Is it indigenous or with west/ japan parts?

Using western or Japanese parts would mean less cost control. Its highly likely to be indigenous as far as the engine is concerned.

Design is by Changan, but Changan also has expats, foreign engineers and foreign divisions working for them. They are proud to show this.




Running an engine over 5500 RPM straight for over 10 days is most remarkable.

But... I've just browsed their main page. Their lineup doesn't look appealing to say the least. I wouldn't have said that if they hire competent designers like Geely and Haval does.

They certainly hired competent engine designers, although I would go one and equally say this about Geely.

This looks as nice as it can be for a compact SUV.

Well, this model is not shown on their website. But I have to agree that China automotive industry has come a long way. From buy and throw away car to something actually decent.

The Changan sub compact cross over also looks very decent.


Also came across a review of the Haval H6, and this looks very good to me especially the interior. The Haval H6 has been a best selling SUV in China. Earlier ones use Mitsubishi engines that were made in plants in China before Great Wall started using self branded, self engineered engines.



Chinese auto does not need to have EVs to compete against Japanese, Korean and European autos, even with ICE they can compete on their own. Due to the lack of a legacy brand image, Chinese auto will have to compete harder on value, targeting markets in Asia, Africa, the Middle East, Latin America, and Eastern Europe, instead of Western Europe, North America, Japan and South Korea.

Chinese scientists have discovered a gene that affects corn and rice yields. When this gene is knocked out or disabled, corn yields increased by 10% in test field while rice increased by 8%.

By mapping genetic markers, Li and an even larger team identified a gene that influences the number of rows of kernels in this lab-grown corn. They called the gene KRN2, for kernel row number. Two kinds of experiments demonstrated KRN2’s effects. When researchers increased the gene’s activity, plants produced cobs with two fewer rows of kernels. In contrast, when they knocked out, ordisabled, the gene, plants produced cobs with two additional rows. In field tests, knocking out the gene

北京时间3月25日凌晨,《科学》杂志在线发表了中国农业大学团队和华中农业大学团队的联合科研成果,一个在玉米和水稻中都具有的关键基因被发现。试验表明,通过对该基因的编辑改良,有望能将玉米和水稻的产量分别提高10%和8%左右。研究同时解析了玉米和水稻趋同选择的遗传规律,为作物驯化的机理解析和未来作物育种奠定了重要理论基础。
华中农业大学副校长,湖北洪山实验室常务副主任、首席科学家严建兵介绍,他们将新发现的这个关键基因命名为KRN2,通过对这一基因的编辑,可以调控玉米穗行数,从而将玉米的产量提高10%,同时这一基因,在水稻的基因组里也同样存在,进行基因编辑,它能够使水稻的产量增加8%。这是我们具有重大知识产权的基因,有可能为解决我们的粮食安全问题做贡献。
