DOE: plug-in vehicles in US displaced 323M gallons of gasoline in 2018; ~0.25%

Green Car Congress

In 2018, plug-in light-duty vehicles on the road displaced 323 million gallons of gasoline—about one quarter of a percent of all gasoline used in the United States, according to the US Department of Energy (DOE). Gasoline displacement from plug-in vehicles is about 42% more than it was in. Source: DOE.

Lithium-ion battery capacity for new BEVs sold in US reached a record high in 2019

Green Car Congress

Plug-in hybrid electric vehicles (PHEVs) accounted for a smaller portion of total plug-in vehicle battery capacity due to their lower sales volumes and because they require smaller battery packs than EVs, since they have gasoline-powered engines to extend total vehicle range.

Fraunhofer ISI/ICCT analysis of PHEV data finds real-world CO2 emissions 2-4x higher than official values

Green Car Congress

For their statistical analyses, the researchers made use of anonymized data that vehicle drivers had voluntarily reported to online portals such as Spritmonitor in Germany and MyMPG in the United States. The real-world share of electric driving for PHEVs, on average, is about half the share considered in the type-approval values.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

This is especially important for assessing the GHG emissions of PHEVs. Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either. The GHG emissions of gasoline, diesel, and natural gas cars, on the other hand, are almost identical. Source: The ICCT.
