History

First Generation (2004–2017)

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.

Second generation (2017–present)

The second generation Quon was released in 2017. It has improved drivability with a new 11-litre GH11 (based on Volvo D11) and 8-litre GH8 (based on Volvo D8) diesel engine.

Third generation (2025–present)
The third generation Quon was released in 2025. The 7-speed manual model is sold using OEM from Isuzu, while the manual 12-speed model remains on sale.
