June witnessed the most plug-in electrified vehicles in one month yet sold in the United States.

In all, 13,772 PEVs were sold comprised of 7,678 battery electric vehicles and 6,094 plug-in hybrids. The previous record was in December 2015, when 13,274 were sold.

This is a count for passenger vehicles, and their combined percentage of the U.S. market share was 0.91 percent of the 1,506,256 total passenger vehicles sold last month.

By comparison, regular hybrids tallied to 27,679 sales, or 1.84 percent of the market.

Hybrid models sold in the U.S. number around three dozen vehicles, and PEVs made up of 14 plug-in hybrid models, and 12 battery electrics equal 26.

Hybrids also have an 11-year head start in the market, and PEVs are actually building on the foundation laid by these first electrified vehicles.

The dollar premium over conventional cars that PEVs require is still more, but they are eligible for federal and state subsidies, whereas federal hybrid tax credit went away several years ago when the Chevy Volt and Nissan Leaf were just two months on the market.

More PEVs are coming too, and in more type classes, including one minivan, and crossover SUVs.

Also pending are the new 200-mile-plus EVs from Chevrolet, Nissan, Tesla, and Ford and Hyundai are also expected to bring forth competitors in the sub-$40,000 range.

Cheap gas has put a damper on the market, but that is hardly the only factor limiting faster growth. More consumer education is still needed, as are more dealers able to explain the benefits of plugging in along with motivation to sell them.

The market is moving forward however, not as fast as some predicted at the end of last decade, but things are speeding up as regulations tighten, the word spreads, and other factors also create synergy.
