The BYD F0@F1 is a compact supermini with the design is an unlicensed copy of the European Toyota Aygo/Peugeot 107/Citreon C1

Introduced at the 2007 Guangzhou Auto Show, it was renamed from "F1" to "F0" just before its release to avoid trademark issues with Formula One.

Powered by a 1.0L 3-cylinder petrol engine (BYD371QA) producing approximately 67 — 68 and 90 Nm of torque.

The model was criticized for low safety ratings, receiving 0 stars in a 2016 Latin NCAP test. 

While the petrol version was discontinued around 2015, BYD launched the BYD e1 an all-electric version based on the F0 chassis, under its "e series".

The F0 was succeeded in spirit by the more modern BYD Seagull electric city car.
