The impressive economy of the Tesla Semi compared to a diesel truck

Since Elon Musk presented the Tesla Semi at the end of 2017, it was the subject of a real buzz. For now, the electric truck is still months away from reaching buyers, who are now expecting a 2023 debut. to make diesel-powered trucks obsolete in terms of performance and economy.

On this last point, some data has come to light which affirms that, in the sole comparison of the cost of fuel and energy, a Tesla Semi can be over 83% cheaper than a diesel truck. The figure is brutal and, if true, it will be a game-changer for the transport sector. But is this really the case?

Recently, a Twitter user called Alex Gayer shared a cost comparison between the fuel consumption of a conventional diesel-powered truck and a Tesla Semi. According to his calculations, to complete a 200-mile trip, the electric truck would only need a fraction of the budget of its counterpart.

Specifically, the internal combustion engine vehicle would need about 34 gallons of diesel nearly 127 liters to cover the trip. On average, it can travel about 9.5 kilometers on a gallon. And given that the price per gallon of diesel on the highways is currently $4.99, according to the US Energy Information Administration, the calculation would result in a cost of 1.5 million euros. $169.76 fuel to go the 200 miles..

In analyzing the case of the Tesla Semi, Mr. Gayer took as a reference the consumption announced by the manufacturer, namely “less than 2 kWh per kilometer”, and rounded it, for practical reasons, to 2 kWh. Thus, to cover a 200 mile trip, 400 kWh would need to be used, which, multiplied by a price of 7 cents per kilowatt hour, would require 400 kWh. would only cost $28 to cover the distance..
