Increasingly complex engines require intelligent solutions. There are many considerations to be taken into account when planning and developing cooling systems for railroad vehicles, for example. The overall design of the vehicle and the available space provide the framework for the construction and installation location of the cooling system. Whether railroad vehicles are driven electrically or with diesel fuel, we have been developing innovative and functional solutions for over 70 years. High-value engine components also require strong development expertise, which, coupled with one of the most comprehensive portfolios in the industry, makes MAHLE a reliable partner for all leading engine manufacturers. We work closely with these manufacturers to develop new materials and new products: for more robust engines that are even more efficient.
