Daf Trucks is to display a concept rigid vehicle at The CV Show this month.
The 12-tonne LF, or Future Truck Chassis Concept, offers a 500kg weight saving on the current 12-tonne model.
Daf said the vehicle is part of its drive for fuel efficiency, lower CO2 and improve productivity.
Partly funded by the government's Innovate UK project, the vehicle was developed by Daf, Sapa Profiles UK and CSA Group.
The weight saving comes from a combination of the chassis design and lightweight materials and components.
The concept truck also features a new integrated floor and body structure, patented by Daf, which incorporates the body sub-frame into the main chassis side members.
Ron Borsboom, director of product development, said: “We continue to develop additional fuel savings and CO2 emissions reduction opportunities to maintain our cost advantage and environmental leadership.”
“Over the last decade average fuel consumption and CO2 emissions from a long-distance truck have been reduced by 14%, and we continue to reduce that even further.”
