Tesla Semi meets $6 diesel

Tesla Semi meets $6 diesel

Tesla's long-delayed electric Semi is finally going into mass production, with the company opening its first factory Thursday in Nevada.

Why it matters: The economics of electric 18-wheelers have long been challenging, but record diesel prices are suddenly making the equation a lot more compelling.

Driving the news: Tesla launched production of the Semi Thursday, saying it can build up to 50,000 electric trucks per year.

  • The long-range version can travel 500 miles on a charge while fully loaded, using new battery technology Tesla developed in-house.
  • And it can regain up to 60% of its range in 30 minutes, Tesla says.

    • Friction point: Giant batteries in electric big rigs add weight and cost, sacrificing cargo capacity and range compared to diesel cabs.

  • EVs cost a lot more upfront, and charging infrastructure is still sparse along many freight corridors.
  • But for shippers, it's all about total cost of ownership.

    • Follow the money: The cost of diesel has spiked to roughly 80 cents per mile in recent months, while electricity costs between 20 cents and 30 cents per mile, according to a chart Tesla shared at the launch event for Semi.

  • Tesla claims its Semi fleet has had over 98% uptime so far in 2026 and says the truck "requires almost no maintenance."

    • What they're saying: Forum Mobility, which leases out electric trucks to freight operators, says 25 carriers have already reserved capacity for more than 330 Tesla Semis at one Southern California depot.

  • "That truck has changed everything," CEO Matt LeDucq tells Axios.
  • The operating cost on a Tesla Semi is up to 30% cheaper, and the duty cycle is "very capable" despite the heavy battery, he said.
  • "This becomes a no brainer for the truck driver."

    • The intrigue: Forum is trying to turn electric trucking into a service rather than a giant capital investment.

  • The company leases out electric trucks for as little as $1,500 a month while providing access to shared charging depots, tackling two of the biggest obstacles facing smaller trucking fleets.

    • State of play: Tesla has deployed about 200 Semis since 2022, primarily through limited customer programs, but orders are piling up as the company begins volume production.

  • PepsiCo was an early adopter, with at least 50 already in operation in California.
  • This week, a coalition of major shippers ordered 2,500. Other noteworthy Tesla Semi customers include DHL, Einride, Walmart, IMC Logistics and ArcBest.

    • The bottom line: At $3 or $4 diesel, electric trucks can be a tough sell. Above $6, fleet operators have a powerful reason to sharpen their pencils.
