What are the differences between the Tharu National 5 and National 6 standards?
2 Answers
The difference between the Tharu National 5 and National 6 standards lies in the exhaust emission system: the Tharu National 5 has higher exhaust emissions, while the Tharu National 6 has lower exhaust emissions. After the implementation of the National 6 standard, vehicle exhaust emissions will be reduced by more than 50% compared to the National 5 standard, with carbon monoxide, hydrocarbons, and non-methane total hydrocarbon emissions decreasing by 50%, and nitrogen oxide emissions decreasing by 42%. The National 6 vehicle emission standards are stricter. The Tharu has a body length of 4453mm, a width of 1841mm, a height of 1632mm, a wheelbase of 2680mm, and a height of 1620mm excluding the roof rack.
The main differences between the Touareg National 5 and National 6 models lie in their emission standards. National 6 is stricter, requiring lower emissions of pollutants such as nitrogen oxides and particulate matter. Volkswagen has implemented technical upgrades for the National 6 version, including a more precise engine control system and the addition of a particulate filter to reduce exhaust soot. This makes the National 6 model smoother during acceleration, though it may slightly increase fuel consumption compared to the National 5 version. In daily driving, the National 6 model offers more refined responsiveness, making it better suited for congested urban conditions. Maintenance-wise, the filter requires regular inspection and replacement, adding a bit to the upkeep cost, but overall performance remains stable. In the long run, National 6 helps reduce air pollution and complies with new environmental regulations. Having driven a friend's car, I noticed the National 6 model starts more quietly. In summary, if you prioritize environmental concerns and future licensing policies, National 6 is the better choice, even though the initial purchase price might be slightly higher.
