Original · 0 views · 2026-04-26 19:30 · Beijing [Autohome Professional Test] At the Beijing Auto Show, the five "9-series" flagship SUVs — AITO M9, NIO ES9 (parameters|price), XPENG GX, WEI V9X, Leapmotor D19 — all touted the "all-scenario family flagship" label, and the second-row luxury experience and third-row practicality are the core metrics that test their true capabilities. The second rows of these vehicles all come standard with aviation-grade seats, featuring heating/ventilation/massage functions, with premium soft-touch upholstery and stitching craftsmanship that deliver a strong sense of luxury when seated. But in the third row, the differences become apparent: the NIO ES9's maximum legroom exceeds 1000mm, the XPENG GX's lateral width reaches 1495mm, and the Leapmotor D19 has the tallest seat cushion length in its class. These data differences translate into completely different experiences when driving with a full load. Next, let's look at the measured data to see which model better balances the second and third rows. The AITO M9 is positioned as a flagship large SUV, targeting the 500,000-yuan tech-luxury large SUV market. The new model's body dimensions have seen a significant increase, with the standard version of the new AITO M9 measuring 5285mm in length, width, and height respectively.
mm×2026mm×1845mm, with a wheelbase of 3125mm. The AITO M9 delivers balanced third-row space, with a standard legroom of 689mm ranking best in its class, ensuring ample comfort for regular use. Its interior width of 1396mm and height of 921mm also sit in the upper-mid tier. However, its maximum legroom of 810mm falls short of the NIO ES9, and the seat cushion length of 443mm is slightly shorter than the Leapmotor D19, putting it at a slight disadvantage in extreme space and long-distance support. The NIO ES9 is NIO's flagship SUV, targeting premium business and family scenarios, positioned as the brand's largest and highest-spec pure electric model. In terms of dimensions, it measures 5365/2029/1870mm in length, width, and height, with a wheelbase of 3250mm. The NIO ES9's third-row legroom is the benchmark in its class, with a maximum legroom of 1043mm far surpassing other models, offering exceptional spatial flexibility. Meanwhile, its interior height of 938mm also ranks among the top, providing ample headroom. However, its lateral space is relatively narrow, and the standard third-row legroom of 666mm slightly trails the AITO M9 and XPENG GX. The XPENG GX is positioned as a flagship large six-seat SUV, marking XPENG's first full-size flagship model. The all-new vehicle
The body dimensions of this model are impressive. The Xiaopeng GX measures 5265mm × 1999mm × 1800mm in length, width, and height, with a wheelbase of 3115mm.
The Xiaopeng GX excels in lateral space, with an internal width of 1495mm, the highest in this segment. However, its third-row seat cushion length of 442mm is somewhat average, providing weaker leg support during long-distance rides.
The Wey V9X is positioned as a flagship large six-seat SUV, built on Great Wall's Guiyuan S platform. This all-new model boasts standout body dimensions, measuring 5205mm × 2025mm × 1825mm in length, width, and height, with a wheelbase of 3050mm.
The third-row space is primarily designed for everyday basic seating, with a standard legroom of 647mm and a maximum legroom of 712mm, which is relatively restrained and better suited for short trips. The seat cushion height of 332mm from the floor results in a lower seating posture, which may affect comfort during extended rides. However, the third-row seat cushion length, internal width, and height are all at moderate levels, offering a balanced overall performance with no obvious shortcomings.
The Leapmotor D19 is positioned as a flagship large SUV, targeting the 300,000-yuan-class high-value, tech-luxury large SUV market. Its dimensions are 5252mm × 1995mm × 1780mm in length, width, and height, with a wheelbase of
is 3110mm. The Leapmotor D19's third-row seat cushion length of 480mm is the highest in this comparison, providing ample thigh support for a more comfortable long-distance ride. Meanwhile, its standard legroom of 680mm and internal width of 1394mm also rank in the upper-middle tier. However, its third-row internal height is relatively low, making headroom and seating posture somewhat cramped, which is not friendly to taller passengers. We have also compiled the third-row space data for the five models above for your quick reference. Comparing these "9-series" flagship SUVs, it's clear that all of them come equipped with rich luxury features in the second row, delivering excellent ride comfort, but the third-row space differences are quite noticeable. The NIO ES9 has a significant advantage in legroom, the Xpeng GX offers better lateral width, the AITO M9 provides a well-balanced overall performance, the Leapmotor D19 delivers superior long-distance comfort thanks to its longer seat cushion, and the Wey V9X is relatively conservative, making it more suitable for short-term emergency use. Additionally, although the highly anticipated "9-series" SUV Li Auto L9 Livis at this Beijing Auto Show did not open for experience this time, we will soon reveal its actual test content. Stay tuned for more updates! (Text/Photos: Autohome Xing Yihan, Photography: )
