Tesla is finally lifting the curtain on the production-ready version of its long-awaited electric Semi truck. The company has quietly updated its official Semi website, revealing final specifications for two trims — Standard Range and Long Range — ahead of customer deliveries expected to begin in the coming months.
According to Tesla’s updated specs, the Standard Range Semi delivers an estimated 325 miles of range at a full 82,000-pound gross combination weight, while keeping curb weight under 20,000 pounds. The Long Range version pushes that figure to 500 miles, though with a higher curb weight of 23,000 pounds. Both variants share the same impressive efficiency rating of 1.7 kWh per mile, a key metric for fleet operators looking to cut operating costs.
Powering each Semi are three independent motors on the rear axles, delivering up to 800 kW of drive power. Tesla also highlights that both trims are designed for autonomy, underscoring the company’s broader push toward self-driving commercial transport. Each truck supports electric Power Take Off (ePTO) up to 25 kW, allowing operators to power auxiliary equipment directly from the vehicle.

Charging details are equally notable. Both versions support MCS 3.2 charging and can replenish up to 60% of their range in just 30 minutes. Tesla lists a peak charging speed of 1.2 megawatts for the Long Range Semi, while the Standard Range model’s peak charging rate has yet to be disclosed. Either way, the numbers point to rapid turnaround times that could make electric long-haul trucking viable at scale.
The spec reveal comes after Tesla unveiled the redesigned Semi last fall, featuring a more efficient powertrain, higher payload capacity, and a refreshed exterior inspired by the Model Y. Since then, the updated Semi has been repeatedly spotted testing near Tesla’s Semi facilities in Nevada and around the Fremont factory, suggesting production readiness has been steadily advancing.
With final specs now public, Tesla appears to be entering the home stretch. If the Semi performs as promised in real-world fleet operations, it could mark one of the most significant shifts yet in commercial trucking — and a major win for Tesla’s energy and autonomy ambitions.
