General Motors has announced it will invest $300 million in its Orion Township plant in Michigan, to produce a new Chevrolet electric vehicle, adding 400 new jobs to the facility.

The new Chevrolet EV will be “designed and engineered off an advanced version of the current award-winning Bolt EV architecture,” GM says. It provided no other information on the mystery EV, only saying that “additional product information and timing for the new Chevrolet EV will be released closer to production.”

GM selected Orion Assembly to build the new Chevrolet EV as it already builds the Bolt EV with which it will share a platform. The automaker also said that a US manufacturing plant “supports the rules of origin provisions in the proposed United States, Mexico and Canada Agreement.”

In addition to the Bolt EV, Orion Assembly also manufactures the Chevrolet Sonic and the Cruise AV autonomous test vehicles. It currently employs around 880 hourly and 130 salaried workers.

This announcement is part of a larger commitment from GM to invest $1.8 billion in its American manufacturing operations and add a total of 700 new jobs across six states. The automaker says the $1.8 billion figure includes investments at its Spring Hill plant in Tennessee as well as the Lansing Delta Township plant and the Romulus plant – both in Michigan, with more investments to be announced at a later date.

“We are excited to bring these jobs and this investment to the U.S.,” GM CEO Mary Barra said in a prepared statement. “This new Chevrolet EV is another positive step toward our commitment to an all-electric future. GM will continue to invest in our U.S. operations where we see opportunities for growth.”
