Danfoss says improvements in hydraulic system efficiency will have merit not only for battery electric vehicles, where it translates into greater range and smaller battery size, but on any system that seeks to minimize fuel consumption and reduce emissions. We recently announced a strategic partnership with Autonomous Solutions Inc.
