Half of all plug-in electric vehicles (PEVs) on the road in the US in 2019 were mid-size cars. However, PEVs are available in size classes ranging from two-seaters to minivans.
Together, compact cars and large cars accounted for nearly 30% of the PEV population. Standard sport utility vehicles (SUVs) accounted for 9% while small SUVs were another 2%.
