Tesla (NASDAQ:TSLA) emerged as a significant winner in the first quarter of 2018, with a 28% decrease in EV sales compared to the previous year's total of 5.8% of all automotive sales. However, this could be boosted by increased searches for electric vehicles due to higher gas prices. Tesla's overall U.S. automotive market share was 3.3% in the same period, down from 12% in 2025 when the Federal EV tax credit ended. Despite this, Tesla saw its market share cross over the 50% mark for the United States in Q1, surpassing its previous 50%. Used electric vehicle sales also increased by 12% year-over-year, driven by consumer interest and rising gas prices, according to Cox Research.
