China's record winter EV test in Inner Mongolia put 67 cars through seven challenges at –10°C to –25°C. Top performers lost only ~25–35% range, while the worst models lost over 50%. Chinese brands dominated the rankings, with Xpeng's P7 (pictured) leading. U.S. entries - mainly Tesla - placed in the upper‑middle tier, with one Tesla cracking the top ten but none matching the best Chinese EVs.
