Hongqi H9 2022 Automatic Gasoline mileage: 10 KM A brand new Hongqi H9 car, driven about 10,000 km, has mostly been parked as I've been out of the country. It comes fully equipped with protection worth about 13,000 riyals, and the warranty continues for another five to six years. Road service is for seven years, and oil changes are covered up to 60,000 km. The inspection is a good testimony, and it has been parked inside a garage.
