Tesla Semi runs at one-third the operating cost of a diesel truck
US fleet trials show the Tesla Semi costs about a third as much to run as a diesel truck, thanks to savings in energy and maintenance. Will it reach Spain with extra charges?

The Tesla Semi already operates at one-third the cost of a diesel
Fleet trials with real operators in the United States are producing a figure that shakes the foundations of road haulage: running Tesla's electric Semi truck costs roughly one-third of what a diesel truck costs. The company has sold several Semis to large independent fleets for long-distance pilot testing, and the first numbers point to a massive saving in energy per mile and greatly reduced maintenance.
Operating costs: the figure that changes everything
According to figures circulating in industry forums, the Tesla Semi's cost per mile is 66% lower than a diesel's. Not just because of cheaper electricity, but also because there are no oil changes, filters or brake wear (thanks to regenerative braking), plus lower general wear and tear. Logistics operators, green with envy, are already queuing up. And it's not just for urban routes: the trials cover long-distance journeys across the country, from plains to mountain passes.
The usual scepticism: infrastructure and charging
In the Spanish debate, the doubts are the usual ones. The power grid, at breaking point according to some, can barely cope with new housing, so electrifying the truck fleet sounds like a guaranteed blackout. On top of that, the argument about diesel trucks running 24/7 versus the electric truck's charging stops is still on the table. But the data from the American trials contradict that limitation: the Semi is already proving it has enough range for full working days, and the costs are so clear that the future of freight transport looks electric, no matter how hard people here try to find fault.
Taxes, levies and Iberian wariness
Of course, in Spain the bill doesn't end with energy costs: some claim the tax authorities and the power companies will make transport more expensive with new taxes and abusive charging tariffs. But if the base saving is 66%, even with regulated surcharges the margin remains huge. The question isn't whether it will arrive, but how long the diesel lobby and the bureaucracy will take to delay it.
Between the unanswerable evidence of the savings and the structural Iberian pessimism, the Tesla Semi moves forward. What is clear is that, on costs, diesel has already lost the game.
