Toyota's global production plan for June stands at about 850,000 vehicles, a cut of about 100,000 vehicles.

Toyota said there was "a possibility" that it could lower its full-year production plan of 9.7 million vehicles as it faces a continuing shortage of parts due to the COVID-19 lockdowns in China.

Mercedes, which did not disclose the location of Envision's new U.S. cell factory, also flipped the switch on a new battery assembly plant located on 270 acres near its vehicle factory.

Even the best supply chain planning is proving no match for a pandemic that virtually ground the auto industry to a halt a year ago and has plagued efforts to restore production.
