It's only showing the top 8 groups. BYD are presumably part of the missing percentage (show it as a bar graph to see how much isn't covered).

Looking at the data in more detail, BYD are selling about half of Tesla. (85k across Europe in 2025 vs 185k for Tesla)

https://www.bike-ev.com/news/cars/byds-270-europe-sales-surg... But these numbers don't split out only EVs. So assuming these numbers are correct, BYD would be below even Geeley which seems... odd. It's probably availability bias, but I see BYD cars every day and that's not true for Geely.

For all the press, BYD isn't actually that big in Europe. As you can see, Geely (another Chinese brand, which gets very little press) is actually bigger.

If you look at the data for Spain, where they're quite big, you'll see them, but they're not getting into the top 8 for Western Europe as a whole (which is what this site shows).
