Currently, the Baojun RS5 on sale includes models that meet both China V and China VI emission standards. For example, the Baojun RS-5 2019 1.5T Super Internet Manual Version China VI complies with China VI standards. Below is an introduction to the China VI emission standard: Methods to check if a car meets China VI standards: Check the vehicle's conformity certificate: Every car comes with a conformity certificate upon leaving the factory, which clearly states the vehicle's emission standard. You can also refer to the accompanying vehicle list: Find the emission standard in the vehicle information section. Introduction to China VI emission standards: The standard requires a 50% reduction in carbon monoxide emissions for gasoline vehicles, a 50% reduction in total hydrocarbon and non-methane hydrocarbon emission limits, and a 42% tightening of nitrogen oxide emission limits. According to the plan, the China VI standard will be implemented in two phases: 6A and 6B. From the first phase, cars that do not meet the 6A emission standard cannot be sold, registered, or licensed. Currently, we are already in the first phase of the China VI standard. From the second phase, cars that do not meet the 6B emission standard cannot be sold, registered, or licensed.

I purchased the top-tier RS5 last year and specifically inquired about emission standards at the 4S dealership. The salesperson confirmed that all currently sold models comply with China 6b, and the yellow label under the hood clearly displays 'China VI'. Nowadays, most new cars have been upgraded to China 6b, with stricter requirements in cities like Beijing, Shanghai, Guangzhou, and Shenzhen where even China 6a vehicles are no longer eligible for registration. If you're a used car, pay special attention—models produced before February 2020 might still be China 5 compliant. The most accurate way to check is by looking at the environmental label on the top right corner of the windshield. My car runs fine on 92-octane fuel, and its fuel efficiency outperforms older China 5 engines.

Having worked in car for over a decade, I often encounter owners asking about emission standards. For the Baojun RS5, there are three scenarios: vehicles produced before March 2019 with China V standards have 'TGDI' on the rear badge; those from April 2019 to July 2020 are China VI-A models; and after August 2020, they directly upgraded to China VI-B. Here's a simple way to check the engine model: China VI-B models use the LJ0 engine, with the nameplate located on the right front door pillar. Last month, I helped a customer inspect a 2021 RS5, which had a particulate filter in the exhaust system and four oxygen sensors, clearly indicating a China VI-B configuration.

As an environmental testing station technician, I work with emission data daily. Whether the Baojun RS5 meets China 6 standards depends on its registration date: vehicles registered after July 1, 2020 must comply with China 6b (GB18352.6-2016). Test data shows the RS5's China 6b version has a hydrocarbon limit of 0.05g/km, 50% stricter than China 5. Important reminder for owners: using lower-grade gasoline can poison the exhaust oxygen sensor, and repairing excessive emissions may cost thousands. Always keep the environmental information sheet that came with the vehicle purchase.

Having focused on automotive environmental protection for over a decade, the emission evolution of the RS5 is quite representative. The early China V version used manifold injection, which was upgraded to direct injection technology in the China VI version, with fuel injection pressure increased to 350bar. The 2021 model further enhanced active grille shutters and low-friction piston rings, reducing the MIIT fuel consumption from 7.2L to 6.9L. It's recommended to check the 10th digit of the VIN: L corresponds to 2020 (China VIa), while M indicates 2021 (China VIb). Currently, some provinces allow the transfer registration of used China VIb vehicles, but China VIa models face restrictions.

Last month, I just picked up the new RS5 in Liuzhou. The manager showed me the environmental protection list, which clearly indicated compliance with China 6b (Phase VI b). I specifically compared the differences between the old and new models. The new model has an additional silver heat shield on the exhaust system, and there's a note inside the fuel tank cap that says 'Please use 92 octane or higher unleaded gasoline.' It's recommended to download the 'Motor Vehicle Environmental Protection Network' app and enter the engine number to check the specific standards. Be cautious with used cars, as some early inventory cars were sold as China 6 when they were actually China 5 during clearance sales. Always verify the vehicle conformity certificate.
