Renault Trucks has revealed its latest research into improving the energy efficiency of diesel trucks with Optifuel Lab 3, its laboratory vehicle developed as part of the FALCON (Flexible & Aerodynamic Truck for Low CONsumption) collaborative project.

Optifuel Lab 3 combines technologies relating to aerodynamics, rolling resistance, driver assistance, energy management and the powertrain and aims to reduce fuel consumption by 13 per cent on a complete tractor-trailer combination, compared to a standard Range T truck and trailer.

Optifuel Lab 3’s technological developments will focus on optimised tractor semi-trailer combination aerodynamics, connected low-rolling-resistance tyres, predictive energy-saving driving assistance and energy management functions, as well as an improved powertrain.

The research truck will conduct its first on-road tests in 2019 and determine consumption savings assessments in 2020.
