GM’s electric vehicle offensive continues as the company has announced plans to build EVs in Mexico.

The automaker didn’t say much about the upcoming models, but they’ll be built at the Ramos Arizpe Manufacturing Complex thanks to an investment of more than $1 billion.

While some of the funds will be used to create a new painting facility with “innovative technology,” the bulk of the money will be used to transform Ramos Arizpe into GM’s fifth EV plant in North America. Work is already underway and the first electric vehicles are slated to go into production in 2023. Before that happens, the facility will gear up to build batteries and electrical components for EVs.

GM is staying tight-lipped on what models will be built at the plant, but it has plans for an assortment of electric vehicles including crossovers for Buick, Cadillac and Chevrolet. The automaker will also offer “low roof entries” from Chevy and Cadillac.

The plant will presumably build one of those types of vehicles as Michigan’s Factory Zero will produce the Cruise Origin, GMC Hummer EVs and Chevrolet Silverado EV. The facility is also expected to build the Cadillac Celestiq and GMC Sierra EV, while GM’s Spring Hill plant in Tennessee will build the Lyriq.

While nothing is official, electric crossovers are the most likely candidate. In fact, previous reports have suggested Honda’s Ultium-based crossover will be built at the plant.

Regardless of what EVs will be made in Mexico, the Ramos Arizpe facility will continue to produce the Chevrolet Blazer and Equinox as well as engines and transmissions. The plant currently employs 5,600 people and exports products to more than 40 countries.
