Watch Tesla's new self-driving Semi truck prototype in action

This week, Tesla unveiled a video of its somewhat mysterious new prototype on a test track in Fremont, California offering the first official glimpse of its latest prototype truck actually driving. Earlier this month motorists spotted a Tesla Semi actually pulling a trailer and a “sneak peek” of its very stationary truck also surfaced online.

There’s little information available on the prototype beyond this video, but as noted by Electrek, the Semi was slated to be equipped with Tesla’s upcoming 4680 battery pack, so it’s possible we’re getting a preview of some future battery technology as well.

Though a video of a test drive isn’t much to go off, it is at least a visible sign of progress for bringing the Semi to market and fits in with Elon Musk’s internal calls last year for volume production of the truck.

It’s obviously too early to say whether any of those claims are founded, but if the first step is actually making a production line brand of electric self-driving semi-trucks, then Tesla is certainly making baby steps in the right direction.
