Tesla’s (NASDAQ:TSLA) Giga Shanghai, the company’s most efficient factory to date, is making strides in production efficiency and employee satisfaction, Teslarati reports.

Efficiency and Quality: With the efficiency of producing one vehicle every 40 seconds, Giga Shanghai is the largest in terms of output despite being relatively compact compared to other Tesla factories.

“The cars we produce here are not just the most efficient in production, but the highest quality,” Elon Musk, CEO of Tesla, praised the facility during a Q2 visit.
