I don't know where you got your numbers from, but they're wrong. VW sold over 110K all-electric cars last quarter: https://cleantechnica.com/2021/07/21/volkswagen-group-more-than-doubles-ev-sales-in-first-half-of-2021/

And obviously quite a few more plug-in hybrids on top of that. Yes, Tesla is still currently ahead but VW isn't that far behind.
