When selecting a Golden Dragon bus, you must prioritize the powertrain configuration, passenger capacity, and chassis durability. For long-distance tourism, look for models equipped with Cummins or Weichai engines paired with ZF or Allison transmissions to ensure reliability. Ensure the bus features air suspension systems for passenger comfort and integral power steering for driver maneuverability. For electric models (EVs), verify the battery energy density (kWh) and the CATL battery integration, which is a standard for high-end Chinese export buses, ensuring a range of at least 250-300km per charge.
