What you need to know:
- Tesla has released Tesla Semi final specifications on its official product page, confirming the electric Class 8 truck is nearing customer deliveries ahead of production launch.
- The Tesla Semi Standard Range and Tesla Semi Long Range variants offer 325-mile range and 500-mile range, each rated for 82,000-pound gross combination weight with a three-motor electric powertrain.
- Key performance highlights include 1.7 kWh per mile efficiency, 800 kW drive power, MCS 3.2 charging, and up to 1.2 MW fast charging enabled by V4 Supercharger technology.
- Tesla says the truck is built for autonomy, with self-driving freight potential, while Gigafactory Nevada remains on track for Tesla Semi production 2026, with pricing expected to stay competitive with Class 8 diesel trucks.
Tesla has published the finalized specs for its upcoming production Semi, updating the truck's official product page ahead of the first customer deliveries, which will supposedly get underway this year.
As expected, the pure battery-electric Class 8 Semi will launch in two configurations, Standard Range and Long Range, marking the clearest picture yet of what buyers can expect from the long-delayed vehicle.

The update follows Tesla's reveal of a refreshed Semi design at last year's annual shareholder meeting, where the company showcased a reworked chassis, revised lighting, and aerodynamic improvements. While production timelines slipped (multiple times) as Tesla completed tooling and equipment installation at its Nevada facility, the company said in April that the factory remains on schedule to begin volume production in the first half of 2026.
Tesla Semi final specs
It's been nearly nine years since Tesla CEO Elon Musk unveiled the Semi concept. The final specs (finally!)—each with with an 82,000 lbs. gross combination weight—can be viewed below:
Standard Range:
- Approximately 325 miles of range
- Powertrain: Three independent motors on rear axles
- Curb weight under 20,000 lbs
- 1.7 kWh/mile energy consumption
- Drive power: Up to 800 kW
- Charge type: MCS 3.2
- Fast charging: Up to 60% charge in 30 minutes
- Electric Power Take Off (ePTO) up to 25 kW
Long Range:
- Approximately 500 miles of range
- Powertrain: Three independent motors on rear axles
- Curb weight of 23,000 lbs
- 1.7 kWh/mile energy consumption
- Drive power: Up to 800 kW
- 1.2 MW peak charging speed (more details below)
- Charge type: MCS 3.2
- Fast charging: Up to 60% charge in 30 minutes
- Electric Power Take Off (ePTO) up to 25 kW
Future autonomy and charging speed
Tesla adds that both Semi configurations have been engineered with autonomy in mind, hinting at eventual plans for self-driving freight operations. The company offered no timeline, and given the years it's taken to bring the Semi to market, expectations should remain measured.
Another notable takeaway is the Long Range model's peak charging speed of 1.2 MW. This aligns with a video released late last year that showed Tesla engineers demonstrating a V4 Supercharging session where peak power rose to 1.2 MW (1,206 kW).

Tesla Semi final pricing?
Unfortunately, Tesla has yet to announce the Semi's final pricing, figures that have surely changed since Musk said in 2017 both versions will begin at $150,000 and $180,000 for the Standard and Long Range versions, respectively.

More likely than not, prices will rise, but they're expected to remain broadly comparable to a new Class 8 diesel alternative.
Despite this omission, Tesla remains committed to deliveries getting underway in 2026. Series production will take place at a now-completed Gigafactory in Nevada.
