Light Truck Fuel Economy by Design Efficiency

CAFE (Corporate Average Fuel Economy) requirements were authorized for both “Cars” and “Light Trucks” as a result of the “Energy Policy and Conservation Act” of 1975. This paper addresses the methods by which fuel economy may be increased by design efficiency of Light Trucks in consideration of legislated goals and considers aerodynamic and road load improvements, weight reduction, powertrain selection, and optimization. In selecting the optimum fuel efficient design, adequate consideration must be given to emissions, structural durability, performance constraints, and consumer acceptance and not to forget manufacturing constraints and lead time considerations.
