Tesla’s Semi is beginning to prove its long-haul promise in real fleet trials, with multiple logistics companies reporting real-world trips reaching up to 500 miles on a single charge while hauling near the maximum 82,000-lb gross weight. Pilot programs from companies like DHL and ArcBest show efficiency ranging between about 1.55 and 1.72 kWh per mile, slightly better than Tesla’s original 1.7 kWh/mile target. Over thousands of test miles, fleets averaged more than 300 miles per day, with some operations needing charging only once per week. Lower energy costs are also a major highlight, with estimates suggesting electricity costs of roughly $0.12 to $0.22 per mile compared to around $0.57 per mile for diesel trucks. Tesla is expanding its Megacharger network ahead of wider deliveries expected to ramp from Nevada, though winter conditions could still reduce range by 20–40%. Early data suggest the Semi could significantly reshape long-distance freight economics if production scales as planned.
