Tesla Semi nears 2026 launch: new aero, 805 km range
Tesla refines the Semi for a 2026 debut: new aero design, up to 805 km range, 1.2 MW fast charging, 800 kW triple-motor powertrain, production near Giga Nevada.

Tesla is entering the final stretch of work on the Semi: according to program lead Dan Priestley, the company is already testing the latest evolution of the electric tractor, with a market launch targeted for 2026. The Semi debuted back in 2017, pilot production started in 2022, but it never reached large-scale series output, so the truck has been substantially refreshed ahead of its commercial rollout.The headline change is the look and aerodynamics. The updated Semi gets a reworked front end, a light bar between the headlamps in the vein of Tesla’s newest models, a cleaner bumper with aero channels, a smaller windshield, and a smoother roofline. The intent is plain: reduce drag and lift efficiency on the open road. The redesign comes across as more cohesive and purpose-driven, which is exactly what a long-haul machine needs.On the numbers, the tractor is claimed to travel up to 805 km, with energy use estimated at 1.7 kWh per kilometer. Charging takes center stage too: the battery’s cooling system has been upgraded, and DC fast-charging peak power may reach 1,200 kW, enabling roughly 70% to be replenished in 30 minutes. The powertrain uses three motors with a combined output quoted at about 800 kW, and a top speed of up to 170 km/h. On paper, that recipe points to confident highway pace and compressed stops—exactly the kind of rhythm operators look for.Production is planned next to Giga Nevada at a new site, with series manufacturing expected in the second half of the year, provided the timeline does not shift.
