When sourcing Changan vehicles, buyers must focus on the powertrain technology, specifically the Blue Core engine series known for high efficiency and low noise. For electric models (EVs), verify the battery capacity (kWh), NEDC/CLTC range, and fast-charging capabilities (typically 30-80% in 30 minutes). Additionally, inspect the intelligent driving systems, such as IACC (Integrated Adaptive Cruise Control) and APA 6.0 (Remote Intelligent Parking), to ensure they meet the technological expectations of your local market.
