What is the difference between the Tuyue National 5 and National 6 models?
2 Answers
The difference between the Tuyue National 5 and National 6 models lies in their exhaust emission systems: the Tuyue National 5 has higher exhaust emissions, while the Tuyue National 6 has lower exhaust emissions. Below is relevant information about emission standards: 1. China's National 6 vehicle emission standards are divided into National 6a and National 6b standards. The National 6a standard was officially implemented on July 1, 2020, and the National 6b standard was officially implemented on July 1, 2023. The National 6 vehicle emission standards are the strictest vehicle emission standards in China's history. 2. After the implementation of the National 6 standards, vehicle exhaust emissions will be reduced by more than 50% compared to the National 5 emission standards. Carbon monoxide, hydrocarbons, and non-methane total hydrocarbon emissions will decrease by 50%, and nitrogen oxide emissions will decrease by 42%. Overall, the National 6 vehicle emission standards are more stringent.
As a long-time automotive technology enthusiast, I've observed that the key difference between the Touareg's China 5 and China 6 versions lies in the emission systems. Implemented in 2019, the China 6 standard imposes significantly stricter requirements on vehicle exhaust emissions of nitrogen oxides and particulate matter, with reductions of 40% to 50% compared to China 5. This means Volkswagen has added a Gasoline Particulate Filter (GPF) in the China 6 version of the Touareg, a small device to filter out harmful substances, benefiting urban air quality and being more environmentally friendly. However, the trade-off is a slight increase in vehicle weight and theoretically a bit higher fuel consumption, though in practical driving, it's hardly noticeable, with only occasional prompts for regeneration during low-speed driving. In major cities like Beijing or Shanghai, China 6 vehicles have easier registration and direct access, while China 5 models may face restrictions or require additional procedures. I recommend opting for the China 6 version—it's more advanced, holds its value better, and contributes to environmental protection in the long run, making the slight extra cost worthwhile.
