Netizens who closely follow Xiaomi's automotive endeavors might remember that camouflaged test vehicle images of the Xiaomi SU7 extended version first surfaced online last year. At that time, the vehicle was in its early road-testing phase, heavily disguised, with limited confirmable details available. Initial observations hinted that Xiaomi was indeed developing an extended variant of the model.

As we stepped into 2026, the frequency of road tests for this vehicle significantly increased. Recently, fresh spy shots have emerged online, offering much clearer insights into the vehicle's stance, proportions, and extended features compared to the previous year. This has gradually shed light on the product profile of the SU7 extended version (internal code name MS13-L).

Clarification: All information presented here is sourced from online spy shots, leaks from industry bloggers, and supply chain news. It has not been officially confirmed by Xiaomi. All parameters, configurations, and timelines are reasonable speculations within the industry and are provided for reference only.

The current Xiaomi SU7 model enjoys enduring popularity due to its high aesthetic appeal, robust chassis performance, stable three-electric system, and comprehensive intelligent experience. However, since its launch, the cramped rear seating space has been a frequently cited drawback by users, making it less suitable for business receptions and long-distance travel with multiple passengers.

Consequently, expectations for the SU7 extended version have remained high. Its primary mission is to overcome the space limitations of the standard version, evolving from a 'personal sports coupe' to a versatile model suitable for family use, commuting, and business receptions.

I. Comprehensive Upgrade in Body Dimensions, Stepping into the Executive Sedan Realm

From the latest road test spy shots, it's evident that the new vehicle's stance is significantly more expansive than the current SU7 model. Industry estimates suggest that the new vehicle may boast a length of nearly 5.2 meters and a wheelbase exceeding 3.1 meters.

For context, the current SU7 model measures 4,997 mm in length with a 3,000 mm wheelbase. With this extension, the vehicle's dimensions now align with those of traditional large luxury executive sedans, directly competing with mainstream models like the BMW 5 Series Long Wheelbase, Mercedes-Benz E-Class Long Wheelbase, and Porsche Panamera Executive Long Wheelbase editions.

According to the spy shot features, the extension is primarily focused behind the B-pillar, addressing the 'effective rear seat extension' that users are most concerned about. The rear door length has noticeably increased, with rumors suggesting that the rear legroom has improved by over 30%, effectively resolving the issues of a cramped rear cabin and insufficient legroom in the current model.

Simultaneously, the vehicle's rear fastback line has been slightly adjusted to feature a gentler arc. This retains the SU7's iconic fastback coupe silhouette without appearing overly formal and dull, while also improving rear headroom. The overall demeanor is now more composed and elegant, suitable for a wider range of high-end scenarios.

II. Rumored Minor Hardware Upgrades, Balancing Handling and Comfort

Based on the details from the road test spy shots, industry experts generally believe that the extended version will be optimized in two key areas: 'making a large vehicle easier to drive' and 'enhancing rear seat comfort.' Given its longer body and larger size, the new vehicle is rumored to be equipped with a rear-wheel steering system to reduce the turning radius, enabling this nearly 5.2-meter vehicle to exhibit more agile handling performance and avoid feeling cumbersome during daily urban commuting, parking, and U-turns.

Additionally, the test vehicle reveals the addition of side radar probes, likely indicating an enhancement to the intelligent driving perception system, improving safety during low-speed travel, lane changes, and parking.

In terms of comfort, industry predictions suggest that the new vehicle will focus on optimizing cabin NVH (Noise, Vibration, and Harshness) performance, with specific adjustments to reduce wind and tire noise to meet the quietness demands of business travel. The rear seats, interior materials, and comfort features are also expected to receive upgrades, emphasizing a more premium riding experience. However, specific functional configurations remain subject to official announcements.

III. Clear Timeline for New Vehicle: 2026 Debut, 2027 Launch as Mainstream Expectation

Regarding the release schedule of the SU7 extended version, after more than a year of gradual leaks, industry information has become relatively consistent.

As early as May 2026, renowned automotive blogger @PS3 Paul exposed a list of Xiaomi's new vehicle plans, which explicitly included the SU7 executive extended version. At that time, it was disclosed that the model would be positioned in the high-end executive market and feature significant upgrades in body dimensions.

Combining subsequent supply chain information, the model's internal code name is MS13-L, with rumors suggesting that the mass production SOP (Start of Production) node is set for mid-2027. Based on Xiaomi's typical new vehicle release schedule, industry experts generally speculate that the vehicle will make its debut in the second half of 2026 and officially launch for delivery in 2027.

As for the model naming, there is currently no definitive answer. Within the industry, it is habitually referred to as the SU7 L, aligning with the naming conventions of luxury automakers for long-wheelbase versions. Alternatively, many believe that Xiaomi may name it the SU7 Executive Edition to further emphasize its business positioning. The final naming remains subject to official confirmation.

IV. Product Positioning Analysis: Addressing Shortcomings, Completing Xiaomi's Automotive Product Matrix

In the current mid-to-high-end executive sedan market, BBA (BMW, Mercedes-Benz, Audi) fuel-powered long-wheelbase models still dominate, while the pure electric vehicle segment lacks a benchmark model that combines 'attractive aesthetics, outstanding handling, spacious interior, and versatility for both family and business use.'

The current SU7 model primarily targets young, sporty, and individual driving enthusiasts, appealing to personal users and young families. The introduction of the extended version will fill the market gap for Xiaomi in high-end business, executive receptions, and long-distance travel with multiple passengers, enabling a more comprehensive product coverage.

If the rumored specifications materialize, the SU7 extended version will offer 'thrilling solo driving, dignified client receptions, and comfortable family travel,' transcending the limitations of ordinary family pure electric vehicles and targeting the high-end market segment priced between 350,000 and 450,000 yuan, engaging in differentiated competition with traditional luxury brands.

V. Authentic Netizen Voices: Anticipating Improvements, Awaiting the Actual Vehicle Launch

With the latest round of spy shot exposures, discussions within the automotive community have once again heated up. Netizens generally express anticipation but maintain a rational wait-and-see attitude.

Many ordinary users note that the current SU7 model has few significant drawbacks, with the sole exception of the impractical rear seating space. Once the extended version addresses this shortcoming, it will essentially become a 'flawless internet-famous model,' suitable for family use, commuting, and making a statement.

Simultaneously, many rational automotive enthusiasts believe that, at present, these are merely road test spy shots, and the dimensions, configurations, and pricing of the mass production version are all subject to change. The actual rear seat experience of the fastback body style, market acceptance in the high-end segment, and final pricing will be crucial factors determining the vehicle's success.

From its initial spy shot exposure last year to its continuous road testing this year, the development pace of the Xiaomi SU7 extended version has remained steady, reflecting Xiaomi's deliberate advancement of its high-end market strategy.

For consumers who appreciate the SU7's aesthetics and handling while also requiring spacious interiors and business attributes, this extended version is worth long-term attention. All subsequent accurate parameters, configurations, and release dates remain subject to official announcements from Xiaomi Automobile.
