As you’ll hear in the video, there’s no mistaking the sound — or lack thereof — of the electric powertrain. Take a closer look and you’ll see that the truck has a California license plate and has been registered with the U.S. Department of Transportation. Also, this truck has side view mirrors; the Semis revealed last month by Tesla CEO Elon Musk did not.
It may be just coincidental that the truck rolled past UPS. The shipping giant announced plans last month to buy 125 Tesla Semis, the largest public pre-order yet. Tesla plans to have the truck in production by 2019.
