Two Tesla Semis were rolled out for the first time Wednesday.

Tesla (TSLA) unveiled the vehicles last year, but this was the first official cargo trip for the next-generation vehicles. 

CEO Elon Musk took to Instagram to show the trucks leaving the factory, saying that the vehicles were carrying battery packs from the Gigafactory to the Tesla factory in Fremont, California. 

The vehicles have a 500-mile range on a single charge and can carry a maximum load of 80,000 pounds. The trip is approximately 240 miles, so the vehicles should be able to make a round trip on a single charge.

The trucks are also supposed to be able to hit 65 mph on a 5% grade. 

During the truck's unveiling last year, Musk said that Tesla was working on a charging solution that would allow the vehicle to charge up to an equivalent of 400 miles in 30 minutes. 

The cabin of the vehicle allows full standing room with a seat situated in the center of the cabin with two touchscreen tablets on either side of the driver for navigations and blind spot monitoring.
