Clean and CO2-optimized powertrain technologies reduce emissions and save fuel. They contribute to the prevention of pollution and climate change. The concepts are versatile. Hybrid drives are designed to synergistically combine the internal combustion engine and electric drive and have been on the market for about two decades. Advanced internal combustion engines designed specifically for hybrid drive can achieve higher efficiency, lower costs, and a better driving experience. Vehicles with electrical drives will achieve significant market growth in various segments in the future. In order to achieve a range comparable to combustion engines, a breakthrough in the technical development of battery cells is necessary. Scale effects in production, for example through a development towards standardized drivetrains across several vehicle platforms, will increasingly reduce the currently existing cost disadvantages and ensure the sustainable market success for this type of drive. Fuel cell technology represents another alternative drive system. A significant advantage in range over electrical drives makes this technology particularly attractive for commercial vehicle applications.
