The cost of filling up a Tesla Semi depends on various factors, including the current price of power and the distance you expect to travel.
The typical cost to completely charge a Tesla Semi, which has a range of 500 miles, is approximately $200.
Traditional diesel fuel, which may cost several thousand dollars to fill a semi-truck, is substantially more expensive than this.
Furthermore, fueling a Tesla Semi using a Tesla Supercharger is substantially less expensive than charging at a conventional electric charging station.
In addition, the Tesla Semi is fitted with regenerative braking, which recharges the battery and reduces the cost of ownership even further.
