Semi is the safest, most comfortable truck ever. Four independent motors provide maximum power and acceleration and require the lowest energy cost per mile.

and accounting for the greater efficiency of electric motors, as well as regenerative braking, the envelope engineers estimated that an electric semi would require a 1,200 kWh battery pack to achieve a range of 600 miles. At a cost of $100/kWh, which Tesla hopes to reach soon, that would be a $120,000 battery. According to a 2016 article from AskTheTrucker, the cost of a new diesel-powered tractor starts around $113,000, and annual fuel costs are “easily more than $70,000.”
