PALO ALTO (CBS SF)— Electric car maker Tesla Motors is expanding in California. The Bay Area company has leased a 430,000 square-foot building in Lathrop, a community on Interstate 5 near Manteca. Tesla has not said what it plans to do with the space.

The building used to serve as a DaimlerChrysler parts distribution center, although it has sat vacant for several years.

Tesla currently has manufacturing space in the old NUMMI plant in Fremont. It also plans to put up a massive battery factory, though California does not appear to be in the running for that.

The Sacramento Bee reports that the Lathrop facility is too small for the battery plant.
