Trucks has announced the development of a new truck concept called the Optifuel Lab. Thanks to modified front spoilers and a longer nose (about a foot (30 cm) longer than regular truck heads), the Optifuel Lab reduces diesel
fuel consumption and CO2
emissions up to 15 percent. Renault Trucks said that the tractor's powertrain was thoroughly revised, as was how the energy used to power all the auxiliary elements of the vehicle, such as electric brakes, works. It also uses a special blend of diesel fuel developed by French oil company Total. With all this, the concept truck was designed to maximize its performances on long-distance freight hauling routes and can move 25 metric tons by burning 4.5 fewer liters per 100 km.
