On the morning of November 28th, Lei Jun unveiled the results of an extreme endurance test for pure electric vehicles conducted by DCD Auto. This comprehensive assessment encompassed popular models within the 200,000 yuan price bracket, as well as those priced between 100,000 and 150,000 yuan. All vehicles underwent rigorous real-world testing under standardized highway driving conditions. Notably, the Xiaomi YU7 emerged as the leader in endurance performance across the full-range highway test. Despite being equipped with a 96.3kWh battery and boasting a CLTC-rated range of 835 kilometers, it achieved an impressive actual travel distance of 420 kilometers, translating to a range completion rate of 50.30%. However, the Xiaomi SU7 stole the show with the highest range completion rate. Sporting a 73.6kWh battery and a CLTC-rated range of 700 kilometers, it covered 384 kilometers in the test, attaining a remarkable completion rate of 54.86%. This feat allowed it to surpass similar models, including the Tesla Model Y, Model 3, and Li Auto i6. The test also shed light on notable disparities in energy consumption control among different models. Some vehicles saw their actual range or range completion rates compromised due to issues related to body aerodynamics, electronic control strategies, or thermal management systems.
