By the time Tesla’s Semi rolls into full production this year, it will have taken one of the longest victory laps in modern automotive history. Nearly ten years after Elon Musk first pulled the wraps off the futuristic electric big rig in 2017, Tesla now says the Semi is finally ready for true mass production and customer deliveries. And, for the first time, we have a clear picture of what the production-spec truck actually is.

The short version? It’s big, it’s powerful, it’s very fast to charge—and it’s probably not going to be cheap.

Two Trucks, One Mission: Kill Diesel

Tesla will sell the Semi in two flavors: Standard Range and Long Range. Both are rated for a gross combined vehicle weight of 37.2 tons (about 82,000 pounds), meaning they’re designed to haul a full-size trailer without excuses. Underneath, both versions use a tri-motor drivetrain producing 800 kW, or 1072 horsepower—a figure that would have sounded absurd in trucking a decade ago, but now sits at the heart of Tesla’s diesel-disrupting pitch.

The Standard Range Semi is rated for 523 km (325 miles) on a full load. The tractor itself weighs about 9 tons, leaving room for a 28-ton payload, and Tesla claims an energy consumption of 1.7 kWh per mile—an impressively low number for something that can tow a small apartment building down the highway.

Step up to the Long Range Semi and the range jumps to 805 km (500 miles). Tesla still won’t officially say how big the battery is, but at the same consumption rate, it works out to roughly 900 kWh—which is about 13 times the capacity of a Model Y. The tradeoff is weight: the tractor grows to 10.5 tons, cutting payload to 26.7 tons. For long-haul operators, though, that extra range will likely be worth the hit.

Megawatts, Not Kilowatts

The Semi’s other headline feature is charging. Both versions use the Megawatt Charging System (MCS 3.2), allowing peak charging power of up to 1.2 megawatts. That’s not a typo. Tesla says the battery can go from empty to 60 percent in just 30 minutes, roughly the length of a mandated driver break. In theory, that makes the Semi viable for real-world freight cycles, not just short shuttle routes.

Tesla has also built in an electric power take-off (ePTO) system delivering up to 25 kW, letting the truck run refrigerated trailers, hydraulic systems, or other auxiliary equipment without firing up a diesel generator. It’s a small detail that matters a lot in commercial use.

The Slow Road to Production

This isn’t Tesla’s first time building Semis. Limited production started back in late 2022, with early trucks going to PepsiCo, followed by smaller fleets at Walmart and DHL Supply Chain. Those pilot programs were essentially rolling test beds, feeding data back to Tesla while the company ironed out the last production wrinkles.

Now Tesla says it’s ready to scale up, turning what was once a flashy prototype into an actual product you can order.

The Price Nobody Wants to Talk About

And that brings us to the elephant in the loading dock: price.

Tesla is staying silent, but history gives us some clues. Back in 2017, Musk promised a $150,000 price for a roughly 300-mile Semi and $180,000 for the 500-mile version. Those numbers look downright quaint in 2026, given inflation, battery costs, and the simple fact that the Long Range Semi now packs a battery larger than most houses.

One indirect hint came from Ryder, which quietly cut its Semi order from 42 trucks to 18 while keeping the total budget at $7.5 million. Do the math and you’re looking at something north of $400,000 per truck—a far cry from the original promise.

Even with sticker shock, the Tesla Semi is shaping up to be one of the most important EVs on the road. With over 1000 horsepower, megawatt-level charging, and real-world range numbers that make long-haul electrification plausible, it’s no longer just a Silicon Valley science project.

After almost a decade of waiting, Tesla’s electric big rig is finally ready to do what it was always meant to do: take on diesel where it actually counts—on the open road, hauling real cargo, for real customers.
