What National Emission Standard Does the Baojun 310W Belong To?
3 Answers
Baojun 310W 2019 model belongs to the China VI emission standard, while the 2017 and 2018 models comply with the China V standard. The 'China [number]' refers to the national motor vehicle pollutant emission standards, which impose limits on the content of carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter in vehicle exhaust. A higher number indicates a stricter standard, resulting in relatively lower pollution levels from exhaust emissions. The Baojun 310W is a station wagon under SAIC-GM-Wuling, with dimensions of 4620mm in length, 1710mm in width, and 1535mm in height, and a wheelbase of 2750mm. The front fascia features the brand's signature U-shaped three-slat grille integrated with the headlights, a through-type lower grille design, and newly added LED daytime running lights below the fog lamps on both sides.
I bought a Baojun 310W for myself a couple of years ago, back when it was the China 5 emission standard, around 2018 if I remember correctly. At that time, I chose it because it met the emission requirements and was affordable. The China 5 standard had less strict limits on vehicle exhaust pollutants, such as slightly higher carbon monoxide and nitrogen oxide levels, which were generally fine for city driving. However, the standard was later upgraded to China 6, which is much stricter on environmental protection, reducing pollutants by more than half. If you're buying a used Baojun 310W, it's best to check the model number on the vehicle's nameplate or compliance certificate to avoid registration issues in cities that require China 6. The car is great to drive, fuel-efficient, and durable, but standards change quickly. Before buying, pay attention to the year—models produced before 2019 are mostly China 5, while those after may meet China 6. Be sure to double-check to avoid any disadvantages.
Having worked on many Baojun 310W repairs, most comply with China V emission standards. Common issues stem from the engine system's emission-focused design - China V models tend to accumulate more carbon deposits, with relatively simpler exhaust systems. Replacement parts must meet China V specifications, otherwise they'll fail annual inspections. Emission standards essentially reflect national pollution control requirements - China V has looser restrictions while China VI is stringent, forcing automakers to upgrade engines. Early Baojun 310W versions were all China V as the standard hadn't been upgraded at its 2017 launch; post-2019 production may have changed. When purchasing, don't just trust salespeople - personally check the vehicle registration or environmental label to avoid issues.
