The seven-dimension breakdown (method v1.0)
Performance (20%)n/a — evidence insufficient
No independent EU-version test available; BYD 8TT official page is for the U.S. Class 8 day cab (U.S. spec), with EU heavy-truck specifications/test data missing. Gap: an independent EU-version test or official EU specifications would suffice to close it.
TCO position (20%)n/a — evidence insufficient
No EU pricing, no TCO case studies. Gap: an EU quote or TCO estimate would suffice to close it.
Price transparency (10%)1/5
Evidence: no public price for EU trucks (NOT published for EU trucks) — lowest tier in State A.
source ↗Compliance & market access (15%)n/a — evidence insufficient
EU heavy-truck market access status is “pipeline, verify current stage,” with no conclusive WVTA evidence; BYD Europe page exists but lacks EU certification or delivery evidence for heavy trucks. Gap: EU type-approval documents or delivery records would suffice to close it.
Warranty (10%)n/a — evidence insufficient
EU truck warranty terms require verification; no written terms available. Gap: written warranty terms would suffice to close it.
Service network (15%)3/5
BYD’s European commercial network exists (bus-strong), with an EU service structure, but truck-specific network depth remains unverified, hence a score of 3.
source ↗Track record (10%)3/5
Evidence: BYD’s official page confirms global yard/regional operating track record, but EU heavy-duty deliveries remain unverified, hence a score of 3.
