On April 16th, automotive blogger "Han Lu" posted on Weibo, claiming to have achieved the fastest 0-100 km/h acceleration time for the Xiaomi SU7—2.95 seconds.
According to the post, the test was conducted on a Xiaomi SU7 Max, fitted with Michelin's highest-performance CUP 2R tires for civilian use. Additionally, numerous improvements were made to the braking system, originally intended for circuit racing at the Beijing Ruissi track.
The blogger discovered a straight-line acceleration track nearby while waiting at the previous racetrack, so they decided to test straight-line acceleration.
At full charge, Han Lu clocked a time of 3.01 seconds in the Xiaomi SU7 Max, making it the fastest acceleration recorded among professional tracks and testing equipment at that time.
In a bid to break the 3-second mark, Han Lu brought in a person weighing 120 pounds for testing, achieving a final time of 2.95 seconds, the fastest recorded across the internet.
According to official Xiaomi data, the Xiaomi SU7 Max accelerates from zero to one hundred kilometers per hour in 2.78 seconds, making it the fastest mass-produced car under 500,000 RMB.
Media and bloggers often conduct tests that differ from official data due to several factors. For instance, Xiaomi Motors states that to eliminate instant start-up interference such as tire slippage and driver reaction time, zero-to-hundred acceleration tests typically exclude start-up time. This approach, widely adopted in the industry, allows for a purer reflection of the vehicle's inherent performance.
In contrast, media tests include start-up time and account for factors like tire condition, road surface, weather conditions, and driver reaction. Consequently, this variation in testing methodology can result in slight discrepancies between the tested data and the official figures.
