Optifuel Lab 3
Renault Trucks wants to improve the energy efficiency of diesel vehicles
With the Optifuel Lab 3 test vehicle, the commercial vehicle manufacturer aims to significantly reduce the fuel consumption of a complete road train. Optifuel Lab 3 relies on the wide range of technologies from the broad partner consortium.
As part of the FALCON joint project, Optifuel Lab 3 combines technologies from the fields of aerodynamics, rolling resistance, driving assistance, powertrain and energy recovery. It is the result of the FALCON (Flexible & Aerodynamic Truck for Low CONsumption) project, which was selected as part of a project of the Fonds unique interministériel (F.U.I.) and is currently publicly funded. The implementation of a trailer with variable geometry is intended to improve the aerodynamics of the entire road train. The adaptive semi-trailer is to use the free space in the cargo area with the help of an integrated control system or sensors and automatically adapt its shape. The side mirrors are to be replaced by a camera system and the design of the cab pillar (A-pillar) is to be redesigned to improve the aerodynamics of the tractor unit. In long-distance transport, the rolling resistance of the tires accounts for approximately up to 25 percent of total fuel consumption, so the Optifuel Lab 3 is to be equipped with tires with particularly low rolling resistance. The drivetrain will also benefit from the latest generation of lubricants with a lower viscosity.
