Tesla's Model 3, which rolled off the production line six years ago, went from causing 'extreme stress and pain' to becoming the company's savior from bankruptcy. The production ramp-up was challenging due to production and logistics issues. However, the Model 3 emerged as the most popular EV in the world in 2020. In Q2, Tesla delivered 446,915 Model 3 and Y vehicles, accounting for the majority of its 466,140 total deliveries worldwide.
