When sourcing the Passat, buyers must distinguish between the European B8/B9 variants and the Chinese-market variants (Magotan/Passat by SAIC-VW or FAW-VW). Key specs include the powertrain options (typically 1.4TSI, 2.0TSI, or GTE Plug-in Hybrid), transmission types (7-speed DSG is standard), and wheelbase dimensions, as Chinese variants often feature an extended wheelbase (LWB) for enhanced rear legroom. Ensure the emission standards (e.g., China VIb, Euro 6d) align with your target country's import regulations.
