Core Viewpoint - The article emphasizes the importance of the drag coefficient in electric vehicles, highlighting it as a critical factor affecting the range of electric cars [1] Group 1: Importance of Drag Coefficient - The drag coefficient is often overlooked but is crucial for electric vehicle range, with energy consumption at 120 km/h reaching up to 70% due to drag [1] - A slight difference in drag coefficient can lead to a significant variation in range, potentially affecting the distance by several dozen kilometers with the same battery capacity [1] Group 2: Recent Developments - The Zhijie R7 has recently achieved a key certification in a professional wind tunnel, with its pure electric Ultra version recording a drag coefficient of only 0.217 under specific testing conditions (120 km/h at 23°C) [1]
