BYD's expansion in the EV market is a threat to established automakers in the US, Japan and Germany, says this report in WSJ. BYD making its own batteries means it can keep costs low. It made 1.8 new energy vehicles in 2023 through August and 83% increase over 2022. It is now the largest car brand in China overtaking VW and its product mix enables it to overcome a cut in EV prices. 1 in 3 cars in China are EV's giving China and BYD the experience and scale for world wide competition.
