Honda announced that it has newly developed a technology to join steel and aluminum and applied it to enable adoption of aluminum for an outer door panel, which has conventionally been made of steel. Honda will adopt this technology first to the North American version of the all-new Acura RLX, which will go on sale in the United States in March 2013, and will expand application sequentially to other models. The new technology contributes to the improvement of fuel economy and dynamic performance of the vehicle by reducing door panel weight by approximately 17% compared to the conventional all-steel door panel. In addition, weight reduction at the outer side of the vehicle body enables to concentrate the point of gravity toward the center of the vehicle, contributing to improved stability in vehicle maneuvering.
