Friends who want to buy a X1 but are worried about it not meeting the China VI emission standard can rest assured. It is understood that some models of the BMW X1 have already passed the China VI emission standard certification. In China, automobile emission standards are basically updated every three years. The China VI standard is the "Sixth National Standard for Motor Vehicle Pollutant Emissions". Compared to the China V standard, the China VI standard will strictly control pollutant emission limits. According to relevant regulations, the China VI standard was officially implemented on July 1, 2019. From July 1, 2019, newly registered light-duty vehicles will comply with the China VI-A emission standard, and stricter emission standards are encouraged.

I bought a X1 when I changed my car last year and researched its emission standards. The current new X1 models on the market all comply with the China 6b standard, especially those produced after 2020. The 2019 model was a transitional period when some versions were upgraded to China 6, and now there are basically no China 5 cars being sold. When I bought the car, I specifically checked the environmental checklist, which clearly marked the China 6 standard code GB18352.6-2016. I recommend paying attention to the production date on the nameplate near the co-driver's door frame and choosing models from the second half of 2019 onwards for more assurance. This way, you won't have to worry about registration issues in restricted areas, and the resale value will be higher.

As a long-time enthusiast following the automotive market, the X1 began complying with the China 6 emission standards after its mid-cycle facelift in 2019. The China 6 standard is divided into two phases, a and b, and the X1 currently meets the more stringent China 6b requirements. It's worth noting that pre-2018 models were still under the China 5 standard, but inventory of those vehicles has basically been cleared. To distinguish, the new X1 has added a particulate filter to the exhaust system and optimized the three-way catalytic converter. When purchasing a car, remember to check the vehicle conformity certificate and the environmental protection vehicle list, where the emission standard column is clearly stated. Additionally, it should be noted that all engine variants meet the standards uniformly, with no difference in environmental standards between the 1.5T and 2.0T versions.

When helping a friend choose a car, I researched the emissions of the X1. The facelifted models produced from July 2019 onwards fully comply with the China 6b standard, which is currently the strictest emission level. When buying a used car, pay special attention—models manufactured before 2018 are generally China 5 compliant. Verifying the standard is simple: ask the owner for a copy of the vehicle registration certificate, which contains the recorded emission level information, or check the vehicle conformity certificate—models labeled 'China VI' in the pollutant emissions section are compliant. It's recommended to prioritize newer models equipped with a particulate filter for cleaner and more environmentally friendly exhaust systems in daily use.

During my work at the dealership, I came across many X1 models. From an environmental technology perspective, the current models are all equipped with B-series modular engines that meet the China 6b emission standards, achieved through optimized combustion chambers and upgraded exhaust treatment systems. I recall that all batches produced after September 2019 completed the transition, and the sales system can check specific emission parameters. For owners, China 6-compliant vehicles not only enjoy unrestricted driving in major cities but also have lower maintenance costs for the after-treatment system. When purchasing, pay attention to the new models with engine codes starting with B38/B48, as these were designed from the outset to meet China 6 requirements.

Having reviewed BMW's official technical documentation, the current X1 model meets the China 6b emission standards right off the production line. The key lies in its upgraded fuel evaporation control system and oxygen sensor accuracy, which reduce tailpipe pollutants by over 30%. In practical use, I've noticed that the China 6 version emits more water from the exhaust pipe during cold starts, which is an indicator of high catalytic efficiency. It's advisable for owners to pay attention to the environmental label—the yellow sticker on the windshield displaying 'VI' confirms compliance. By the way, some regions offer purchase tax incentives for China 6-compliant vehicles, so remember to inquire about local policies when to save a significant amount of money.
