Xiaomi SU7 Max Hits 0-100 km/h in 2.78 Seconds—Faster Than a Boeing 737-800

Recently, a comparison between the Xiaomi SU7 Max and a Boeing 737-800 passenger jet in their 0–100 km/h acceleration times has drawn widespread attention. Tests show that the SU7 Max completes the sprint in just 2.78 seconds, while a fully loaded Boeing 737-800 requires 12 to 15 seconds—and even when empty, it still takes 7 to 9 seconds. This stark difference stems from the fundamental distinctions in their powertrain characteristics: aircraft rely on jet engines, which deliver thrust relatively slowly, whereas the SU7 Max, with a curb weight of approximately 2.2 metric tons, features a dual-motor all-wheel-drive system capable of delivering maximum torque instantly from zero RPM. Its HyperEngine V6s motor reaches a peak speed of 27,200 rpm, and combined with an 800V silicon carbide platform, an intelligent chassis, and high-performance slick tires, it maintains consistent launch performance across multiple consecutive acceleration runs without significant thermal fade—demonstrating track-level capabilities. This comparison aims to highlight the inherent differences in powertrain dynamics between ground vehicles and aircraft, not to diminish the value of aerospace engineering.
