China is taking an aggressive stance toward curbing car pollution, banning the production of 553 car models starting yesterday.

The government in China has already taken big steps to help reduce the massive air pollution issue in the country. That includes cutting steel production, restricting the use of coal, and working on a timeline to phase out fossil fuel powered cars completely.

China has been moving toward electric cars for the last decade, putting big incentives on manufacturers to sell EVs and giving consumers incentives to buy them. It’s worked, to the point that China sold more EVs in 2016 than Europe or the U.S.

This is the first time, though, that it has told companies that they can no longer build certain models. It may be the first time that any country has banned models for their fuel consumption by name, rather than using emission or economy legislation to force manufacturers to end or improve models themselves.

News of the production halt came from the China Vehicle Technology Service Center. 553 models of passenger cars will have production halted because they don’t meet fuel consumption limits.

The full list hasn’t been made available yet, but Bloomberg reports that three of the models include FAW VW’s Audi FV7145LCDBG, the Beijing Benz BJ7302ETAL2, and Shanghai GM’s Chevrolet SGM7161DAA2.

We’ll forgive you for not recognizing those cars by name, but that’s because they’re internal model codes. Research shows that the Audi is the Q3 crossover, the Chevrolet is what we would recognize as the last-generation Cruze, and the Benz is the current E-Class model. In China, those vehicles use older powertrains that don’t meet current emissions regulations.

According to a Bloomberg source, expect more banned models to follow.

“To emphasize a cut back on energy consumption, such documents will surface frequently in the future,” Wang Liusheng said in an email. “It’s an essential move to ensure the healthy development of the industry in the long run.”
