In addition to using a sustainable fuel, the 2026 Formula 1 cars will also feature a more complex hybrid powertrain. The 1.6-liter V6 engine will be paired with an MGU-K (Kinetic Motor Generator Unit) to produce over 1000 horsepower. The MGU-K will also be able to harness the maximum amount of braking energy, producing around 320kW of power – triple the current output of the MGU-K and MGU-H systems. These technological advancements will allow the cars to use just 70kg of fuel during a Grand Prix in 2026 and the fuel flow rate will be regulated based on energy flow rather than mass or volume.
These developments in the power unit technology demonstrate Formula 1’s commitment to sustainability and innovation. The move to a fully sustainable fuel and the implementation of a more efficient hybrid powertrain will not only benefit the sport, but also have a positive impact on the automotive industry as a whole. The 2026 F1 power unit regulations represent a major step forward in the quest for more sustainable and responsible racing.
