In a Nutshell

Tesla's Semi factory in Sparks, Nevada, broke ground less than two years ago and is now in final prep for mass production of the long-range electric truck, featuring on-site stamping, injection molding, overhead conveyance for massive assemblies, and cube-shaped battery packs using Cybertruck cells. The Semi offers 325-mile standard or 500-mile long-range variants, drives like Tesla cars with instant torque, regenerative braking, and 10 cameras for superior control, slashing dollar-per-mile costs versus diesel while cutting emissions. Truckers praise lower maintenance and reliability after demos, despite some caution on charging, as Tesla builds a dedicated supercharging network.

Tesla Semi is the long-awaited cargo-hauling vehicle from Tesla, marking a new chapter for the company and automotive industry. The Tesla Semi factory is located in Sparks, Nevada on Electric Avenue. Exclusive first look inside the factory.

Walking tour of the factory. Broke ground less than 2 years ago. Spent 6 months putting up steel and walls, 6 months preparing inside with utilities, then bringing in equipment. Now in last phase: turning on equipment and prepping for start of production. Arrived in early March 2026. Tesla gearing up for mass production.

Factory Setup and Lessons Learned

Took lessons from other factories: layout, vertical integration. Stamping on site. Using injection molding from nearby Gigafactory building.

Guide's Background

Started as intern in battery engineering. At Gigafactory Nevada since 2014. JB (co-founder, now board member) questioned shipping parts between Fremont, California and Reno, Nevada on diesel trucks. Realized business case due to environmental impact. Diesel trucks are 1% of vehicles on road but 16-18% of fuel consumed. Semi truck substantially cheaper on dollar per mile basis running electric than diesel.

Unveiled initial design in 2017. Tesla mentioned Semi aspirations in 2016 Master Plan Part Deux. Revealed prototype in 2017, planned production by end of 2019. Delivered early versions to select customers in 2022. Now final design entering manufacturing.

Complete cab ready to be put on overhead conveyance. Larger assemblies moved above ground floor. Goes to coatings area for corrosion protection and visual appeal. Carriers above handle initial frame, then larger sub-assemblies: pneumatics module, battery packs, drive axle, steer axle. Final assembly over 10,000 lb. Carriers move vertically to right level for operators at different heights. Suspended from above, adjusts down the line. One big loop. Some of largest carrier types in world. On cusp of producing first assemblies.

Battery marriage for long-range truck. Three battery packs in parallel, using same cells as Cybertruck. Packs are cube-shaped for high energy storage in small space, designed electric from ground up. Frame comes in, batteries nest into frame. Currently somewhat manual, will be automated. Uses torque tool for precise bolting.

Cab Line and Coatings

Cab brought in from above. Coating starts here. Adjacent to Gigafactory for EV batteries. Manufacturing melt between factories: stamping parts for that facility, injection molding parts used here, shared engineers.
