Xiaomi Smart Super Factory: 40 SU7 EVs Every Hour; 76 Seconds to Build One Car

How long does it take for the Xiaomi Beijing factory to build one of its new electric sedans?

The Chinese manufacturer is banking on the assembly being fast enough to seriously disrupt the market.

Xiaomi, known for its smart devices, is venturing beyond consumer electronics with its first car, the SU7. The electric full-size sedan was unveiled in March 2024. The manufacturer started taking orders the same day.

The SU stands for “Speed Ultra.” There are three versions available: the SU7, the SU7 Pro, and SU7 Max.

Founder and CEO Lei Jun claims the Xiaomi Smart Super Factory can build 40 SU7 cars per hour. So a new vehicle could roll off the production line every 76 seconds.

According to Auto Evolution, more than 700 robots operate throughout the factory.
In the body shop, 20 human workers are assisted by 381 robots, with eight bots per workstation.

Elena Luchian writes, “From the moment the parts are picked up until they are assembled to the car body it takes less than 30 seconds.”

Codenamed MS11 during its development, the design was led by Li Tianyuan, who previously worked for BMW. It was benchmarked against the Porsche Taycan and Tesla Model S.

The SU7 is entering the market after a $10 billion investment announced in 2021.

Xiaomi’s plans are ambitious. The Beijing factory has an annual capacity of 150,000 units. With Phase 1 of production on track, Xiaomi aspires to enter the top 5 global car makers.

Production times for Teslas vary, with reports of the Model Y taking just 45 seconds at peak manufacturing speed. Tesla has a level of automation and digital maturity other manufacturers aspire to.
The SU7 is priced strategically to undercut Tesla’s Model 3, whose sales have benefited from local production at Gigafactory Shanghai.

According to Reuters, Xiaomi reported receiving nearly 90,000 preorders within the first 24 hours of its availability. The BBC reports that buyers have been told it may take up to six months for their vehicles to be delivered.

Xiaomi has no plans on attempting to penetrate the North American market with its EV sedan, according to Inverse. Rather it will focus on competing in China with Tesla and BYD, the top selling electric vehicle maker.

BYD’s focus is on expanding into international markets in Australia, Brazil, and Europe.
