一汽丰田高管点名小米汽车“轮轴比”算错数：这个概念是雷军“发明”的

Group 1 - Zhao Dong, an executive from FAW Toyota, publicly criticized Xiaomi Auto for incorrectly calculating the "wheel axle ratio," stating that the ratio for the Xiaomi YU7 is 4, not 3 [1][4] - Zhao emphasized that the concept of "wheel axle ratio" was invented by Lei Jun and does not exist in automotive theory, asserting that a ratio of 3 is unrealistic for passenger vehicles [4][6] - Following Xiaomi's promotion of the wheel axle ratio, many companies began to claim their vehicles also had a ratio of 3, which Zhao mockingly compared to students copying incorrect answers during an exam [6][8] Group 2 - The term "wheel axle ratio" gained popularity in the automotive industry after Xiaomi's promotion, with Lei Jun defining it in a way that lacks professional rigor [8][10] - The lack of immediate criticism from the automotive community after Xiaomi's announcement may be attributed to the complexity of the term, which ordinary consumers do not fully understand [10]
