The Semi was first announced in 2017, and was originally supposed to enter production two years later in 2019. The program was delayed and pushed back several times over the years, mainly due to battery supply constraints as Tesla ramped production of the Model 3, and subsequently the Model Y.
The Semi will be able to travel 500 miles (804km) on a full charge, when fully loaded at 82,000lbs Gross Combination Weight. It will also be able to reach 60mph in just 20 seconds, compared to as much as 60 seconds for a traditional diesel semi.
