California sold 404,818 new zero-emission vehicles in 2025 across the four quarterly releases of the California Energy Commission, with the ZEV share of new car sales running from 18.9% to 29.1% by quarter, about 23% for the year on AutoNergy's sum. Nationally, EVs were 7.8% of 2025 sales (Cox Automotive). Texas, the second-largest state market by volume, has a far lower EV share. The geographic divide in US EV adoption is as wide as the divide between European countries.
Why California Leads
Three structural factors. First, the Zero Emission Vehicle (ZEV) program, which forces automakers to deliver minimum EV percentages or face credit penalties, and California leads a group of states that adopted its rules. Second, state and local incentives, including income-qualified programmes, layered on top of what were federal credits. Third, charging infrastructure: the CEC counts over 200,000 public and shared private charging stations in the state, plus around 800,000 home chargers.
Why Texas Lags
Texas has no state-level EV purchase incentives, charges an extra annual EV registration fee ($200), and has a sprawling rural geography that makes home charging easy for many drivers but long-distance EV touring less attractive. Pickup trucks are a much bigger part of the Texas market than of California's, and the BEV pickup market remains thin.
The Federal Variable
The federal $7,500 EV tax credit ended on 30 September 2025, and in June 2025 Congress voted to revoke the federal waiver for California's newest ZEV rules, which California is contesting in court. The fourth quarter showed the effect: the CEC reports California's ZEV share fell to 18.9% while the national share fell from 10.5% in the third quarter to 5.8%. California held up far better than the country as a whole, so the geographic divergence widened.
