Lei Jun Admits and Apologizes for Misstatement During Xiaomi SU7 Launch Event

[Company Update] Lei Jun publicly apologized for an inaccurate statement regarding crash test descriptions made during the Xiaomi SU7 launch event.

Core Issue: Confusing Relative Speed with Single-Vehicle Impact Energy

During the Xiaomi SU7 launch event on March 19, Lei Jun stated that two cars colliding head-on at 60 km/h each, resulting in a relative speed of 120 km/h, was "equivalent to driving into a wall at 120 km/h," which sparked controversy. Physically, this claim is incorrect—the kinetic energy involved in a 60 km/h head-on collision between two identical vehicles is only half that of a single vehicle hitting a wall at 120 km/h.

Strategic Intent: Swift Correction to Preserve Brand Trust

On March 21, Lei Jun posted a clarification admitting, "I indeed misspoke," emphasizing that the slide deck did not include this statement, and thanked netizens for pointing out the error. This move successfully shifted public attention away from the verbal slip toward the SU7’s actual test data and safety performance, effectively mitigating reputational risk.
