A joint study from the VTT Technical Research Centre in Finland and America’s Argonne National Laboratory (ANL) has concluded that at least one third of a car’s fuel consumption is used in overcoming friction. Friction loss has a direct impact on both fuel consumption and as a result, air emissions. However, there is available technology and technology under development that will make it possible to reduce fuel consumption and emissions by 18 percent within a decade. Within 25 years, the researchers estimate fuel consumption can be reduced by over 60 percent.
