Nine years after Elon Musk first unveiled it on a darkened stage, the Tesla Semi has finally crossed the line that separates promise from product.
On April 29, Tesla posted a single image on X: workers inside the Nevada factory, the first Semi off the high-volume production line. After years of delays, that photo carries more weight than any spec sheet.
What Tesla just announced
Tesla announced that the first Semi has rolled off its high-volume production line at the Sparks, Nevada factory, a 1.7 million square-foot facility built directly adjacent to Gigafactory Nevada, according to Electrek.
Volume production at that facility began in March. Tesla is targeting an annual capacity of 50,000 trucks, though analysts expect 5,000 to 15,000 deliveries in 2026 as the ramp builds gradually, Electrek noted.

Semi Program Director Dan Priestley put it plainly: “The economics are right. The product is ready. We have the factory standing up, but we have ample demand,” according to TESMAG.
What Telsa’s production Semi actually offers
Tesla is launching the Semi in two configurations. The Standard Range version delivers 325 miles and is priced at approximately $260,000. The Long Range version delivers 500 miles at $290,000. Both figures are based on a fully loaded 82,000-pound gross combination weight, according to Electric Cars Report.
The production version is 1,000 pounds lighter than earlier prototypes.
Combined with a federal weight exemption for electric vehicles, the Long Range Semi now achieves effective payload parity with conventional diesel Class 8 trucks, according to Electrek. It achieves 1.7 kWh per mile, a 15% efficiency improvement. The tri-motor drivetrain delivers 1,072 horsepower.
On charging, the Semi supports 1.2 MW speeds via Tesla’s Megacharger network. That recovers 60% of battery in approximately 30 minutes, timed to align with a driver’s mandatory rest break.
Tesla has 66 Megacharger locations mapped across 15 states. The batteries are designed to last one million miles, Electrek confirmed.

The economics that matter for fleets
Operating the Semi costs 50% less per mile on energy compared to diesel in California, Priestley said. DHL has confirmed an order beyond “just a handful” of Semis for 2026 delivery after testing in Livermore, logging 1.72 kWh per mile on a fully loaded 390-mile route, according to EV.
Demand signals are striking. In California’s Clean Truck and Bus Voucher program, the Tesla Semi accounted for 965 of 1,067 applications between January 2025 and February 2026. Daimler, PACCAR, and Volvo combined received fewer than 100, according to Electrek.
Key Tesla Semi figures at the start of volume production:
- Tesla Semi test fleet cumulative mileage: over 13.5 million miles, with the lead truck approaching 440,000 miles and 95% fleet uptime, according to Electrek
- Pilot Travel Centers partnership: four to eight Megacharger stations planned per hub in California, Georgia, Nevada, New Mexico, and Texas, with construction beginning in the first half of 2026, according to TESMAG
- ArcBest real-world efficiency test: 1.55 kWh per mile over 4,494 miles across three weeks, according to EV
- Uber Freight partnership: deploying Semi trucks through its Dedicated EV Fleet Accelerator Program, designed to lower upfront costs and route trucks through available charging infrastructure, EV confirmed
- Tesla 2026 capital expenditure guidance: above $25 billion, funding six new factories, AI infrastructure, Semi, Cybercab, and Optimus production ramps, according to Electrek
What this means for Tesla investors
The Semi has been a question mark on Tesla’s balance sheet for years. The company disclosed total 2026 capital expenditure guidance above $25 billion, with significant investment in the Semi factory, Cybercab production, and AI infrastructure, according to Electrek.
The Semi’s move to high-volume production changes that conversation. It has a price, a production address, a charging network in progress, and real fleet customers placing orders. The question for investors is no longer whether Tesla can build the Semi. It is how fast the Nevada factory ramps and whether the Megacharger network scales quickly enough to unlock long-haul routes beyond regional freight.
Tesla first unveiled the Semi in 2017. The production version that rolled off the line on April 29 is a meaningfully better truck. The market it is entering has been waiting long enough that it is no longer just watching.
