F1 Power Unit

hrd_sakura_12

Under F1 power unit regulations since 2014, engines are 1.6L direct-injection 90-degree V6 turbo engines equipped with an energy recovery system (ERS), a hybrid system consisting of a motor generator unit-kinetic (MGU-K) and a motor generator unit-heat (MGU-H) system.

Fuel flow to the engine is strictly limited, demanding high output and extremely high fuel efficiency. Energy supply to the MGU-K is also limited, requiring energy management with extremely precise cooperative control between the engine and the two MGUs.

In addition, the number of power units allowed per season has been declining each years. In response, F1 drivers demand engines of high durability and reliability. Satisfying this requirement requires the application of advanced technology in every aspect of the power unit, requires the “ultimate” power unit.
