How to Tell If the Car You're Buying Meets China 6 Emission Standards?
1 Answers
China 5 emission standard is marked with a "V", while China 6 emission standard is marked with a "Ⅵ", both using Roman numerals. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. For used cars, you can check the vehicle's full model number on the environmental protection website. Details are as follows: 1. Emission Standards: The symbols for China 1 to China 6 are I, II, III, IV, V, and VI, respectively. China first introduced the China 1 emission standard on July 1, 2000. Since it was based on European emission standards and aligned with international standards, the symbols from China 1 to China 6 also adopted Roman numerals. New emission standards have been introduced every few years since then. 2. China 6 Standard: The "China 6 Standard" is divided into two phases, "China 6a" and "China 6b", with nationwide implementation planned for July 1, 2020, and July 1, 2023, respectively. However, the China 6 standard is extremely stringent, far exceeding Europe's sixth-stage emission standards and the U.S. Tier 3 standard, making it one of the strictest emission standards globally. The implementation period for the China 6 standard will also be longer.
