Other records carrying the same engine code

Taotao USA certified an engine with this code under 9 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• 9TAOX0.15G2T (2009)
• ATAOX0.15G2T (2010)
• CTAOX0.15G2T (2012)
• DTAOX0.15G2T (2013)

• GTAOX0.15G2T (2016)
• HTAOX0.15G2T (2017)

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
