• BMW EfficientDynamics heat energy recovery technology

    Even the most efficient internal combustion engine can only convert about one-third of the energy derived from fossil fuels into the mechanical kinetic energy needed to power a car. The rest of the energy is mostly wasted, either through exhaust heat, through the engine’s cooling system, or noise. Finding ways of recovering this lost heat energy is one of the major goals being pursued by engineers working on BMW EfficientDynamics for the future, something we’ve been reporting on for the past several years now but has been researched by BMW and its partners since the early part of...
