What is the fuel consumption in Phase IV?
2 Answers
In Phase IV, the average fuel consumption of passenger vehicles in China was 5.0 liters per 100 kilometers. Research Background: After a long period of development, China's commercial vehicle market has entered a period of rapid growth in the past decade, with the development of heavy-duty commercial vehicles being particularly remarkable. However, the high pollution and high fuel consumption caused by heavy-duty commercial vehicles have also been persistent concerns. To curb the high fuel consumption of heavy-duty commercial vehicles and promote the adoption and use of clean technologies in commercial vehicles, China has introduced a series of fuel consumption limit standards for commercial vehicles over the past decade. Phase IV Fuel Consumption: The Phase IV fuel consumption standard for commercial vehicles in China is a crucial step in promoting the development of the commercial vehicle industry. The selection of driving cycles is particularly important. It is recommended to further introduce slope testing in the bench testing of fuel consumption standards, which will improve the alignment between fuel consumption standards and actual driving conditions. Additionally, it will encourage the adoption of more advanced energy-saving auxiliary technologies in new vehicle models.
When it comes to Phase IV fuel consumption, it generally refers to the fuel consumption per 100 kilometers under the China IV emission standards. There's no one-size-fits-all answer—it depends on the vehicle model and usage. For example, compact cars like the Fit or Polo might consume around 8-10 liters in city driving, dropping to 6-7 liters on highways. SUVs such as the Haval H6 could reach 11-15 liters, as the addition of catalytic converters and oxygen sensors under China IV increased engine load during exhaust treatment. However, modern technological optimizations have actually made fuel consumption lower than under older standards. Why care about this? When choosing a car, don’t just look at phase parameters—real-world driving habits matter too. The secret to fuel efficiency lies in smooth acceleration and regular air filter changes, saving money while being eco-friendly.
