GM did not disclose the name or timing of the new GM EV but said it would be built on the same platform as the existing Chevrolet Bolt EV.
General Motors is expected to outline details of a new investment in the Orion Assembly Plant.
In January, the company announced that Cadillac will become its lead electric vehicle brand in an effort to make GM's electric cars profitable by 2023.
In November, GM announced plans to shut the four US factories and one in Canada. "This new Chevrolet electric vehicle is another positive step toward our commitment to an all-electric future", she said during the announcement Friday.
The new auto was originally expected to be built outside the U.S., but GM CEO Mary Barra said at an event announcing the new vehicle that terms of the new U.S./Mexico/Canada trade agreement encouraged the company to build it in the U.S.
The moves may help assuage Trump, who's attacked GM over its decisions announced in November to idle an OH plant and four other underutilized factories in the USA and Canada.
Production was to be outside U.S..
Moving production to a US manufacturing plant supports the rules of origin provisions in the proposed United States, Mexico and Canada Agreement.
GM has said it can place about 2,700 of the laid-off US workers at other factories, but it's unclear how many will uproot and take those positions. To date, 1,100 employees have been placed at other GM plants, with several hundred more in the process of being placed in new jobs.
According to the GM representative, the future of the Lordstown plant will be jointly decided by General Motors and the UAW.
Last year, GM said it would end production at five North American assembly plants and eliminate about 15,000 jobs, prompting outrage and a two-day visit by Barra to Capitol Hill to answer questions about the job cuts.
In addition to the Chevrolet Bolt EV, the Orion Assembly plant now builds the Chevrolet Sonic and the Cruise AV test vehicles.
Barra, speaking to reporters after an event at the plant in Orion Township, outside Detroit, with Michigan Governor Gretchen Whitmer announcing the investment, said GM is focused on ensuring that all of the hourly workers at Lordstown find new jobs at other plants.
The investment in Orion township is expected to create 400 new jobs.
The company says the plan will bring 400 new jobs to the MI plant. "Today's GM commitment of $300 million to build this electric vehicle, with our UAW members, is a good start on GM's investment toward keeping future manufacturing jobs here in America".
