Mass reduction potential for a class-8 heavy truck


As with light duty vehicles, reduced tractive load can be achieved by lightweighting trucks so fewer trucks can carry more cargo. Lightening trucks has less benefit for mpg than in a car (20% of fuel energy moves cargo vs. ~0.3% for an auto), but greatly raises productivity for trucks with weighed-out loads.

Lightweight high-strength steel or alloys in different components throughout the tractor and trailer can save over 2,800 lb at a cost of $1–4/lb.
