S.3 Engine Study Group Information Report 2018-02: TMC Engine Performance Study

TMC’s “EPA 2007/2010 Engine Report Card” results were based on data from 23 fleets representing 157,541 power units of the U.S. trucking industry. Of these Class 7 and 8 power units, 24 percent were equipped with EPA 2010 engines, 29 percent were equipped with EPA 2007 engines, and 30 percent were equipped with EPA 2004 engines. The survey was administered in November and December 2011 and sent to more than 600 fleets whose representatives held membership in TMC as Fleet Executive level members. The purpose of the survey was to compare the durability, efficiency and costs of EPA 2010 engines with EPA 2007 engines and EPA 2007 engines with EPA 2004 engines by fleet experiences.
