Tesla has confirmed final specifications for its Semi Class 8 electric truck, including Standard Range (325 miles, ~$260,000) and Long Range (500 miles, ~$290,000) variants with 1.7 kWh/mi efficiency. Following CEO Elon Musk's high-volume production announcement, the company revealed pricing via buyer outreach, fleet performance exceeding 4.6 million miles, and infrastructure expansion at its Nevada factory.
Tesla initiated Semi production updates on February 8, 2026, when CEO Elon Musk announced on X that 'Tesla Semi starts high volume production this year.' The next day, the company updated its Semi website with final specs for the redesigned truck, originally unveiled in 2017 with 300/500-mile range promises at $150,000/$180,000—now increased by ~60% due to inflation.
Both Standard Range (~325 miles loaded at 82,000 lbs GVW, curb <20,000 lbs) and Long Range (~500 miles, ~23,000 lbs curb, ~900 kWh battery) trims deliver 1.7 kWh/mi efficiency via three rear-axle motors (800 kW total), 25 kW electric PTO, improved aerodynamics, enhanced visibility windows, dual 16-inch touchscreens, acoustic damping, and autonomy readiness. The Long Range supports 1.2 MW peak Megawatt Charging System speeds, recharging 60% in 30 minutes—equivalent to six Model 3s. Operating costs are projected at $0.17/mi vs. $0.50-$0.70/mi for diesel over a million miles.
Pricing, sourced from customer communications and state voucher data, starts at ~$260,000 for Standard Range and $290,000 for Long Range (pre-tax/fees), undercutting the $435,000 industry average for rival zero-emission Class 8 trucks from Freightliner and Volvo.
Mass production begins in 2026 at the Sparks, Nevada facility (groundbreaking 2024, capacity 50,000 units/year), with hiring ramped to ~1,000 workers. Limited production started late 2022 (~200 units for Tesla/PepsiCo, which received 36); by late 2024, 100 Semis logged 4.6 million miles (one at 248,000 miles, 95% uptime).
Infrastructure includes two operational 1.2 MW Megachargers (Lathrop, CA; Sparks, NV), 64 sites mapped (Texas: 19, California: 17; focus on I-5/I-10), and partnerships like Pilot Travel Centers (20 stations). Plans cover ~20 U.S. service centers with same-day/mobile repairs, plus California’s $165 million in Semi vouchers, targeting the $700 billion trucking market.
