According to Electrek, multiple Tesla employees and other workers inside Tesla's Giga Texas posted videos on Snapchat. Electrek combined the footage into a 4-minute YouTube video to showcase the ramp-up at the factory in Austin.
The YouTube video includes footage of the production lines, which we haven't really seen in the past. However, we do know that Tesla is running the lines, since it already produced several Model Y electric crossovers at the site.
Tesla will begin delivering Model Y's built at the Texas plant in the coming months. According to Tesla, those vehicles will have the new structural battery pack and 4680 cells. The company recently shared that the goal is to begin Model Y deliveries before the end of Q1 2022.
