GRUENHEIDE, Germany—Tesla fans flocked to the carmaker’s new factory near Berlin on Saturday, where Chief Executive Elon Musk staged a county-fair style festival to celebrate the site’s imminent opening.
Musk hopes in coming weeks to get the green light to start production at the site, which at its peak will produce 500,000 battery-electric vehicles (BEVs) a year—more than double Germany’s BEV production in 2020.
