The Opel Karl (also known as the Vauxhall Viva and Vinfast Fadil) is a city car with a hatchback manufactured by GM Korea and marketed by Opel as a rebadged and restyled variant of the fourth-generation Chevrolet Spark, replacing the Suzuki-sourced Agila in Opel's range. Named after Adam Opel's eldest son Carl, the city car was discontinued following the sale of Opel to PSA Group in 2019, the same year production in Vietnam started under license of a rebadged variant, the VinFast Fadil. General Motors marketed a rebadged variant in the United Kingdom as the Vauxhall Viva - this resurrecting an old Vauxhall nameplate from the 1960s and 1970s.
