Did autopilot fail? Xiaomi SU7 crash kills three, founder pledges full cooperation
- The Xiaomi SU7 was on Autopilot mode when it crashed and was going at a speed of 116 kph (72 mph).


A fatal crash of a Xiaomi SU7 electric sedan killed three people on March 29. The high-speed crash has emerged as the first major accident connected to Xiaomi's recently launched EV, raising suspicions about the vehicle's autonomous driving system.
According to a report by Reuters, the SU7 was on Autopilot mode when it crashed and was going at a speed of 116 kph (72 mph). The driver tried to regain control despite an obstacle alert presented by the system and attempted to slow down. Unfortunately, the car still crashed into a cement pole traveling at 97 kph (60 mph), with reports saying that it caught fire on impact. Early reports also indicated that the car key did not unlock the doors, further raising safety issues.
