This video recently went viral in China. This blogger was skeptical of all those EVs achieving extremely low drag coefficients including a few “record-breaking” numbers. He wanted to see if his Huawei-branded Avitr really has a drag coefficient of 0.21 as advertised. He took his Avitr to get wind tunnel test and the tested Cd is 0.2818 at 120km/h, 30% more inflated than the claimed number. Now what about officially claimed Cd of 0.195 for BYD U7, 0.199 for Geely E8, 0.195 for Xiaomi SU7, etc? In comparison, Model S has a drag coefficient of 0.208.

PC AUTO, a known Chinese auto publication, recently reviewed intelligent driving systems from eight major brands: Huawei, BYD, XPeng, Zeekr, LI, Xiaomi, NIO and Tesla. In 2 scenarios where a tree is in the way, FSD is the only system that successfully drove around to stay the course. Every other system failed to proceed. For context, FSD is the only system that doesn’t use lidars. Looks like vision-based approach is superior and can solve edge cases which lidars may not.
