When sourcing a Toyota Hiace, prioritize the engine type (Diesel vs. Gasoline) based on your local fuel costs and torque requirements. For heavy-duty logistics, the 2.8L 1GD-FTV turbo-diesel engine is highly recommended for its high torque and fuel efficiency. Ensure the payload capacity aligns with your needs, typically ranging from 1,000kg to 1,200kg. Additionally, verify the transmission type (5-speed manual or 6-speed automatic) to match driver preferences and urban vs. highway usage scenarios.
