It could be said that the 2010s saw true growth in the electric car market. While automakers had sporadically introduced EVs prior to that, battery-powered vehicles slowly entered the mainstream with pioneering models such as the Nissan Leaf and Tesla Model S. As the decade rolled on, more companies started introducing their own EVs. Porsche began its first steps towards mass electrification in the mid-2010s when it showed the Mission E concept in 2015.
