In case the name really is different from the international market (if you mean model names) we can use the local name like we do on many cars already.

Talking about these two brand names, let's take the Great Wall Motors logo for example:

長城汽車
Changcheng Qiche (Great Wall Motor). The logo uses both names.
Their official website is: http://www.gwm.com.cn/
No point in naming the brand Changcheng instead of Great Wall when it's the same thing


Now, Chery. Their logo shows Chery simply in latin letters:

Their official website is http://www.chery.cn/ so no Qirui
Qirui is just the pinyin transcription of the word
