Every comparison in European electric trucking starts at the same address: the Mercedes eActros 600. Not because it wins every specification — at 621 kWh LFP it is not even the biggest battery in class — but because it is the most-tested, most-delivered, most-referenced electric tractor on the continent, and in a market that punishes unproven claims, proof is the product.

The truck. 621 kWh of LFP across three packs, a ~500 km range claim repeatedly validated by independent testing, CCS charging at 400 kW with MCS readiness designed in, and an e-axle developed in-house. It has been delivering EU-wide since 2024, accumulating the named-fleet reference base (retailers, logistics groups, industrial shippers) that procurement teams actually call. On our scorecard it posts the current segment high: top marks for compliance, service network and track record, strong performance scores, with only per-contract warranty opacity costing it points.

The ecosystem. Mercedes’ defence against cheaper, bigger-battery challengers is everything around the truck: the densest factory workshop network in Europe, Daimler Truck Financial Services’ leasing and insurance products, Milence membership (the Daimler/Traton/Volvo charging alliance with four Belgian hubs and EU co-funding), and decades of residual-value data that make its financing maths the least speculative in the business. When a Chinese entrant offers a bigger battery at an unknown price, Mercedes’ counter is a spreadsheet of certainty.

The challenges. Price: the eActros 600 sits at the premium end, and fleets running toll-light routes can find the TCO argument thin without grants. Charging speed: 400 kW is class-adequate but will age against MCS-ready rivals. And the volume question: European plants (typically 40,000–80,000 units/yr) cannot match Chinese capacity if a price war comes.

WattTonne’s read. The eActros 600 is the control group of European electric trucking: the truck to beat, and the standard against which “cheaper” must be proven rather than claimed. Fleets should test it first — not because it will necessarily win, but because every other evaluation needs its baseline.
