Greetings again from the Tesla Truck Team! We recently wrapped up a great year, we achieved record production & deliveries, GAAP profitability, completed Gigafactory Shanghai ahead of schedule, launched new solar and energy products, and confirmed that we are on track to produce limited volumes of the Tesla Semi in the second half of 2020.

Over the last few months continued testing the trucks in real-world conditions. We also spent time at a proving ground to evaluate truck's resilience over rougher road conditions. Using instruments mounted on the vehicle, we collected road input data to ensure the trucks can handle severely degraded roads. At our own Fremont test facility, we subjected the trucks to a number of high energy discreet events such as curbs strikes, potholes, and other harsh inputs to confirm the truck is capable of Harding common hazards. Our test vehicles have held up great thus far and continue to impress. In addition to real-world tests, we also successfully completed several important engineering development checkpoints. As the truck's design continues to mature, those improvements are being rolled into our plans for building more production-representative vehicles, which we will have more details on next year. In the short term, the team is gearing up for several weeks of winter testing to validate the truck's performance in cold weather and low traction conditions. We are excited to share insights from the winter with you, as we will be able to highlight the major advantages of electric traction and motor control, which no diesel powertrain can match.

Over the last two years, we have also been actively engaged with CharIN, and industry working-group representing OEMs, customers, and charging equipment suppliers. CharIN has been working on to define a standard for charging heavy-duty electric vehicles, and we have shared our expertise in the hope to be able to share the good outcome of those conversations with you in the coming months — stay tuned.

Thanks again for your support
