Real-world usage of plug-in hybrid electric vehicles: fuel consumption, electric driving, and CO2 emissions

Plug-in hybrid electric vehicles (PHEVs), which combine an electric and a conventional combustion engine drive train, offer the potential to reduce global greenhouse gas (GHG) emissions and local air pollution if they drive mainly on electricity. However, there is limited evidence on how much driving PHEVs actually do on electricity and how much conventional fuel they use in real-world operation. This report provides an analysis of real-world usage and fuel consumption of approximately 100,000 PHEVs in China, Europe, and North America.
