Hybrid Power Unit

A Hybrid Power Unit is a powertrain system in motorsport that combines a traditional internal combustion engine with electric motor-generators and energy recovery systems to improve performance and efficiency.

These sophisticated systems capture energy that would normally be wasted during braking or from exhaust heat, storing it in batteries or supercapacitors. Drivers can then deploy this stored electrical energy as a power boost during acceleration or overtaking maneuvers, providing a strategic advantage on track.

Hybrid Power Units are used in various racing series including Formula 1 (since 2014), WEC, IndyCar (from 2024), and WRC. While adding complexity and weight, these systems deliver increased power, improved fuel efficiency, and help motorsport develop technology relevant to road cars.
