The Baojun 310w complies with China 6 emission standards, which refer to the National Sixth Stage Emission Standards for Motor Vehicles. These standards are established to control vehicle pollutant emissions and improve ambient air quality. Taking the 2020 Baojun 310w as an example, its body structure is a 5-door, 5-seat station wagon with dimensions of 4620mm in length, 1710mm in width, and 1535mm in height. It has a wheelbase of 2750mm, a fuel tank capacity of 40 liters, and a curb weight of 1206kg. The 2020 Baojun 310w features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 105PS, a maximum power output of 77kW, and a maximum torque of 135Nm. The vehicle is paired with a 5-speed mechanical automatic transmission.

When I bought a car last year, I specifically checked the emission standards of the Baojun 310W. This model varies by production year. Vehicles manufactured before July 2019 comply with China 5 emissions, while those produced after July 2019 have been upgraded to China 6b. The exact standard can be confirmed by checking the environmental information on the vehicle's conformity certificate. Currently, most regions require China 6 compliance for registration. I strongly recommend verifying the seller's environmental certificate when purchasing a used car. Emission standards not only affect registration but also impact resale value and future annual inspections. The easiest way to check for China 6 compliance is to look at the environmental label sticker on the windshield or call the manufacturer's customer service with the VIN for verification.

Recently, while helping a friend look for a used Baojun 310W, I noticed a key point: this car has two batches of emission standards. The older National V models have bigger discounts, but many cities restrict their transfer. The newer National VI models are scarce but unrestricted. The identification method is to open the engine hood and check the production date label. Cars from the second half of 2019 mostly come with a particulate filter, and there are subtle adjustments to the rear suspension structure. National VI models have more stable idling and lighter exhaust smell during cold starts. Before buying, remember to check local policies—for example, Hebei and Shandong banned the transfer of National V cars last year. You can also enter the license plate number on the environmental protection website to get accurate information.

All newly produced Baojun 310W models now meet the China 6b emission standard. The 4S shop had already put blue labels on their display cars last year. For existing owners who want to check, it's very simple: flip to item 49 "Emission Standard Code" on the Vehicle Conformity Certificate - GB18352.6-2016 indicates China 6. During annual inspections, reading OBD data streams with a diagnostic tool to check SCR system parameters is more reliable. Pay special attention when purchasing parts - oxygen sensors for China 5 and China 6 models are not interchangeable. Currently, some cities offer replacement subsidies for China 6 vehicles and have more relaxed traffic restriction policies.
