Video shows Tesla Semi’s acceleration — and gives a listen at it’s whirring electric motor

The video above, unearthed by Electrek.co, shows a Tesla Semi in action in an undetermined location. More than just providing a glimpse at the all-electric rig’s acceleration ability, the video also provides good audio of what the rig sounds like. It’s not exactly the roar of a diesel-powered Caterpillar, but it’s not a meow, either.
