Key Takeaways

Tesla Semi advancing to mass production this year, confirmed by Elon Musk on X.
Two trims revealed: Standard Range (325 miles at 82,000 lbs GCW) and Long Range (500 miles).
Notable weight difference: Standard curb <20,000 lbs vs. Long Range 23,000 lbs.
Long Range peaks at 1.2 MW charging; both offer 60% range in 30 min via MCS 3.2.
Shared specs: 1.7 kWh/mi, 3 independent rear motors, up to 800 kW drive power, 25 kW ePTO.
Initially for regional/local runs, no sleeper cab yet; piloted with PepsiCo and Frito-Lay.
Dedicated production facility in Sparks, Nevada now operational.

As a veteran blogger specializing in electric vehicles and sustainable transportation, I’ve been tracking the Tesla Semi since its unveiling back in 2017. After years of delays, pilot programs, and tantalizing teases from Elon Musk, the beast is finally roaring to life. On February 10, 2026, Tesla has dropped official specs on its website and confirmed high-volume production ramp-up this year at the dedicated Sparks, Nevada facility. ❶ ❷ This isn’t just another EV hype cycle—it’s a seismic shift for the $700 billion trucking industry, promising lower operating costs, zero emissions, and performance that diesel rigs can only dream of. In this deep dive, we’ll unpack the dual-trim lineup, production realities, pilot successes, and what fleets should consider before jumping in.

The Long Road to Production: From Prototype to Factory Floor

The Tesla Semi’s journey has been anything but smooth. Unveiled with grand promises of 500+ miles of range and Megacharger compatibility, early pilots started in 2022 with PepsiCo and Frito-Lay, but mass production faced repeated setbacks due to battery supply chains, regulatory hurdles, and Tesla’s focus on Cybertrucks and Robotaxis. ❸ Fast-forward to 2026: Elon Musk confirmed over the weekend on X that high-volume manufacturing kicks off this year, with the Sparks, Nevada “Giga Semi” facility now fully standing and hiring over 1,000 workers. ❶ ❹

This 50,000-unit-per-year plant, adjacent to Gigafactory Nevada, leverages existing battery and drivetrain production for efficiency. ❺ ❻ No more excuses—Tesla’s timeline feels realistic now, with first customer deliveries slated for late 2026. ❼ My take? This timing is perfect amid rising diesel prices (up 20% YoY) and EPA mandates for zero-emission trucks by 2030.

Specs Showdown: Standard Range vs. Long Range

Tesla’s updated Semi page reveals two trims tailored for regional hauls, both optimized at 82,000 lbs gross combination weight (GCW)—the Class 8 standard. ❷ No sleeper cab yet (that’s Phase 2), keeping it lean for drayage and distribution. ❶

Standard Range: The Payload King for Daily Grinds

Range: 325 miles—ideal for urban loops under 300 miles. ❽
Curb Weight: Under 20,000 lbs, maximizing payload to ~62,000 lbs. ❸
Efficiency: 1.7 kWh/mile, sipping energy like a Prius on steroids.

This trim shines for fleets like warehouses or ports, where lighter weight means more cargo revenue. Opinion: At potentially lower upfront cost (speculated $150K-$180K), it’s the gateway drug for diesel holdouts.

Long Range: Interstate Warrior with Megacharger Muscle

Range: 500 miles—covers most regional routes without overnighting. ❽
Curb Weight: 23,000 lbs (3,000 lbs heavier due to bigger battery, est. 900 kWh vs. 600 kWh). ❾
Peak Charging: 1.2 MW (1,200 kW)—insane, refueling faster than you can grab coffee. ❼

Both trims share:

Powertrain: 3 independent rear-axle motors for tri-motor torque (0-60 in 20s fully loaded). ❷
Drive Power: Up to 800 kW. ❿
Charging: 60% range in 30 minutes via MCS 3.2 (Megacharger evolution). ❷
ePTO: 25 kW for accessories like reefers—no diesel aux engines needed.

Pro Tip for Fleets: Standard for max payload/cost savings; Long for flexibility. Run the numbers: At $0.10/kWh utility rates, TCO beats diesel by 20-30% over 5 years. ❷

Pilot Programs: Real-World Proof from PepsiCo and Frito-Lay

Tesla didn’t launch blind. PepsiCo’s fleet has logged thousands of miles since 2022, running Semis 12 hours/day on 250-450 mile routes with 99% uptime. ⓫ Frito-Lay expanded chargers at Bakersfield and added units, turning facilities into EV showcases. ⓬ Recent expansions include PepsiCo’s Denver Megacharger site. ⓭

These pilots slashed fuel costs 50% and emissions to zero, with drivers raving about regenerative braking and silent cabs. California’s $165M vouchers helped, but critics say it crowded out competitors. ⓮ Insight: Early adopters like these will get priority deliveries—sign up now.

Charging Network: The Make-or-Break Factor

Tesla’s mapping 2026 Megachargers nationwide, from Texas hubs to Cali ports. ❺ 1.2 MW means 70% range in 30 min, enabling 600-700 mile days with swaps. ⓯ Advice: Partner with Tesla for on-site installs; ROI in 2 years via lower downtime.
