What are the differences between the Touareg National 5 and National 6 standards?
2 Answers
The differences between the Touareg National 5 and National 6 standards are as follows: 1. The biggest difference between the Volkswagen Touareg National 5 and National 6 models is the addition of a three-way catalytic converter, which reduces exhaust emissions. In fact, the main difference between National 5 and National 6 models lies in the exhaust emission system, specifically the three-way catalytic converter. Upgrading the three-way catalytic converter can raise the vehicle's emission standard to National 6, but owners cannot perform this upgrade themselves. These National 6 models must be produced by the automobile manufacturer. 2. Due to the influence of the National 6 emission standards, some National 5 models may see a certain degree of price reduction. Many car dealerships may implement corresponding policies, offering significant promotional discounts. The discount in the used car market might be even greater. After the implementation of the National 6 standard, vehicle exhaust emissions will be reduced by more than 50% compared to the National 5 standard. Carbon monoxide, hydrocarbons, and non-methane hydrocarbon emissions will decrease by 50%, and nitrogen oxide emissions will decrease by 42%. Overall, the National 6 vehicle emission standards will be more stringent.
I've been driving a Volkswagen Tharu with China 5 emission standard for nearly two years. Compared to my friend's China 6 version, the biggest difference is the stricter emission standards. The China 6 model has an additional particulate filter installed, making the exhaust cleaner, which is indeed more environmentally friendly for city driving. In actual driving, the power feels about the same, with no noticeable changes; but in terms of fuel consumption, the China 6 might be slightly better, saving about 5% on average during highway driving. The trouble is, the exhaust system of China 6 models is more prone to clogging, especially with frequent short-distance driving, requiring a visit to the shop for cleaning, which is less of a concern with China 5. Geographically speaking, major cities like Beijing, Shanghai, Guangzhou, and Shenzhen have long restricted China 5 models from being registered, so choosing a China 6 model is more secure whether buying used or new. Price-wise, the new China 6 models are a bit more expensive, but they hold their value much better. Overall, if you care about the environment or live in restricted areas, China 6 is the mainstream choice.
