A simple search you know this engine only comply with China’s own GB5 standard.

That’s the reason why BMW also stop using their 3 cylinder engine and back to 4 cylinder engine to comply with GB6 standard.

TLDR: old engine which already not comply to China latest regulation in being 4 major cities. Even BMW also change their engine in their 3 series to comply GB6 standard.

Good thing is that, this engine still EURO5 compliance.

the real king is 6 cylinder
