Alright, so Tesla has been pretty tight-lipped about the Semi's trim levels and specs for a while now. Like, years. But with mass production officially on the horizon for 2026, they finally pulled back the curtain and gave us the full breakdown. Better late than never, right?

Elon confirmed it on X over the weekend mass production is happening this year. And with the dedicated Semi facility in Sparks, Nevada actually standing and operational, it finally feels real. No more moving goalposts.

So here's what we're working with:

Tesla is building two versions a Standard Range and a Long Range trim. Both run the same tri-motor setup on the rear axles, same 800 kW drive power, same 1.7 kWh per mile efficiency. The big differences? Range, weight, and charging speed.

The Standard Range comes in under 20,000 lbs curb weight and gets 325 miles at full 82,000 lb gross combined weight. Charges to 60% in 30 minutes via MCS 3.2. Peak charging speed hasn't been confirmed for this one yet.

The Long Range sits at 23,000 lbs curb weight about 3,000 lbs heavier and stretches to 500 miles on the same load. The headline here is the 1.2 MW peak charging speed. That's fast. Like, seriously fast for a Class 8 truck.
Both trims also pack an ePTO (Electric Power Take Off) up to 25 kW, which is a nice touch for fleet operators who need auxiliary power on the job.

One thing worth keeping in mind there's no sleeper cabin yet. So for now the Semi is built for regional runs, not cross-country overnight hauls. That's been the play since the Pepsi and Frito-Lay pilot days and it stays true going into mass production. It's a regional freight beast first. Long-haul can come later.

Tesla hasn't disclosed battery sizes for either trim, which is a bit of a gap but given everything else they've shared, the specs are starting to paint a pretty clear picture of what this truck is capable of.

2026 is shaping up to be the year the Semi stops being a promise and starts being a presence on the road. We're here for it. 🤙
