The first deliveries of the all-electric semi truck will take place in December, according to Musk.

An all-electric Class 8 truck prototype was introduced by the company at a splashy event in Hawthorne, California, on the grounds of the company's design studio.

The reveal came more than a year after the launch of the trucks program at the company. Just a few months after his position was changed from president of the company's automotive business to a more narrow role, Guillen left.

The semi truck was supposed to be produced in December. The program was delayed many times.

Due to supply chain challenges and the limited availability of battery cells, the Semi truck program was pushed back from 2020 to 2022, according to the company. The company had finished engineering work on the Semi and was on track to deliver it in January 2021. The availability of battery cells could limit the company's ability to make the Semi.

The company has been able to get reservations from a number of high-profile companies despite the delays. The first customer to receive the vehicles will bePepsi.

December 1 is when Musk expects deliveries to be made toPepsi.
