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, WEY V9X, Leapmotor D19—all touted the "all-scenario family flagship" tagline, 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 fully loaded. Next, we'll 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 all-new model's body dimensions have seen a significant increase, with the new AITO M9 standard version measuring 5285mm in length, width, and height respectively.
mm × 2026mm × 1845mm, with a wheelbase of 3125mm. The third-row space of the AITO M9 is well-balanced, with a standard legroom of 689mm leading the segment, ensuring ample comfort for regular use. Its interior width of 1396mm and height of 921mm also rank in the upper-middle range. However, its maximum legroom of 810mm falls short of the NIO ES9, and the seat cushion length of 443mm is slightly shorter than that of the Leapmotor D19, putting it at a slight disadvantage in terms of 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, with a wheelbase of 3250mm. The third-row legroom of the NIO ES9 is the benchmark in its class, with a maximum legroom of 1043mm far surpassing other models, offering exceptional 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 is slightly inferior to that of 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 in length, 1999mm in width, and 1800mm in height, with a wheelbase of 3115mm. The Xiaopeng GX excels in lateral space, with an interior width of 1495mm, the highest in this segment. However, its third-row seat cushion length of 442mm is somewhat average, providing slightly 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 in length, 2025mm in width, and 1825mm in 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 use. However, the third-row seat cushion length, interior 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 in length, 1995mm in width, and 1780mm in 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.
Here, we have also compiled the third-row space data for the five models above, making it easy for those in need to quickly compare.
Comparing these flagship SUVs with the "9" designation, it is evident that all of them come equipped with rich luxury features in the second row, delivering excellent ride comfort. However, the differences in third-row space are quite noticeable. The NIO ES9 stands out with significant legroom advantages, the Xpeng GX offers better lateral spaciousness, the AITO M9 delivers a well-rounded overall performance, the Leapmotor D19 provides superior long-distance comfort thanks to its longer seat cushion, and the Wey V9X is relatively conservative, making it more suitable for short-distance emergency use. Additionally, although the highly anticipated "9" series SUV, the Li Auto L9 Livis, did not open for experience at this Beijing Auto Show, we will soon reveal its actual test results. Stay tuned for more updates! (Text/Photos: Autohome Xing Yihan, Photography: )
