Transparent energy flow.
Old windows that let the wind whistle through? Thin walls, or even an uninsulated roof? Energy consultants give homeowners and builders advice on where energy is unnecessarily wasted, and tell them which measures will allow them to save energy. Mercedes-Benz is likewise helped by an energy advisor when searching for lost energy: The “energy-transparent vehicle” (ETV) reveals the energy flows in a vehicle down to the last detail. During the development, an S 400 HYBRID was equipped with 300 measuring points in the powertrain and onboard electronics, and analytical software was programmed. Then it was subjected to hundreds of test cycles. This meant that the Mercedes-Benz developers were able to observe the energy flows in the engine, transmission, hybrid system and all electrical loads in real time.
“We painstakingly conducted analysis into the last nook and cranny”, says Christoph Müller, head of the consumption team. “Only in this way can we substantiate our claim to be the leader in efficiency in all performance classes.”
