Unlike most hybrid road cars, where the main goal is to save fuel, an F1 hybrid system is built for both speed and efficiency. Several components work together inside the Formula 1 hybrid system:V6 engine: The 1.6-liter turbocharged engine provides a large part of the car’s power. All these parts need to work together to provide the right balance between power, energy use and efficiency. Hybrid power units are a good example. The 2026 regulations continue this development by asking manufacturers to get more performance from electrical energy while also improving efficiency.
