Xiaomi SU9 Lux Trademark Hints at Luxury Sedan Plans

Trademark Filing Points to a Potential Upscale Sedan

Xiaomi Auto, the automotive division of Xiaomi, may be preparing a new luxury executive sedan under the name Xiaomi SU9 Lux, potentially expanding its lineup into a higher market segment. Details of the trademark recently appeared in a trademark gazette, prompting automotive bloggers to connect the name with a long-wheelbase sedan previously referred to as the Xiaomi SU7L. The company filed the “XIAOMI SU9 LUX” trademark on February 13, 2026, under Class 12, which covers automobiles. The application was published for preliminary approval in issue 1986 of the trademark gazette on June 6, with the opposition period running from June 7 through September 6.

Model Name and Luxury Positioning Remain Unconfirmed

The trademark has fueled speculation about the identity and positioning of the suspected sedan, but it does not establish that the production vehicle will use this name. The connection between the filing and the test vehicle remains unconfirmed, as does the model’s intended place in the company's lineup. The word “LUX” could be derived from “luxury,” potentially indicating a more upscale offering, but Xiaomi has not confirmed that interpretation. Until the automaker provides an official announcement, the proposed name, final specifications, and market positioning should be treated as unverified rather than established product details.

Spy Photos Suggest a Longer Sedan With More Rear Space

Camouflaged test vehicles believed to be associated with the proposed model have appeared repeatedly on Chinese social media. Automotive blogger @出行报告 shared two spy photos, reporting that the vehicle looked noticeably longer than the existing SU7. The blogger estimated its overall length at more than 5.2 meters and its wheelbase at approximately 3.1 meters. These figures are estimates based on the observed test vehicle, not confirmed production specifications. The camouflage also limits what can be established about its final exterior design. No official dimensions or complete technical specifications have been announced, so the reported measurements should be understood as preliminary observations.

Long-Wheelbase Design Could Prioritize Rear-Seat Comfort

The suspected sedan is thought to use a longer body to create additional room for second-row occupants, potentially appealing to executive-car buyers who place a high priority on rear-seat comfort. If this design direction and market positioning are confirmed, the model could provide Xiaomi Auto with another way to move upmarket alongside the performance-oriented SU7 Ultra. Rather than focusing exclusively on performance, a longer-wheelbase vehicle could emphasize passenger space and comfort. However, the spy photos and trademark filing do not confirm the final cabin layout, equipment, powertrain, pricing, or availability, and these details remain unknown until the company releases official information.

How the New Sedan Fits Into Xiaomi Auto’s Lineup

The company's sedan range began with the SU7, which went on sale in March 2024. Xiaomi subsequently launched the SU7 Ultra in February 2025 and unveiled the next-generation SU7 in March 2026. A potential luxury-oriented long-wheelbase model would add another possible direction to this developing lineup, subject to confirmation of its identity and intended role. The existing models establish the context for the reported vehicle, but they do not prove that a new flagship sedan has been approved for production. The trademark and test sightings indicate possible development activity, while the final model name and commercial plans remain unresolved.

Deliveries Show Growth Alongside Recent Sales Pressure

In August 2026, Xiaomi announced that cumulative deliveries of the SU7 sedan series had exceeded 500,000 units in 28.5 months. More recent figures, however, show a mixed sales picture. September deliveries of the SU7 series fell 19.55% year over year to 15,751 units. Across its broader vehicle lineup, Xiaomi Auto delivered 40,015 vehicles that month, its highest monthly total of the year and a 32.71% increase from August, although the total was down 4.61% year over year. These figures distinguish the performance of the overall business from that of the sedan series and show why individual model and lineup results should not be treated as interchangeable.

