Tesla CEO Elon Musk kicked off deliveries of the company's first few production Semi trucks on Thursday, speaking on stage at the company's factory in Sparks, Nevada, with Dan Priestly, the company's senior manager for Semi truck engineering.

As CNBC previously reported, Tesla set up lines and started production of the Semi outside of Reno this year at the site where it primarily makes the battery cells, drive units, and battery packs that power its cars.

He later thanked and the handed the mic to representatives from PepsiCo Frito Lay, which is Tesla's first customer to receive and use production Semi trucks.

While the Tesla Semi was in development, other fully electric heavy-duty trucks launched into the market.

Volvo-owned Renault Trucks and Daimler haveproduced and delivered electric heavy-duty trucks to customers before Tesla Even beleaguered Nikola -- whose founder was ousted and convicted of fraud in recent months -- started production of a battery electric truck in March.

The Tesla Semi event may provide relief to fans worried about his commitment to and focus on the electric vehicle business.

The same can be said of other electric, heavy-duty trucks that displace diesel trucks.
