The United States Environmental Protection Agency contracted with FEV North America, Inc. to conduct a whole vehicle analysis of the potential for mass reduction and related cost impacts for a future light-duty pickup truck. The goal was to evaluate the incremental costs of reducing vehicle mass on a body on frame vehicle at levels that are feasible in the 2020 to 2025 model year (MY) timeframe given the design, material, and manufacturing processes likely to be available, without sacrificing utility, performance, or safety. The holistic, vehicle-level approach and body-structure CAE modeling that were demonstrated in a previous study of a mid-sized crossover utility vehicle were used for this study. In addition, evaluations of closures performance, durability, and vehicle dynamics that are unique to pickup trucks are included. Secondary mass reduction was also analyzed on a part by part basis with consideration of vehicle performance requirements.

Cost-Effectiveness of a Lightweight Design for 2017-2020: An Assessment of a Midsize Crossover Utility Vehicle

In response to more stringent greenhouse gas and fuel economy standards and increasing consumer demand for fuel efficient vehicles, automobile manufacturers have identified vehicle mass reduction as a leading strategy for reducing greenhouse gas emissions and improving fuel economy. The potential for significant levels of mass reduction can only be understood using a full-vehicle analysis, partly because mass reduction in one vehicle system or part can enable additional reductions elsewhere. This paper describes a holistic approach in which the most cost-effective mass reduction ideas were selected using a structured optimization procedure, and the crash safety of the resultant design was evaluated using a full-vehicle engineering analysis.

Teardown-Based Cost Assessment for Use in Setting Greenhouse Gas Emissions Standards

The U.S. Environmental Protection Agency (EPA) contracted with FEV, Inc. to estimate the per-vehicle cost of employing selected advanced efficiency-improving technologies in light-duty motor vehicles. The development of transparent, reliable cost analyses that are accessible to all interested stakeholders has played a crucial role in establishing feasible and cost effective standards to improve fuel economy and reduce greenhouse gas (GHG) emissions. The FEV team, together with engineering staff from EPA's National Vehicle and Fuel Emissions Laboratory, and FEV's subcontractor, Munro & Associates, developed a robust costing methodology based on tearing down, to the piece part level, relevant systems, sub-systems, and assemblies from vehicles “with and without” the technologies being evaluated.
