Abstract:

The authors analyzed the baseline fuel consumption, technology potential, cost, and cost-effectiveness of technology packages for five different vehicle segments, four rigid trucks and one tractor-trailer. Results suggest that improvements in internal combustion engine (ICE) technology result in fuel consumption reductions of up to 43% for rigid trucks and 49% for tractor-trailers in 2030 over model year 2022 vehicles. Hybrid technology reduced fuel consumption by 4% for the rigid trucks and 2% for the tractor-trailer, largely because they mostly operated on highways and not in stop-and-go traffic. In terms of energy consumption, electrification provided a 77% reduction for both rigid trucks and tractor-trailers.
