Specification overview — e3 Mobility

Key overview parameters for this trim. Prices are Chinese domestic manufacturer guide prices, converted to US dollars at 1 US$ = ¥7.10 for orientation only — they are not export prices or local-market prices. Identifying codes — homologation model codes, motor and engine codes, manufacturer and supplier names — are published with their tail masked, so a build can still be matched without republishing the full record.
