又来！美国汽车燃效标准“开倒车”

Group 1 - The Trump administration has announced a rollback of fuel economy standards for new vehicles in the U.S., reducing the average requirement for 2031 models to 34.5 miles per gallon, significantly lower than the current standard of 50.4 miles per gallon [2][4] - The new standards will require only a 0.5% annual increase in fuel efficiency from 2023 to 2026, and a further reduction to 0.25% thereafter, contrasting with the previous administration's requirement of a 2% annual increase [4][10] - The average price of new cars in the U.S. has reached approximately $49,105, with inflation and high production costs being major concerns for consumers [4][5] Group 2 - Major automakers, including General Motors and Ford, have expressed support for the new fuel economy standards, stating that they align better with market realities and will allow for investment in more affordable vehicles [6] - Critics, including environmentalists and some state governments, argue that the rollback will have detrimental effects on air quality and climate change, potentially increasing fuel costs for consumers [6][7] - Analysts have raised concerns that the administration's claims regarding the impact of fuel economy standards on car prices may overlook other significant factors, such as supply chain issues and consumer preferences for larger vehicles [7][8] Group 3 - The Trump administration's policies have systematically reversed the electric vehicle support framework established under the Biden administration, including withdrawing from the Paris Agreement and halting funding for electric vehicle infrastructure [8][9] - The recent "Big and Beautiful" legislation has eliminated penalties for automakers not meeting fuel economy standards, further reducing the incentive for electric vehicle production and impacting the carbon credit market [9] - The ongoing public comment period for the new fuel economy regulations indicates that the final decision will be a contentious issue within the automotive industry, with potential implications for vehicle production strategies [10]
