550 km of range, 40 tonnes of combined weight and up to 800 kW of power — Tesla is already publishing these numbers for the Semi on its European website. That's why September's IAA Transportation won't just be the truck's latest European cameo. It's shaping up to be something bigger: Tesla is about to reveal the commercial details of its actual market entry.
“Specs & launch details for Semi in Europe to be unveiled at IAA Transportation in Hannover, Germany,” Tesla said. The show runs September 15–20, 2026, with a press day on September 14.
Here's the twist: part of the European spec sheet is already public. Tesla's official UK Semi page lists a roughly 550 km range for the Standard Range version, three rear-axle motors, up to 800 kW, a 9,100 kg curb weight and energy use of 1.0 kWh/km. Through MCS 3.2, the truck is meant to recover up to 60% of its range in 30 minutes; the electric PTO is rated at 25 kW.

That's already enough to line the Semi up against Europe's benchmark. The Mercedes-Benz eActros 600, at the same 40-tonne combined weight, claims 500 km without a top-up and a battery around 621 kWh. On paper, Tesla is promising roughly 50 km more — but comparing the two head-to-head before the Semi's European homologation is premature. The testing methods and configurations simply aren't the same.
Before this announcement, the truck's European future was still fuzzy: an August breakdown of the Semi pegged its Europe debut at 2027. Now there's an actual date on the calendar — one that lets us talk about order timelines, trim levels and delivery terms instead of vague promises.
Charging infrastructure matters just as much. Tesla is rolling out its Megacharger network at up to 1.2 MW, and a recent test of a new Semi-ready station showed what that kind of power actually looks like in practice. For European fleet operators, MCS availability along the highways will matter every bit as much as that 550 km on paper.
At IAA, four questions are worth watching: will Europe get a Long Range version, when will orders open, what price will Tesla set, and when will the first customer trucks actually arrive? There's no public European pricing yet.
