Mercedes has developed the world's most efficient internal combustion engine used in automotive racing. With a test engine developed for Formula 1, Mercedes has exceeded thermal efficiency greater than 50%, a remarkable achievement for the automotive world.
This achievement is a result of many, many different technological strategies and improvements throughout the power unit. Two of the major strategies will be discussed in this video, which include the MGU-H, as well as pre-chamber ignition allowing for lean burning. Of course an electric car motor runs 90% to 98% efficient – i.e. internal combustion engines are inefficient dinosaurs.
