Are German manufacturers not subsidised? There are plenty of electrification grants, direct to manufactures and to consumers that end up improving sales for them
First, the subsidies to consumers for electric vehicles in Germany apply to all cars, not just those built in Europe. This effectively subsidizes the competition from China.
For subsidies to manufacturer, as I didn't quickly find any source making the direct comparison, I asked LLM to research it (I apologize for for this, but doing it manually would take too much time).
BYD: ~15% producer-focused economic benefit under the Commission's methodology; 17.0% including the legacy NEV fiscal scheme.
VW Europe: ~0.2–0.7% is my best public-data-based estimate of currently observable and allocatable producer support; roughly 0.7–1.3% if we deliberately make aggressive assumptions favorable to VW.
VW extreme stress test: ~2.5–3.2%, obtained by implausibly allocating essentially all VW Group grants and tax credits to European BEVs.
EU Commission's investigation calculated countervailable subsidy rates for Chinese BEVs: see "3.10.3. Calculation of subsidy rates" for a aggregate subsidy rates.https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=17382497...
