摘要：	A multi-laboratory, multi-university consortium has constructed a multi-year program plan with industry. The consortium has leveraged ASCI funds, utilized results of complimentary Laboratory, University and NASA internal supported efforts, in addition to buy-in, collaboration, and communications with truck industries and organizations. The Program has demonstrated several concepts and devices which meet the 25%drag reduction goal and represent a savings of 4,200 million gals per year. This is equivalent to 130 midsize tanker ships per year. Insight from experiments and experimental data base has provided clear guidance to industry on reliable, predictable experimental techniques. Computational results provide clear guidance and caution warnings on the use of steady Reynolds-averaged Navier Stokes (RANS) models for CFD simulations.
