Trump's reelection has put a number of California clean air initiatives at risk, including a rule that would require an increasing number of cars sold to be zero-emission or hybrid vehicles.
(2) The 2014 i3 REx is classified by EPA as a series plug-in hybrid, while for CARB is a range-extended battery-electric vehicle (BEVx). The i3 REx is the most fuel economic EPA-certified current year vehicle with a gasoline engine with a combined gasoline/electricity rating of 88 mpg-e, but its total range is limited to 150 mi (240 km).

Section 202(a)(1) of the Clean Air Act requires the Administrator of the EPA to establish standards "applicable to the emission of any air pollutant from…new motor vehicles or new motor vehicle engines, which in [her] judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare" (emphasis added).
