This report summarizes the development of an on-board tailpipe emissions measurement system developed to compare the emissions and performance of two Toyota Camry model year 2010 gasoline-powered light-duty vehicles during real-world driving in Chittenden County, Vermont over multiple seasons. One vehicle, denoted as the conventional vehicle or CV, had a regular transmission and drivetrain powered solely the by a 4-stroke gasoline internal combustion engine (ICE). The second Camry vehicle, denoted at hybrid-electric vehicle or HEV, was powered by the traditional ICE in addition to the Toyota Synergy DriveR hybrid platform. To our knowledge the study is the first to compare the emissions and performance of a HEV to its conventional counterpart of the same manufacturer and model design. Thus, the emissions and performance results of this study are important to evaluating the real world, in-use benefits of this HEV technology. Gas-phase and particle number emissions as well as fuel economy performance results are presented here by vehicle specific power (VSP) and MOVES operating model classification schemes to enable comparison to other studies.
