Palo Alto-based Tesla Motors Inc. has quietly leased a 431,000-square-foot industrial facility in the San Joaquin County city of Lathrop that it is already building out, according to city and county officials. The news, which was first reported by the Manteca Bulletin this morning, comes as fast-growing Tesla (NASD: TSLA) ramps up with plans to sell 35,000 Model S sedans this year, according to the Wall Street Journal.
