Honda's F1 engine technologies that enable >50% thermal efficiency (global.honda)
Rather than being unrestricted, the development of power units for Formula 1 racing is governed by regulations. In 2014, the F1 adopted regulations that restricted fuel flow to a maximum of 100 kg/h to reflect the global spread of increasing environmental awareness. This meant that development had to focus on how to generate the most energy from a limited supply of fuel. In other words, it created an even greater need to pursue combustion efficiency.
