  Tesla’s Semi is poised to revolutionize the electric truck market, industry experts say. [Image: Tesla]<\/figcaption><\/figure>\n<\/div>\n

Tesla has quietly unveiled the production-ready specs for its all-electric Class 8 truck, the Tesla Semi, on the vehicle’s official website, giving us a clearer picture of what to expect from this game-changing hauler.<\/p>\n

Electrek reports that Tesla has finalized two versions of the Semi: Standard and Long Range. These updated specs showcase the new chassis, headlights, and aerodynamic enhancements teased at last year’s shareholder meeting. The automaker is currently outfitting its Nevada Gigafactory with production equipment, eyeing a manufacturing kickoff in the first half of 2026.<\/p>\n

The Standard Semi boasts an impressive 325-mile range when fully loaded at 82,000 pounds (approximately 37 tons). Tipping the scales at under 20,000 pounds (approximately 9 tons), it’s a lightweight powerhouse. With an efficiency rating of 1.7 kWh\/mile, the truck employs three independent motors on the rear axle, churning out 800 kW. It’s compatible with MCS 3.2 charging, allowing for a 60% charge in just half an hour. The electric power take-off (ePTO) can deliver up to 25 kW for auxiliary equipment.<\/p>\n

For long-haul routes, the aptly named Long Range model offers an extended 500-mile range. It weighs in at 23,000 pounds (approximately 10 tons) and maintains the same 1.7 kWh\/mile efficiency as its shorter-range sibling. The tri-motor setup remains, still delivering 800 kW. This version supports ultra-fast 1.2 MW charging, promising hundreds of miles of range from a 30-minute pit stop.<\/p>\n

Both models are built with autonomous capabilities in mind, hinting at Tesla’s vision for a self-driving freight network. Industry watchers speculate that the 500-mile variant could pack a massive 900 kWh battery.<\/p>\n

Electrek notes that these specs align with Tesla’s previous announcements. The Standard model, with its weight-saving design, is tailored for regional and inter-hub transport. The Long Range version trades some payload capacity for extended reach, targeting cross-country electric freight operations.<\/p>\n

The Semi’s efficiency is a game-changer for fleet operators. At 1.7 kWh\/mile, it translates to roughly $0.17 per mile in energy costs, based on commercial electricity rates. This represents a dramatic savings over diesel trucks, which typically run $0.50 to $0.70 per mile. Over a million-mile lifespan, a Semi could save operators hundreds of thousands in fuel costs alone.<\/p>\n

While Tesla initially quoted prices of $150,000 and $180,000 for the 300-mile and 500-mile models respectively back in 2017, the company has yet to release updated pricing information with this latest spec reveal.<\/p>\n","protected":false},"excerpt":{"rendered":"
