What Is the Weight of a Tesla Semi Without a Load?

Given the 53-foot trailer's empty weight and Elon Musk's claims that the Tesla Semi weighs a total of 81,000 pounds

 it appears that the Tesla Semi weighs about 27,000 pounds when hauled by a semi truck.

The first Tesla Semi EV is planned to have a 500-mile range on a fully loaded trailer, according to Musk

which means that the battery pack inside the vehicle will need to be absolutely enormous.

The Tesla Semi is now under 2000 pounds heavier than the average diesel truck if

 Tesla is expecting the payload capacity to be at least as much as what diesel vehicles will be able to carry.

The 82,000 pounds that Tesla semi trucks can transport over 6% of the world's mountains proves

that they have the range to transport cargo 500 miles.
