PepsiCo ordered 100 trucks in 2017.
Musk has not revealed the price and capacity of its all-electric truck.
The battery-powered truck would reduce highway emissions.
Musk said it would outperform diesel models.
Tesla started developing this idea five years ago.
Musk said Semi will be used to ship parts to Tesla’s plant in California.
Tesla might produce 100 semis this year.
It aims to produce 50,000 trucks in 2024.
