The Tesla Semi has set the goal of disrupting long haul transportation in the United States. The truck was announced in 2017, to be produced in 2019. Well, it’s 2022, and the truck still isn’t on the highway. But according to Tesla & Pepsi, that changes this year, with deliveries set to happen in December 2022. This brings up the question, does the Tesla Semi make any sense?
We’ll look at six major questions:
1. What is the battery capacity and weight?
2. How much range will it actually have?
3. How much does the Semi weigh, and how much power does it make?
4. What’s the charging rate?
5. How much will the Tesla Semi cost to opperate?
6. Will the Tesla Semi have better emissions than a diesel?
