January 26, 2021: President Joe Biden plans to replace the government’s fleet of cars and trucks with electric vehicles assembled in the U.S.; he said on Monday when signing a new “Buy American” executive order.

A few all-electric vehicles being assembled in the U.S. Tesla, General Motors, and Nissan Motor produce EVs domestically. In contrast, Ford Motor and others have announced plans to do so. However, buying and replacing cars with American EVs will be expensive and takes time.

“The current offerings are pretty slim, but the industry’s about to unleash an avalanche of the new product, and a lot of it built in North America,” Kristin Dziczek, vice president of industry, labor, and economics at the Center for Automotive Research.

It’s unclear whether Biden’s plan includes plug-in hybrid electric vehicles, which use a combination of EV motors and traditional internal combustion engines. When discussing the plans, he referred to the new fleet of electric vehicles “that are net-zero emissions.”

It is unestablished if Biden wants to plug-in hybrid electric vehicles, which use EV motors and traditional combustion engines.

Biden said the fleet changeover would assist his administration’s plan to create 1 million new jobs in the U.S. auto industry. However, Biden did not specify a particular period to switch the vehicles.

Biden also announced plans for stricter use of American-made parts in government-purchased vehicles, which will make it even more difficult to switch over the fleet.

“The executive action I’m signing today will not only require the companies make more of their components in America but that the value of those components is contributing to our economy, measured by things like several American jobs created and supported.” Said Biden.

GM said it is “encouraged by Biden’s commitment to supporting American manufacturing and looks forward to reviewing the details of the order.”

Last year, Ford launched a “Built for America” ad campaign, said it “believes that investing in America, its people, goods and services, must be a national mission.”

Tesla did not immediately respond to a request for comment.
