The Huansu S5 is a 5-seat compact SUV produced by Huansu, a sub-brand of BAIC Motor and Yinxiang Group.

The Huansu S5 is manufactured by Beiqi Yinxiang Automobile.

Based on the same platform as the Senova X55, the Huansu S5 is powered by a newly developed, codenamed F13B 1.3 liter turbocharged engine with 133 hp and 185 nm mated to a five-speed manual transmission or a CVT.

The same engine was later shared with the Bisu T3 and was produced by a Chongqing company called Kaite Engine.
