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.).

If that is true, BYD actually gets about the same as VW.
