Core Viewpoint - Smart Automobile has suspended its charging cooperation with several operators, including Star Charge, Teld, and Xiaojun Charging, leading to the removal of their charging stations from the Smart Automobile app [1] Group 1: Charging Cooperation - Smart Automobile's collaboration with multiple charging operators has been interrupted, resulting in the removal of these operators' station resources from the Smart Automobile app's charging map [1] - Previously, Smart Automobile allowed users to redeem points for charging fees, with self-operated stations offering up to 100% discount and other stations up to 80% [1] - The interruption is speculated to be due to financial pressures, and there are no plans for renewal of contracts with these operators [1] Group 2: Market Performance - Smart Automobile is facing declining sales pressure in the Chinese market, with projected sales of 33,280 units in 2024, representing a year-on-year decline of 21.31% [1] - For 2025, the projected sales are 30,799 units, indicating a further year-on-year decline of 7.45% [1]

Core Viewpoint - Smart Automobile has suspended its charging cooperation with several operators, including Star Charge, Teld, and Xiaojun Charging, leading to the removal of their charging stations from the Smart Automobile app [1][2]. Group 1: Charging Cooperation - Smart Automobile previously collaborated with multiple charging operators, allowing car owners to use points to offset charging costs, with self-operated stations offering up to 100% discount and other stations up to 80% [1][2]. - The charging stations from Star Charge, Teld, and Xiaojun Charging are no longer visible on the Smart Automobile app, confirming the disruption of cooperation [1][2]. Group 2: Reasons for Suspension - Insiders suggest that the suspension of cooperation may be due to financial pressures, and there are no plans for future contracts with these operators [1][2]. Group 3: Sales Performance - Smart Automobile is facing declining sales in the Chinese market, with projected sales of 33,280 units in 2024, representing a year-on-year decrease of 21.31%, and 30,799 units in 2025, reflecting a 7.45% decline [1][2].

Core Viewpoint - The pursuit of low drag coefficients (Cd) in the automotive industry is prevalent, but a lower Cd does not necessarily equate to lower overall drag due to the influence of other variables such as frontal area, air density, and speed [4][9]. Summary by Sections What is Drag? - Drag is the resistance experienced by an object moving through air, consisting of impact drag, friction drag, and shape drag [2][3]. Drag Coefficient (Cd) - The drag coefficient (Cd) is a dimensionless number that quantifies the drag force experienced by an object in a fluid, reflecting the energy loss efficiency as fluid flows around it [4]. Frontal Area (A) - The frontal area refers to the projected area of an object facing the wind, which is a controllable parameter that directly affects drag [6]. Air Velocity (v) - Drag is proportional to the square of the vehicle's speed, meaning that as speed doubles, drag increases exponentially, highlighting the significant impact of speed on energy consumption [8]. Air Density (ρ) - Air density varies with altitude, temperature, and humidity, affecting the actual drag experienced by a vehicle, even if the Cd and speed remain constant [8]. Misconceptions about Low Cd - A lower Cd does not guarantee lower overall drag, as other factors like frontal area and speed play crucial roles. For instance, a Boeing 787 has a much lower Cd than a Mercedes AMG GT, yet its total drag can be higher due to its larger frontal area [9].

撰 文 / 刘宝华 设 计 / 琚 佳 2024年的汽车流通业，卷不忍睹。 全年退网4S店约4,000家，广汇摘牌退市，宝马全球首家5S店北京星德宝关店停业，华南首家奥迪 5S店广州京溪奥迪改卖蔚来，北京华阳奥通和郑州中升汇迪两家顶流奥迪经销商转投问界，长沙最 大的奔驰4S店变身问界旗舰店。 中国汽车流通协会发布的调查报告显示，2024年汽车经销商亏损比例41.7%，84.4%的经销商有不 同程度的价格倒挂，60.4%的经销商价格倒挂幅度超过15%。 经销商如此艰难，直营可能更不乐观。几年前选择了直营模式的新品牌，如今不少开始转头和经销 商合作。阿维塔从直营转向经销商为主，腾势和方程豹从直营转向"直营+经销商"，小鹏几年前就 做了相同调整。其他不少新能源品牌虽然没有官宣，但也在低调地增加经销商模式，不再单纯依靠 直营。 在汽车行业百年未有之大变局中，汽车流通也迎来革旧鼎新大潮，传统车企与新势力都在寻找更适 合自己的渠道模式，4S店、经销商模式一统天下的时代就此作别。 3月中旬，smart品牌面向广东深圳、佛山、中山、珠海、湖北武汉、襄阳、黄冈、江苏镇江、安徽 阜阳、四川成都、宜宾、乐山、湖南常德、株洲、江西赣 ...
