Core Insights - Xiaomi's SU7 L, an extended version of its first electric sedan, has been spotted undergoing road tests, generating significant online buzz. The vehicle features a notably lengthened wheelbase, addressing user concerns about rear space, thus reinforcing Xiaomi's commitment to a "user-first" brand philosophy [1][3][5]. Design and User Feedback - The new design of the SU7 L includes a longer silhouette and extended rear doors, improving visual flow and internal space. This change reflects Xiaomi's responsiveness to user feedback, particularly regarding the practicality of the current SU7 model, which has been criticized for its rear space limitations [3][5]. - The rear legroom in the SU7 L has reportedly reached a level comparable to mid-to-large sedans like the BMW 5 Series or NIO ET7, significantly enhancing comfort for taller passengers. Adjustments to the second-row seatback angle further improve seating posture, reducing fatigue during long journeys [5]. Market Positioning and Strategy - The SU7 L is expected to officially debut by the end of the year, with rear space being a key selling point. Xiaomi is accelerating its entry into the mid-to-high-end electric vehicle market, with the extended wheelbase potentially indicating larger battery capacity and improved range, positioning it against competitors like XPeng P7 [7]. - This upgrade reflects Xiaomi's pragmatic approach in a highly homogeneous electric vehicle market, where comfort is becoming a crucial differentiator. If priced competitively, the SU7 L could attract family users and help Xiaomi transition from a "tech enthusiast" brand to a "mainstream comfort choice," revitalizing the electric vehicle market by 2025 [7].
