Like most electric vehicles, the eTruck is relatively whisper-quiet, especially compared to a typical diesel truck. With a weight capacity of 29 US tons (26 metric tonnes), it's the first electric big rig concept to hit the road, beating out the semi Tesla has been working on that it announced last week.

Of course, big rigs move freight across long distances, so the eTruck's current 124-mile maximum range likely won't be adequate for long hauls. But the "Urban" prefix denotes its use case: As a clean, quiet load-bearing vehicle ideal for cities. Daimler has already heavily tested the utility of close-range hauling with its Fuso Canter E-Cell pilot program, sending the all-electric 4.8-tonne capacity light trucks around Portugal last fall. The eTruck scales that concept up to the loads and conditions typically endured by semis.

Daimler envisions that its electric truck won't roll off the assembly lines until early in the next decade, according to their press release. By then, technological improvements will drive battery costs down by a factor of 2.5 and efficiency up by the same metric, the truck company estimates.
