What is the emission standard of the Great Wall M4?
3 Answers
The Great Wall M4 complies with the China IV emission standard, which stands for the National Phase IV Motor Vehicle Pollutant Emission Standard. The Great Wall M4 is a compact SUV under the Great Wall Motors brand, with exterior dimensions of 3995mm in length, 1728mm in width, and 1617mm in height, a wheelbase of 2383mm, a fuel tank capacity of 45L, and a trunk capacity of 330L. The Great Wall M4 is equipped with a 1.5L naturally aspirated engine, paired with either a 6-speed mechanical automatic transmission or a 5-speed manual transmission, delivering a maximum horsepower of 106 hp, a maximum power output of 78 kW, and a maximum power speed of 6000 rpm.
Speaking of the Great Wall M4, I've repaired many of these vehicles, and their emission standards are mostly China IV, also known as National IV. Most of the older models produced between 2013 and 2015 fall into this category. The engine is a 1.5L, paired with a simple exhaust treatment system, meeting the regulations of that time. Owners can check the environmental label on the vehicle registration certificate, which indicates the emission standard. Don’t slack on maintenance—regularly changing the engine oil, air filter, and spark plugs can help keep emissions within the standard limits. During annual inspections, exhaust emissions are often tested, and if they exceed the standard, you might need to clean the catalytic converter or repair the fuel injectors. A reminder to everyone: older cars tend to have worsening emissions, and parking in restricted zones can be troublesome. In short, with diligent maintenance, you can still drive it for a few more years, but don’t expect it to be very eco-friendly.
As an environmental enthusiast, I have paid attention to the emissions of the Great Wall M4. It meets the China IV standard, which has much higher pollution levels compared to today's China VI standards. The vehicle emits significant amounts of CO and nitrogen oxides in its exhaust, which is detrimental to air quality. If you still drive this car, I recommend using the low-emission driving mode when driving in the city or switching to public transportation to reduce pollution. China IV vehicles face driving restrictions in many large cities, such as being banned from entering certain core areas, which affects travel convenience. In the long run, upgrading to an electric vehicle or a China VI-compliant car is more environmentally friendly and also saves money and hassle. Although the M4 was affordable at the time, the environmental cost cannot be ignored. Proper maintenance can extend its lifespan, but a new car is the way forward for sustainable development.
