Tesla's Semi rollout is really a charging story

Tesla says the long-range Semi can go about 500 miles per charge, but the bigger test is whether megawatt charging can arrive fast enough for fleets.

What happened

Ars Technica, republishing WIRED, reports that Tesla has officially launched high-volume Semi production at its Sparks, Nevada factory nearly a decade after the truck was first shown.

The reported pitch is straightforward: a long-range Semi with an estimated 500 miles per charge, a standard version around 325 miles, and a fleet market watching fuel and electricity costs very closely.

The infrastructure catch

The hard part is not only the truck. Heavy electric fleets need specialized megawatt chargers that can refill large batteries in practical windows, and Ars/WIRED notes that Tesla's public charging footprint for those trucks remains tiny.

The story also lands in a messy policy and market moment: federal EV support has been cut, truck efficiency standards are under pressure, and heavy trucks still account for a meaningful slice of US greenhouse-gas emissions.
