And subsidies don't only affect the final price of a good: they also provide a company more funding for R&D. To say nothing of forced technology transfers via joint ventures.
The EU also still subsidizes a ton of industries, e.g. agriculture at €40.95 billion https://agriculture.ec.europa.eu/common-agricultural-policy/... (I'd agree that subsidies are needed to support a key sector like agriculture today, but they're still subsidies)
EU car manufacturers are also heavily subsidized. Subsidies are really hard do compare because you can structure them very differently and still achieve similar results (think direct loans or land leases, lower taxes, state sponsored infrastructure like rail, electricity, water, large state-sponsored orders, research grants, workforce education, consumer grants for EV vehicles, lower taxes for EV vehicles etc.).
Here's an article stating VW got over €9b over 8 years, for example: https://www.wiwo.de/politik/deutschland/dax-subventionen-gel...
If that is true, BYD actually gets about the same as VW.
