On July 28, Luo Yonghao questioned the widespread use of diamond-quilted leather seats in new energy vehicles on social media, calling the design outdated and asking whether its popularity stems from designers' preferences or a general market belief that it conveys a sense of luxury. Some netizens expressed support, arguing that mesh fabric ergonomic seats offer better comfort, breathability, and support, while also helping reduce vehicle weight, lower costs, and improve environmental sustainability. Diamond quilting is a traditional interior craftsmanship technique that uses stitching to secure leather, minimizing sagging and wrinkling over time and maintaining a smooth seat surface. Commonly found in legacy luxury brands, this method involves significant handcrafting and is regarded as a design element reflecting high manufacturing standards. Some new energy vehicle makers have also adopted this technique to enhance the perceived luxury of their models.
