Tesla Semi: 'Feels like a sports car'
Elon Musk said the Tesla Semi "feels like a sports car" and described a tri‑motor layout that delivers about 800 kW of power, with two rear axles configured so the forward rear axle helps with acceleration while the rearmost axle disengages at highway speeds for efficiency (x.com). His posts about the Semi have drawn big engagement — the clip has 28k+ likes, 3k+ reposts and more than 6 million views on X, showing wide public attention to the vehicle's driving claims (x.com).
Tesla’s heavy truck uses the same basic trick as a performance electric car: electric motors deliver full pulling force from zero speed. Tesla now says the Semi’s production version uses three rear-axle motors with up to 800 kilowatts of drive power. (tesla.com) On Tesla’s Semi page, the company lists two versions: a Standard Range model rated at about 325 miles and a Long Range model rated at about 500 miles. Tesla also says the truck is designed for an 82,000-pound gross combination weight, the standard U.S. maximum for many highway tractor-trailer loads. (tesla.com) Tesla says the Semi can recover up to 60% of its range in 30 minutes and is compatible with Megawatt Charging System 3.2 hardware. The company lists energy consumption at 1.7 kilowatt-hours per mile and says the truck can charge at up to 1.2 megawatts. (tesla.com) That matters because battery-electric freight trucks live or die on three numbers: range, payload and charging time. A truck that carries less cargo, sits too long at the charger or cannot finish a regional route in one shift is harder for fleet operators to use. (tesla.com) Tesla’s own pitch is aimed at those fleet economics, not only at acceleration. The company says electricity can be cheaper per mile than diesel, maintenance can be lower because electric powertrains have fewer moving parts, and operators may reach a positive return on investment before a normal diesel replacement cycle ends. (tesla.com) The Semi has been a long rollout. Elon Musk unveiled the truck in November 2017, Tesla made its first customer deliveries in December 2022, and the company now says deliveries of the latest production configuration start in 2026. (tesla.com) (runonless.com) PepsiCo has been the most visible early customer. In September 2023, PepsiCo said its Sacramento-based Tesla Semi fleet had logged nearly 680,000 electric miles after the company took first delivery in December 2022. (runonless.com) Independent fleet testing has shown where the truck fits best so far. The North American Council for Freight Efficiency said PepsiCo’s Sacramento-based Tesla Semis completed 384 miles on a single charge and 806 miles in a 24-hour day with 750-kilowatt charging during its Run on Less depot trial. (nacfe.org) Tesla is also still building the factory and charging network needed to move from pilot fleets to broader sales. In its fourth-quarter 2025 update, Tesla said it would invest in 2026 to ramp six new production lines across vehicles, batteries, energy storage and robots, while its Semi page says customer deliveries start in 2026. (assets-ir.tesla.com) (tesla.com) The policy backdrop has shifted while Tesla has been scaling the truck. California agreed in 2025 to stop enforcing major parts of its Advanced Clean Fleets rule for private and drayage fleets and to begin repeal steps, reducing one source of regulatory pressure on diesel-to-electric truck adoption. (truckinginfo.com) So the current Tesla Semi story is less about a single boast from Musk than about whether Tesla can turn a fast, high-power electric tractor into a repeatable fleet product. The company’s own numbers now put that test on the table: 325 to 500 miles of range, up to 800 kilowatts of power, and deliveries starting in 2026. (tesla.com)
