The race to build an electric heavy truck just got another contestant, and Wednesday they seized the lead.

Upstart Nikola Motor Company and Tesla seemed locked in a battle to roll out the first electrified truck, but Daimler Trucks has rolled out its Mercedes-Benz Urban eTruck, the first fully electric truck with a total weight of up to 28 tons. Stefan Buchner, head of Mercedes-Benz Trucks, says the market launch of this technology is conceivable by the beginning of the next decade.

“Electric drive systems previously only saw extremely limited use in trucks. Nowadays costs, performance and charging times develop further so rapidly that now there is a trend reversal in the distribution sector: the time is ripe for the electric truck,” says Dr. Wolfgang Bernhard, who responsible for Daimler Trucks & Buses at the Board of Management. “And with the Mercedes-Benz Urban eTruck, we are now electrifying the heavy distribution segment up to 26 [metric tons]. We intend to establish electric driving as systematically as autonomous and connected driving.”

The Mercedes-Benz Urban eTruck is based on a heavy-duty, three-axle short-radius Mercedes-Benz distribution truck but developers revised the drive concept.

The entire conventional drivetrain was replaced by a new electrically driven rear axle with electric motors directly adjacent to the wheel hubs—derived from the electric rear axle which was developed for the Mercedes-Benz Citaro hybrid bus. The power is supplied by a battery pack consisting of three lithium-ion battery modules resulting in a range of up to 125 miles—enough for a typical daily delivery tour. The batteries are housed in a crash-proof location inside the frame.

The cost of fully electric drives systems, coupled with their low mileage range, has made the venture prohibitive until recently. Daimler Trucks expects the costs of batteries to lower by a factor of 2.5 between 1997 and 2025—from $550/kWh down to $220/kWh. At the same time, performance is forecast to improve by the same factor over the same period—from 80 Wh/kg up to 200 Wh/kg.
