Much like a F1™ race car, the INFINITI Performance Hybrid technology harnesses power that is normally lost by converting kinetic energy into electricity, storing it in a lithium-ion battery system and using it during acceleration, transferring instant electric torque to the rear wheels.
The four phases of energy recovery and deployment
The Energy Recovery System (ERS) underpins the power unit of the Renault F1™ Team car. The ERS incorporates two motor generator units, the MGU-H and MGU-K, and a battery:
The MGU-K (Motor Generator Unit – Kinetic) converts the kinetic energy dissipated during braking into electricity for a boost equivalent to 120kW or 160 hp, that can be deployed to the rear wheels throughout the lap.
The MGU-H (Motor Generator Unit – Heat) converts heat energy from the exhaust gas into electricity that can be stored or used instantly for powerful acceleration until the internal combustion engine is making peak torque—an electric-energy ‘turbo boost’.
The Motor Generator Unit-Kinetic (MGU-K) is connected to the engine’s crankshaft. The MGU-K recovers kinetic energy used during braking and stores it in the battery.
The Motor Generator Unit-Head (MGU-H) directs the energy it converted from heat of the exhaust gases to the Motor Generator Unit-Kinetic (MGU-K) or to the battery.
It also responds to the air requirements of the engine and controls the turbocharger’s speed, slowing it down in place of a wastegate, or speeding it up to compensate for turbo lag.
On accelerating, the Motor Generator Unit-Kinetic (MGU-K) then propels the car with a 160 hp power boost, using power from the battery and/or the Motor Generator Unit-Head (MGU-H).
The Motor Generator Unit-Heat (MGU-H), connected to the turbocharger, converts heat from the exhaust gases into electricity and stores in the battery via an inverter.
