What is the difference between Civic National V and National VI?
2 Answers
The difference between Civic National V and National VI lies in the emission standards and emission levels. The main differences are as follows: In terms of emission standards: The Civic National V follows the National V emission standard, and new vehicle registrations have been halted in most regions of China; National VI follows the National VI emission standard. In terms of emission levels: Under the National V standard, the carbon monoxide emission for gasoline vehicles is 1000 mg/km, while under the National VI standard, it is 700 mg/km. The National VI standard is more stringent than National V, reducing nitrogen oxides by 77%, particulate matter by 67%, introducing limits on particulate number, and tightening requirements on the durability of emission control devices and on-board diagnostic systems.
The core difference between Civic's China V and China VI lies in the emission standards. China VI is the sixth-generation standard, which is significantly stricter than the fifth-generation China V, reducing pollutants like nitrogen oxides by half and emitting fewer particulates, making it much more environmentally friendly. The implementation timelines also differ: China V was rolled out around 2017, while China VI began phased implementation from 2020, with major cities now mandating China VI for vehicle registration. China VI vehicles offer slightly better fuel efficiency and smoother acceleration response, but purchasing a new car may cost 5,000 to 10,000 RMB more. For used cars, China VI models retain higher resale value, while China V models depreciate faster, especially in policy-restricted areas like Beijing and Shanghai. Maintenance-wise, China VI systems are more complex, with pricier parts but lower failure rates. Overall, China VI promotes greener transportation, aligning with the broader trend.
