Heavy-Duty Diesel Engine Benchmarking Program 

Competitive product benchmarking is a standard practice among engine, vehicle and component manufacturers, and has great value for evaluating state-of-the-art technology. Southwest Research Institute® (SwRI®) offers a benchmarking program based on thorough characterization of each engine and extensive testing under equal conditions. This program provides comparative data on engine performance, emissions and efficiency, as well as an assessment of emissions reduction technologies.
