Let's take a look at which automotive groups are the top in terms of global plug-in electric car sales (and all-electric car sales).
According to EV Sales Blog, 3,124,793 plug-in cars were sold in 2020 and over 68% of them were battery-electric.
Tesla is of course still on the top, however, its market share is decreasing (from 17% to 16%) as the market expands quicker than Tesla, and the Volkswagen Group surged from #6 to #2, to a level from which it might become #1 soon.
Actually, Volkswagen Group was #1 in the fourth quarter (191,000 VW Group vs 183,000 Tesla).
