Thanks to the Plug In Sites and Lanny Hartmann (who sometimes also pens a story here at InsideEVs), we can pass along the total number of registered plug-in cars in six Eastern US states.
Their total stands at 20,545, which is still not a huge number compared to the over 450,000 sold in U.S. (the bulk of which in California).
- Maryland - 6,654
- Pennsylvania - 6,581
- Virginia - 5,522
- District of Columbia - 835
- Delaware - 597
- West Virginia - 356
The common trend amongst all the eastern states is that plug-in hybrids are in majority
(in opposition to U.S. average overall). There is only 23% BEVs in West Virginia, while highest ratio of 42 to 58 was found in District of Columbia.
The average for the six is 36% BEVs (7,418) and 64% PHEVs (13,127).
