VW plans to produce 1.5 million EVs per year ~in their Zwickau plant~ worldwide from 2025 onwards. They are also evaluating more plants to switch to full EV production.
Tesla expects to make 500.000 cars per year in their German plant they are currently building.
Do you have a source for that? As far as I know, Zwickau has already made its last ICE and they're targeting 1k units a day - and not seven days a week. Are you sure you're not mixing up total VW BEV numbers?
Tesla has by far the early mover advantage here; the % growth of the traditional players moving forward will be key as Big Guys start taking the market more seriously.
VW is pretty impressive, did they have any popular electric vehicle before last year?
edit: Yes, they have a massive growth indeed, if they continue like that they'll likely overtake tesla already this year: https://www.motorauthority.com/news/1130931_vw-group-sold-al...
