The Ka is a city car model manufactured by Ford in Brazil, at its factory in Camaçari, previously in São Bernardo do Campo, and in Europe. The Brazilian version is exported throughout Latin America, while the European version is produced in Valencia, Spain. In Brazil, it was a subcompact in its first generation; in Europe, it also offered sporty (called SportKa) and convertible (called StreetKa) versions. In its second generation, it became a compact car. In its third generation, it began offering two body styles: hatchback (called Ka) and sedan (called Ka+).

Despite its great success in recent times, the model was officially launched in Brazil in 1997 with a rounded design and a 1.0 Endura engine. It wasn't until 2008 that the Ford KA was restyled, gaining a new, more efficient and economical Rocam engine, without forgetting the modern design. According to the American automaker, the new line features a 1.0 EcoBoost engine and another 1.6 EcoBoost for a sporty ST version.
