Tesla marked a long-delayed milestone on Thursday evening, hosting an event at its new Semi factory near Gigafactory Nevada in Sparks to celebrate the start of volume production and the first customer deliveries of its Class 8 electric truck. The Semi, first shown as a concept in 2017, is now being built at a claimed capacity of 50,000 trucks per year, or roughly 1,000 per week.
From Concept to Production Line
The road to this point has been anything but smooth. Tesla originally targeted a 2019 production start, but the timeline slipped repeatedly due to the covid pandemic and a global parts shortage. A handful of hand-built trucks were delivered to PepsiCo in 2022 from a pilot line, but true volume manufacturing did not begin until April 2026. The final production design was revealed in February 2026, following three years of refinement that shaved nearly 1,000 pounds from the vehicle.
Event Details and Notable Absence
Held at the dedicated Semi factory adjacent to Gigafactory Nevada, the Thursday evening gathering served as a coming-out party for a truck that has spent years in development limbo. Notably, CEO Elon Musk was not present; he was in Washington, DC, for a state dinner with Trump and Xi. Instead, Musk delivered a pre-recorded message in which he called the Semi the most fun truck to drive and predicted it would be revolutionary, capable of carrying the heaviest loads over long distances.
Dan Priestley, Tesla’s Director of Semi Truck Engineering, and Lars Moravy, VP of Engineering, led the presentation. Priestley emphasized that the truck’s 500-mile range figure applies to fully loaded vehicles. Moravy added that with a lighter 60,000-pound load, the Semi could reach about 600 miles.
Specifications and Engineering Upgrades
Tesla now offers the Semi in two trims: a Standard Range model with 325 miles of range at an 82,000-pound gross combination weight, and a Long Range version rated at 500 miles. The truck consumes about 1,700 Wh per mile, beating Tesla’s original target of 2,000 Wh per mile. That efficiency gain allowed engineers to use a smaller, lighter, and cheaper battery pack while maintaining range.
The Semi uses Tesla’s in-house 4680 battery cells, replacing the purchased 2170 cells used in earlier prototypes. The pack capacity is 822 kWh. The powertrain has also been redesigned with a new steel-caged rotor and a bar-wound stator shared with the Cybertruck. The drive axle is 80 kilograms lighter, and Tesla eliminated three separate oils in the original design; there is now no oil in the hub and one common oil for the motor and gearbox. Moravy said that common oil should last over 250,000 miles.
Hydraulic steering has been replaced by redundant electric power steering, and an increased wheel cut gives the Semi a turning radius nearly that of a Model Y. The system was designed for tight urban and loading-dock maneuvers. The Semi also shares an indirect thermal system with the Cybercab, including pumps, compressors, and heat exchangers. That system eliminates long refrigerant lines and moves heat between the cabin, battery, and drive unit.
Customers and Orders
First deliveries began this week, and Tesla announced a customer list that includes PepsiCo, US Foods, DHL, WattEV, ABF, Einride, IMC, and OK Produce. Most of those names had already leaked before the event, thanks to a drone-flying YouTuber who spotted the trucks at the factory.
Order momentum has been building. In August, Einride announced a 500-truck order. Earlier this week, IMC Logistics said it would buy 50 Semis for California drayage operations. On Monday, Tesla was selected by a coalition of cargo-owning shippers to supply 2,500 trucks for zero-emission freight in California.
Charging Infrastructure and Fleet Integration
Charging remains a critical piece of the puzzle. The Semi’s 822 kWh battery pack requires higher power than passenger vehicles, so Tesla is building a Megacharger system capable of delivering up to 1.2 megawatts per stall. The company says more than 30 Semi charging stations and over 200 megawatt-capable posts will be in place by the end of the year. Customer-installed overnight charging is also supported. During the event, Tesla demonstrated a 3-60 percent charge in about 30 minutes.
Tesla is positioning the Semi as an integrated fleet product. The company says its fleet has demonstrated over 98 percent uptime, compared with the 90-95 percent average for diesel Class 8 trucks. Tesla is building dedicated Semi service, mobile service, remote diagnostics, and over-the-air updates. Driver profiles follow drivers from truck to truck, and range estimates dynamically account for changing payloads.
Pricing and Cost of Ownership
One thing the event did not deliver was updated pricing. Tesla revealed no order numbers and no new prices. The rumored price for the long-range version is $290,000, a figure that Eletrek reported earlier this year. When the Semi was first introduced in 2017, Tesla quoted $150,000 for a 300-mile version and $180,000 for a 500-mile version.
Tesla emphasized lower total cost of ownership versus diesel. With diesel prices hitting record highs above $6.50 per gallon in the US, nearly double a year ago, the company argued that the Semi is cheaper to run thanks to lower energy costs and fewer parts. Moravy noted that electricity costs tend to be flat, while diesel is volatile.
Musk, in his recorded remarks, said the waiting list is significant and encouraged customers to place orders. He also called the Megacharger capable of a megawatt and said the Semi will be phenomenal.
What Comes Next
Tesla has cleared a major hurdle by getting the Semi into volume production and putting trucks in customer hands. But the company still faces challenges, including the build-out of charging infrastructure and competition from diesel trucks and other electric truck makers. For now, the wait that began in 2017 is over, and the Semi is finally on the road.
