What is the emission standard of the Audi A4L?

[SanLayla]

The latest Audi A4L complies with the China VI emission standard. Below is a detailed introduction to the China VI standard: Requirements and advantages of the China VI standard: The China VI standard imposes higher technical requirements on vehicles and stricter demands on components, which increases costs for some automakers. At the same time, the China VI standard sets criteria for improving gasoline quality, reducing pollutants in gasoline, making exhaust emissions more environmentally friendly. Implementation process of the China VI standard: Currently, China has divided the China VI standard into two phases: China VIa and China VIb, which were implemented in 2020 and 2023, respectively. Since July 1, 2019, the implementation of the China VI standard has imposed stricter requirements on emissions of carbon monoxide, nitrogen oxides, and hydrocarbons.

While researching the Audi A4L, I discovered that its emission standards are actually related to the model year and engine displacement. For example, older models from around 2015 typically complied with China IV or China V standards, but these are rarely seen on the market now. New cars after 2019 have been upgraded to the China VI phase, specifically China VI a and China VI b. For instance, all models from the 2022 model year onwards meet the China VI b standard. I pay special attention to this when choosing a car because in license-plate-restricted cities like Beijing and Shanghai, China VI b vehicles can be registered directly, while China V cars may face restrictions. The new standards impose stricter requirements on exhaust particulate matter, and engines are now equipped with particulate filters. Although this slightly increases maintenance costs, the higher environmental credits mean the car could fetch an extra ten thousand yuan or so when sold as a used car. In practical use, there's not much difference, and fuel consumption is actually lower due to technological optimizations.

When it comes to the Audi A4L's emissions, I've noticed significant policy impacts in recent years. The early 2.0T low-power version had China V standards, but after the implementation of China VI in 2019, most were upgraded. Currently, all new cars on sale meet China VI-b standards, especially in strictly regulated cities like Beijing, Shanghai, Guangzhou, and Shenzhen, where registering older China IV vehicles has become difficult. Compared to China V, China VI-b primarily restricts hydrocarbon and nitrogen oxide emissions, with PM2.5 emissions reduced by 90%. Manufacturers have also adjusted the engine software for faster exhaust treatment during cold starts. Therefore, new car owners don't need to worry about environmental traffic restrictions, and no one at gas stations will complain about your car's smell. In the long run, the resale value is about 20% higher than vehicles with older emission standards.

I've been driving an Audi A4L for three years, the China 6b version. This standard requires tailpipe nitrogen oxide emissions to be below 60 milligrams per kilometer, which is much stricter than older models. The advantage is that driving within Beijing's Second Ring Road won't trigger emissions violation cameras, and annual inspections pass instantly. The exhaust system is equipped with a particulate filter that self-cleans during occasional highway driving, with normal fuel consumption around 7-8 liters per 100km. When buying used, pay attention to the color of the environmental label - only green labels meet China 6 standards.
