U.S. President Joe Biden drives a Cadillac LYRIQ electric SUV during a visit to the Detroit Auto Show, to highlight electric vehicle manufacturing in America, in Detroit, Michigan, September 14, 2022.

The Biden administration announced new automobile emissions standards Wednesday that officials called the most ambitious plan ever to cut planet-warming emissions from passenger vehicles.

The new rules relax initial tailpipe limits proposed last year but eventually get close to the same strict standards set out by the Environmental Protection Agency.
