销量腰斩，车企停产，美国电动车进入寒冬

Core Viewpoint - The cancellation of federal electric vehicle (EV) tax credits in the U.S. has led to a significant decline in EV sales, marking a downturn for the industry that heavily relied on government support [5][7][11]. Group 1: Impact of Policy Changes - The "One Big Beautiful Bill" enacted on October 1 ended the federal EV tax credit, which previously provided $7,500 for new electric vehicles and $4,000 for used ones, leading to a sharp decline in consumer demand [7][8]. - Following the end of the tax credit, EV sales in October plummeted by 30.3% year-over-year and 49% month-over-month, with only 91,000 units sold, resulting in a market penetration rate of 5.8% [8]. - November saw an even steeper decline, with sales dropping by 40% year-over-year to 76,000 units, further decreasing the penetration rate to 5.1% [8]. Group 2: Market Reactions and Adjustments - Traditional automakers are scaling back their electric vehicle ambitions, shifting focus to hybrid and traditional fuel vehicles due to the lack of consumer demand and profitability in the EV sector [19][20]. - Ford announced a $19.5 billion asset write-down, with $8.5 billion attributed to its EV division, and is halting production of its F-150 Lightning electric truck to focus on hybrid models [21][22]. - General Motors is also adjusting its electric vehicle strategy, postponing production timelines and reducing its electric vehicle output targets due to the changing regulatory environment [19][20]. Group 3: Comparison with China - The U.S. EV market is experiencing a stark contrast to China, where EV sales reached 11 million units last year, accounting for 40% growth, while the U.S. market saw only a 7% increase [12]. - The disparity in EV adoption is attributed to the U.S. government's inconsistent policies, which have created uncertainty for manufacturers and consumers alike [12][19]. - American consumers face significant barriers to EV adoption, including higher prices, lack of charging infrastructure, and concerns over vehicle depreciation and insurance costs [14][16].
