Quon was released on November 18, 2004 in Japan, as the successor of BigThumb. It is said that it was named for the term "Kuon (久遠)" with the same pronunciation, meaning "timeline forever" or "permanent". Not only equipped with SCR system, Quon was the world's first truck which has SRS knee airbag as standard equipment.
