I believe Nissan Leaf is the still the most sold electric car, more than Tesla Model 3. The Model 3 is catching up though.

Over all time Model 3 is at ~225,000 units to Leaf’s ~400,000.
So napkin math says Tesla will catch up by this time next year. I think with production acceleration due to the new China plant, it will be sooner though.
