Battery electric vehicles had stronger sales than plug-in hybrids in Europe for the first time in six quarters, according to a new report.

The European Alternative Fuels Observatory just released findings of its study analyzing plug-in electrified vehicle sales in European Union member nations since 2014. While plug-in hybrid electric vehicles had dominated the market since 2015, during the first quarter of 2017, BEVs broke the pattern by slightly passing by PHEVs in total sales.

April’s sales report shows some of the models doing well in each segment, with the Renault Zoe, Nissan Leaf, and BMW i3 leading the way for BEVs. On the PHEV side, the Mitsubishi Outlander has been the strong seller, followed recently by the Mercedes GLC350e and Volkswagen Passat GTE.

The study removed sales data from The Netherlands to get a clearer picture of the overall market. The Netherlands for years has had PHEV-friendly incentives, tipping the scale in that direction. If that data were to be removed, PHEVs would only have outsold BEVs in 2016 with only two quarters that year – the second and third – showing real dominance by PHEVs.

Researchers also looked into the types of fast charging technologies that have been utilized in Europe since 2011. CHAdeMO had dominated the rankings until 2016, with more of balance now being seen between it and the DC combined charging system (CCS). The Tesla Supercharger is also making more of a name for itself in that market.

Strong sales of the Mitsubishi Outlander PHEV had been giving CHAdeMO the lead for quite a while. Japanese automakers such as Mitsubishi and Nissan have been following CHAdeMO for its fast charging systems.

During April, plug-in electrified vehicles made up 1.4 percent of new vehicle sales in Europe, a 6-percent growth over March.

PEVs saw a reverse in the sales trend, taking the lead in April. BEVs had 7,453 units sold in April, following PHEV’s lead at 10,050 units sold.
