(Reuters) - Chrysler parent Stellantis ( STLA ) is expanding its factory complex in northern Mexico to build Ram 1500 pickup trucks, the Wall Street Journal reported on Tuesday.

Stellantis ( STLA ) has been building additional factory space next to its existing plant in Saltillo, Mexico, the report said, citing people familiar with the matter.

Two roughly half-kilometer-long buildings have been constructed in the past several months, according to satellite images reviewed by the newspaper.

However, the French-Italian automaker said that the Ram trucks would continue to be made at its Sterling Heights assembly plant, in the north of Detroit, and that "no other announcements have been made about production of the Ram 1500," according to the report.

It is not clear if the planned factory space in Saltillo would be used to make battery- or gas-powered versions of Ram trucks, the report said.

Stellantis ( STLA ) did not immediately respond to a Reuters request for comment.

In August, Stellantis ( STLA ) announced plans to lay off as many as 2,450 factory workers from its Warren Truck assembly plant outside of Detroit after ending production of the Ram 1500 Classic truck.
