As the U.S. Environmental Protection Agency (EPA) develops programs to reduce greenhouse gas (GHG) emissions and increase fuel economy of light-duty highway vehicles, there is a need to evaluate the costs of technologies necessary to bring about such improvements. Some potential technology paths that manufacturers might pursue to meet future standards may include advanced engines, hybrid electric systems, and mass reduction, along with additional road load reductions and accessory improvements. One method of assessing the effectiveness of future light duty vehicle (LDV) technologies on future vehicle performance and GHG emissions in the near-term timeframe is through modeling assessments. |
