Xiaomi Auto is moving fast after launching several models this year. Now, a camouflaged large sedan prototype has been spotted in China. It seems to be their next big step—a flagship executive sedan that may carry the name SU9 Lux.
Prototype Matches Executive Car Size
Photos shared on Weibo show a heavily camouflaged prototype about 5.2 meters long with a wheelbase near 3.1 meters. These dimensions fit right into the executive car segment in China, offering plenty of rear legroom. This model would be larger than Xiaomi’s SU7 and close in size or even longer than the Audi A8 available in Europe.
The prototype also appears to have rear-wheel steering and extra sensors or camera spaces along the sides, which could help this long sedan maneuver in tight spaces.

SU9 Name Suggests Flagship Position
Xiaomi filed the trademark for the name SU9 Lux in February, alongside SU7 Lux, indicating a possible luxury trim for the current SU7 or brand protection. The number “9” is widely used by Chinese automakers to mark their top models, like Zeekr 9X and Nio ET9. Other brands such as Audi and Hyundai also use “9” to signify their largest flagship vehicles.
These clues point to Xiaomi positioning the SU9 Lux as their most luxurious, high-end sedan to date.

Xiaomi’s Broader Lineup and Market Moves
After the market launch of the SUV SU7 earlier this year, Xiaomi’s sales have cooled somewhat, with a nearly 20% drop in September. However, overall sales remain strong thanks to the YU7 SUV and the newer Sky Nomad SUV line, which features extended-range electric setups.
The rapid pace of China’s market means new models quickly take attention away from older vehicles, pushing Xiaomi to develop fresh entries like this executive sedan. The company plans to enter the European market in 2027, starting with Germany. The SU9 Lux may play a key role in this global expansion.
So far, Xiaomi has not released official details on this sedan. The prototype’s testing and trademark filings suggest the model is still in development with more information expected before launch.
