Tesla hit a key milestone in the second quarter, managing to hit a 5,000-per-week production target for its important Model 3 electric vehicle. Remarkably, about 20 percent of the 5,031 Model 3 vehicles made in the past seven days were produced on the company’s GA4, a hastily built general assembly line housed under a massive tent at its Fremont, California factory.

News that Tesla had hit the 5,000-per-week target came out Sunday as the last Model 3 rolled off the assembly line and employees celebrated. Tesla CEO Elon Musk tweeted later that day the company had produced 7,000 vehicles in a week, a figure that includes Model S and X vehicles as well.
