Tesla has quietly updated its official Semi website with final specifications for the production version of its all-electric Class 8 truck, confirming two trim levels — Standard Range and Long Range — as customer deliveries approach. The spec update comes after Tesla unveiled the redesigned Semi at last year’s shareholder meeting with a new chassis, updated headlights, and improved aerodynamics. Production was pushed into 2026 as the company continued installing equipment at its Nevada factory, which Tesla said in April was on track for volume production in H1 2026.
According to the updated Tesla Semi website, here’s what the production truck will offer: Standard Range: The 325-mile range option is consistent with what Elon Musk confirmed back in 2022, implying a roughly 900 kWh battery pack for the 500-mile version. The curb weight of under 20,000 lbs makes it an attractive option for most fleets. 7 kWh/mile, which is consistent with Tesla’s previous claims.
70/mile for diesel. The Long Range model sacrifices about 3,000 lbs of payload for the extra range, but it still opens up the possibility of all-electric long haul trucking for lighter loads. With volume production confirmed for this year and these final specs now public, Tesla appears ready to start disrupting the $700 billion trucking industry.
The question now remains the price. As the first all-electric Class 8 truck, the Semi has the potential to revolutionize the way goods are transported in the US. Its efficiency and range make it an attractive option for fleets looking to reduce their carbon footprint and operating costs.
With its advanced technology and sustainable design, the Tesla Semi is poised to make a significant impact on the transportation sector.
The Tesla Semi's impressive specs and efficient design make it an attractive option for fleets looking to transition to electric vehicles. However, the pricing will be crucial in determining the truck's viability in the market.