Expansion Beyond Sedans Adds Another Sales Source

Xiaomi Auto is also broadening its portfolio beyond sedans. Its Sky Nomad extended-range SUV series, launched in September 2026, delivered 12,444 units during that month, providing another source of vehicle sales. The SUV results form part of the wider context for the company's ongoing lineup expansion, while the suspected long-wheelbase sedan remains unconfirmed. If the proposed executive model reaches production, it could broaden the range of customer needs served by the brand, from performance-focused sedans to vehicles emphasizing passenger comfort. For now, the reported trademark, estimated dimensions, and camouflaged test sightings do not establish a launch date, production schedule, or confirmed commercial specifications.

Industry Impact & Outlook

A potential luxury executive sedan would give Xiaomi Auto an opportunity to explore a higher-value segment of China's passenger-car market while diversifying the roles served by its vehicle lineup. A longer wheelbase and greater emphasis on rear-seat comfort could help distinguish the model from performance-oriented offerings, if those characteristics are confirmed in production. The September delivery figures also show that growth across the wider portfolio can coexist with year-over-year declines in both overall deliveries and the SU7 series. This makes future model introductions relevant to the company's product strategy, although their commercial effect cannot yet be assessed. The next meaningful developments will be official confirmation of the vehicle's name, specifications, positioning, and production plans.

Frequently Asked Questions

What is the Xiaomi SU9 Lux?
The Xiaomi SU9 Lux is a possible name for a luxury executive sedan suggested by a trademark filing, but the automaker has not confirmed a production model under that name. The filing appeared in a trademark gazette, and bloggers have associated it with a long-wheelbase vehicle previously called the Xiaomi SU7L. The name and its relationship to the camouflaged test vehicle remain speculative. The trademark alone does not establish the final model name, specifications, launch schedule, or intended market position.

When did Xiaomi file the trademark?
Xiaomi filed the “XIAOMI SU9 LUX” trademark on February 13, 2026, under Class 12, which covers automobiles, according to the reported trademark-gazette details. The application was published for preliminary approval in issue 1986 of the gazette on June 6, with an opposition period scheduled from June 7 through September 6. These filing details establish the reported trademark timeline, but they do not confirm that a vehicle will enter production under the proposed name. Xiaomi has not confirmed the model's identity or commercial plans.

How large could the suspected sedan be?
Automotive blogger @出行报告 estimated that the camouflaged test vehicle measures more than 5.2 meters long and has a wheelbase of approximately 3.1 meters. Those figures came from observations of spy photos shared on Chinese social media, rather than from official specifications published by the automaker. The vehicle appears noticeably longer than the SU7, and its suspected design could provide more room for second-row passengers. However, the measurements remain estimates, and the final dimensions and cabin configuration have not been confirmed.

Why might Xiaomi develop a long-wheelbase sedan?
A longer-wheelbase sedan could appeal to executive-car buyers who prioritize rear-seat space and passenger comfort over a primarily performance-focused driving experience. The suspected vehicle could therefore occupy a different position from the SU7 Ultra if Xiaomi confirms that market strategy. A longer body is believed to be part of the test vehicle's design, but its actual cabin space, features, and intended customer group remain unverified. Without an official announcement, the luxury positioning and the expected benefits for passengers should be treated as possibilities rather than confirmed product attributes.

How did Xiaomi Auto perform in September 2026?
Xiaomi Auto delivered 40,015 vehicles in September 2026, its highest monthly total of the year, representing a 32.71% increase from August but a 4.61% year-over-year decline. Within the sedan lineup, SU7-series deliveries fell 19.55% year over year to 15,751 units. The Sky Nomad extended-range SUV series, launched in September, delivered 12,444 vehicles during the month. These figures describe different parts of the company's portfolio and indicate that monthly growth from the previous month occurred alongside declines compared with the same month a year earlier.

Has Xiaomi confirmed the production date or specifications?
No production date or complete set of specifications for the suspected luxury sedan has been confirmed in the reported information. The trademark filing and recurring sightings of camouflaged test vehicles have prompted speculation, but neither establishes a final model name or a production timetable. The reported length and wheelbase are estimates, and the proposed luxury positioning remains unverified. Pricing, powertrain details, final equipment, and availability also remain undisclosed. An official announcement from Xiaomi would be needed to establish these details reliably.
