The heavy-duty Quon was developed as the flagship vehicle for UD Trucks. While integrating engine technologies, electronic technologies and eco-friendly technologies accumulated by the company, it also significantly boosted environmental performance and fuel economy via the world’s first selective catalytic reduction (SCR) system called FLENDS (Final Low Emission New Diesel System).
Redesigned from a blank page, while capitalizing on the qualities of its highly praised predecessor Big Thumb, the heavy-duty Quon hit the market in 2004 and became the company’s flagship vehicle. Quon integrated the most advanced technologies - some world-first innovations - in electronics, safety and the environment.
Although many around the world believed meeting the rigorous long-term emission regulations set to go into effect in Japan in 2005 was an impossible task, the company succeeded one year ahead of schedule, introducing a top-level urea selective catalytic reduction (SCR) system called FLENDS (Final Low Emission New Diesel System) in the exhaust gas after-treatment system. This marked a first in the industry and resulted in a substantial boost in environmental performance and fuel economy. Among its other distinguishing features, the GE13 engine mounted on Quon adopted a unit injector, with the top-end model realizing up to 520 horsepower.
The new cab design aimed to diminish fatigue on long hauls and improve driver use in other areas such as installing a front passenger seat that flips up, to allow drivers to stand up and get changed inside the cab. In terms of safety, Quon introduced a new structure that included a highly rigid cab construction and the world’s first knee airbag, as well as new brake standards to reduce damage in the event of a collision. A number of IT-driven features such as a voice-assist function and an internet-based remote checking function transformed the heavy-duty truck into a smart vehicle for the next generation.
