Automotive Sweden is an independent non-profit organization. We spread knowledge of the Swedish automotive industry to national and international players to encourage co-operation and stimulate growth in the automotive industry.
Friction in a car's engine and mechanical components consumes a great deal of energy. Friction can be reduced by up to 80 percent with new materials and new methods of machining bearing surfaces.
Lower friction provides opportunities for fuel savings and emissions reductions. The VTT Technical Research Center of Finland and the Argonne National Laboratory in the USA have investigated vehicle friction losses. Nanotechnology and laser machining can be used to develop bearings that reduce friction.
