solely on the driver's self-regulation without geographic fencing restrictions. The Xiaomi 2.3-ton weight and low center of gravity design generate lateral acceleration of up to 1.2G during emergency lane changes, far exceeding the reaction limit of ordinary drivers.
