Tesla has finally provided an exclusive first look inside its long-awaited Semi factory in Sparks, Nevada. Located appropriately on Electric Avenue, the facility represents the final chapter in a journey that began with Elon Musk’s Master Plan Part Deux in 2016.
Journalist Ashlee Vance and the Core Memory crew were granted rare access to the factory in March 2026, guided by Dan Priestley, the head of Tesla’s Semi program. The tour reveals a facility that is currently in its final phase of preparation for mass production. After breaking ground less than two years ago, the team spent a year erecting steel and running utilities before moving in the heavy equipment that is now being powered on for the start of production.
Tesla is utilizing a highly vertical manufacturing layout to maximize efficiency. The factory features massive overhead carriers—some of the largest of their kind in the world—that move sub-assemblies through the air. This loop allows the heavy components, which can weigh well north of 10,000 lbs, to be lowered to the perfect height for operators at different stations.
A key highlight of the production line is the “battery marriage” station. Unlike the flat “pancake” battery packs found in Tesla’s passenger cars, the Semi uses three cube-shaped packs that nestle tightly into the frame. Priestley noted that these packs utilize the same cells found in the Cybertruck, providing a massive amount of energy storage in a compact footprint.
The Semi is being produced in two configurations:
While the truck is a massive business tool, it is designed to drive with the precision of a passenger car. The electric motors provide effortless torque even when hauling a 40,000 lb payload, and regenerative braking eliminates the traditional risks of gear-shifting or brake failure on steep grades.
Operating on a dollar-per-mile basis that is substantially cheaper than diesel, the Semi aims to disrupt an industry where trucks make up only 1% of vehicles but account for nearly 18% of all fuel consumed. With less maintenance and higher reliability, Tesla is betting that even cautious fleet operators will be convinced once they stress-test the vehicles in their own operations.
Every purchase includes access to a dedicated supercharging network Tesla is currently building specifically for these heavy-duty haulers.
The facility also features a giant “light tunnel” for final quality checks, a station so impressive Vance joked that employees might want to get married there. For Tesla, this factory is the culmination of nearly a decade of development, turning the ambitious 2017 prototype into a mass-manufactured reality.
