The nation's largest oil trade group, which includes Exxon Mobil and Chevron , will file a federal lawsuit on Thursday seeking to block the Biden administration's efforts to reduce planet-warming emissions from cars and light trucks and encourage electric vehicle manufacturing, the group said. The U.S. Environmental Protection Agency issued new tailpipe emission rules in March that will force the nation's automakers to produce and sell more electric vehicles to meet the new standards. The American Petroleum Institute (API) says the EPA has exceeded its congressional authority with a regulation that will eliminate most new gas cars and traditional hybrids from the U.S. market in less than a decade.
Exactly the two American car manufacturers are able to survive rather well so far with pretty much no sales abroad. They are still some of the largest in the world. That is besides the US being a large enough market for companies to seriously consider keeping their combustion engine technology around, if they believe it will sell. This obviously means they might lobby their home markets to keep them around as well. Stellantis is the most obvious company to maybe do that.
Bidens action turns 10% of global car sales electric(not counting other countries actions here) and forces GM and Ford to go electric.
