Tesla delivered its first production Semi trucks on Thursday night to PepsiCo for use at its California facilities.

The all-electric tractor debuted as a concept in 2017 with an eye on entering production in 2019, but its development and later the coronavirus pandemic caused the date to be pushed off.

The truck arrives with many of the specifications originally promised, however, including a range of 500 miles per charge fully loaded.

Tesla CEO Elon Musk boasted at the event that it is more powerful than a diesel, and that it can accelerate to 60 mph in 5 seconds unladen and in 20 seconds with a full load, but did not reveal its exact specifications.
