What are the differences between Civic National V and National VI?
2 Answers
Here are the specific differences between Civic National V and National VI: 1. Emission standards: The Civic National V complies with the National V emission standard, and new vehicle registrations have been suspended in most regions of China; National VI complies with the National VI emission standard. 2. Emission levels: Under the National V standard, gasoline vehicles emit 1000 mg/km of carbon monoxide, while the National VI standard reduces this to 700 mg/km. The National VI standard is more stringent than National V, reducing nitrogen oxides by 77% and particulate matter by 67%, introducing limits on particulate number, and tightening requirements for emission control device durability and on-board diagnostic systems.
When I was choosing a car, I specifically researched the differences between the National 5 and National 6 versions of the Civic. The most obvious difference is the emission standards. The National 6 model emits about half as much harmful substances like carbon monoxide and nitrogen oxides compared to the National 5, making it more environmentally friendly. In terms of hardware, the National 6 model has an additional particulate filter in the exhaust system to make the emissions cleaner. However, this also makes the National 6 model slightly slower in acceleration at low RPMs, and the fuel consumption may be about 0.3 liters more per 100 kilometers. Nowadays, it's recommended to go straight for the National 6 model when buying a new car, especially in cities like Beijing, Shanghai, Guangzhou, and Shenzhen, where National 5 models can't even be registered. In the long run, National 6 models also have higher resale value, and the price difference when selling the car after three to five years can make up for the extra cost at the time of purchase.
