European Clean Trucking Alliance analysis of 91 electric tractor-trailers reveals remarkable efficiency gains 65% lower energy consumption than diesel trucks. However, battery underutilization at 44% depth of discharge creates economic challenges for cost parity. Real-world ranges exceed manufacturer specifications by up to 19%, demonstrating superior practical performance. Strategic deployment requires high daily mileage, predictable routing, & efficient charging protocols to maximize battery utilization & achieve economic viability in freight operations.
