Image: Tesla Tesla officially launched high-volume production of the Tesla Semi last night at its dedicated new factory in Nevada, a plant it says can make 50,000 electric trucks a year. The Class 8 truck was introduced in 2017 and production was promised for 2019. Seven years later, Tesla says deliveries “start now” and detailed a heavily redesigned truck in a string of 13 posts on the According to Tesla, the plant covers 1.8 million square feet and manufactures all variants (standard, long-range and a European specification) on the same line. Tesla called it “our first factory built for Semi.” Advertisement: Scroll for more content Tesla semi-factory in Nevada (Image: Tesla) Tesla leaned heavily on vertical integration. It says it stamps parts and makes the batteries, drive axles, high-voltage distribution, cooling modules and even the seats in-house, while “most truck plants just assemble.” It also claims the first powder-coated Class 8 truck and one of its most automated battery lines to date. “Vertical integration is the only real way to reduce costs,” Tesla wrote. 4,680 cells, a more economical motor and electric steering The truck itself has changed a lot since PepsiCo got the first hand-built units in late 2022. Tesla says it spent four years redesigning the Semi “to achieve real volume.” The biggest change is the battery. Tesla went from 2,170 cells to its internal 4,680 cells, which it says means “less battery mass and less kWh without compromising range.” Tesla did not give a new package size. When it released the Semi’s final specs in February, it listed 325 miles for the standard range and 500 miles for the long range at 82,000 pounds, consuming 1.7 kWh per mile. The semi-drive unit now uses a steel-cage rotor and bar-wound stator shared with the Cybertruck (Image: Tesla). The transmission was also reworked. Tesla swapped out the carbon fiber-sleeved rotor for a steel-cage rotor, which it claims is cheaper, more reliable, and more efficient. The bar-wound stator is now shared with the Cybertruck, a part that Tesla already builds in volume. Tesla also says the Semi is the first heavy-duty truck with electric steering, which eliminates hydraulic pumps and fluids that leak and need service. And he’s candid about why that’s important beyond maintenance: “It lays the foundation for future autonomy.” Thermal management now goes through what Tesla calls a “Megamanifold,” a heat pump that handles the cabin HVAC in addition to all powertrain heating and cooling. It is the same thermal system that Tesla uses in Cybercab. Image: Tesla Inside, there’s acoustic glass, a pop-up window, and a stand-up cockpit. Tesla also automated parts of the pre-trip inspection and can generate electronic records of when those checks were performed. This is a real quality of life feature for drivers. Uptime, Charging and Diesel Math Tesla claims its Semi fleet has had more than 98% uptime so far in 2026 and says the truck is “almost maintenance-free.” In a Megacharger, Tesla says drivers regain up to 60% of their range in 30 minutes. He shared a map of Megacharger sites along major freight corridors, heavily concentrated in California, Texas and the East Coast, with large gaps in the Mountain West and Plains. Tesla Megacharger sites along US charging routes (Image: Tesla) Tesla’s economic argument came down to a graph: fuel cost per mile for a diesel truck at 7 mpg versus a Semi at 1.7 kWh per mile using transportation electricity rates. Fuel cost per mile: diesel at 7 mpg vs. semi at 1.7 kWh/mi (Image: Tesla) According to Tesla’s chart, diesel has risen again to about $0.80 per mile this year, while electric has remained in the $0.20 to $0.30 range. That gap is the entire selling point and will widen in 2026. Who’s buying Deliveries begin now, according to Tesla, which also says it will use Semis to transport its own cargo. Image: Tesla customer trucks at the event carried logos of PepsiCo, DHL, US Foods, ABF, Einride, IMC Logistics and WattEV, among others. The biggest one came earlier this week: The ZET SCALE alliance tapped Tesla as the primary supplier for 2,500 electric trucks, an order that would nearly double the number of Class 8 electric trucks on U.S. roads. This follows Einride’s order for 500 trucks in August. The price is also a big plus. Tesla hasn’t confirmed pricing since the event, but Electrek previously reported that Tesla has been quoting $290,000 for the 500-mile Semi and around $260,000 for the standard range. That’s about 60% more than the $180,000 Tesla announced in 2017, but still about $145,000 below the average price of a Class 8 electric pickup truck. Electrek Opinion As I’ve been saying for years, the Tesla Semi is the latest Tesla vehicle program I’m excited about, and despite many delays, it’s finally here. The Semi is real, it’s being produced in volume, and on paper it’s the best Class 8 electric truck you can buy. It’s six figures cheaper than the competition and the efficiency claims have held up for fleets like PepsiCo. Tesla can clearly build the trucks. Now it has to sell them, and the Megacharger network has to fill up fast enough outside of California and Texas for long-haul routes to work. Diesel at $0.80 a mile helps a lot. We will be watching delivery numbers closely over the next few quarters. If Tesla ships 5,000 Semis in 2027, it will be a real deal. If you ship 1,500, that factory will look awfully big. If you’re following the shift toward electric trucks, the same math that makes the Semi work (cheap electrons outperforming expensive fuel) also applies at home. With electricity rates increasing nearly 10% last year and expected to continue rising, solar energy is one of the best ways to protect yourself against rising costs. And with leasing and PPA options, you can do it with no upfront cost and start saving right away. If you want to find the best deal, check out EnergySage.
