Elon Musk said Tesla will deliver its first 'super fun to drive' semi trucks to Pepsi in December this year

• Tesla has begun production of its all-electric Semi, Elon Musk said.

• Musk said on Twitter that PepsiCo will receive its first deliveries on December 1.

• Semi production has been postponed several times since the truck was unveiled by Tesla in 2017.

Tesla has started production of its long-awaited, all-electric Semi tractor-trailer, and will deliver the first vehicles by December this year, CEO Elon Musk said in a tweet.

"Excited to announce start of production of Tesla Semi Truck with deliveries to @Pepsi on Dec 1st!," Musk posted on Twitter, on Thursday, alongside a mock-up of the all-electric truck.

"500 mile range & super fun to drive," Musk added in the thread.

The Semi Truck is Tesla's range of all-electric, class-8 cargo trucks. The vehicles will be able to travel between 300 and 500 miles on a single charge, depending on the model.

Pepsi has ordered 100 of what it refers to as Semi Tractors, 15 of which it expects to be deployed by the end of 2022, per its website. Walmart Canada is among other high-profile retailers to have also ordered the trucks.
