Formula 1 has yet again redefined technological advancement in the wake of more sustainable and efficient racing. The FIA world motorsport council has finally approved the 2026 Formula 1 Power Unit regulations. Well, these proclamations will keep the spirit of racing more responsible and indirectly pave the revolution for the mainstream automotive powertrain industry. The FIA in-collaboration with other PU manufacturers have drafted the regulations after extensive research and development. FIA President Mohammed Ben Sulayem is optimistically anticipating the impact of these regulations and believes," The FIA continues to push forward on innovation and sustainability – across our entire motor sport portfolio – the 2026 Formula 1 Power Unit Regulations are the most high-profile example of that mission."
Here is an in-depth analysis of what would change and how it would impact F1 motorsport :
The 2022 Formula 1 cars witnessed the move to E10 fuel, a mixture of 90percent fossil fuel and 10 percent ethanol. But now, the 2026 F1 power unit will be developed to run on a 100percent sustainable fuel, wherein no carbon emission from fossil fuels would be entertained. The fuel is intended to be extracted from waste generated, and the carbon utilised to produce that fuel would be of the same quantity as the carbon emitted from the internal combustion engine. These would indirectly mean the combustion engine would not emit additional CO2 into the atmosphere. Formula 1 has partnered with ARAMCO to develop fully sustainable fuels for this endeavour. 
The 2026 Formula 1 cars would run on a more complex hybrid powertrain, wherein its 1.6-litre V6 engine would be coupled with MGU-K (or Kinetic Motor Generator Unit) to produce 1000+ horsepower. There would be a provision to harness maximum braking energy by producing around 320kW of power from its MGU-K, which is triple the amount of electrical power produced by current MGU-K and MGU-H set. All these technological advancements will result in using just 70kg of fuel during a Grand Prix in 2026. Moreover, the fuel flow rate will be governed based on energy flow rather than mass or volume. 
The 2026 regulations will remove the current Motor Generator Unit Heat, or MGU-H set. Currently, the 2022 F1 cars are designed to such a degree that the power unit separates from the chassis without even exposing to the fuel tank. Well, now, with more complex electrical components, the vulnerability to mishaps would increase. However, to tackle those safety concerns, the 2026 Formula 1 cars will have MGU-K set to be enclosed within the chassis, next to the battery and other high-voltage equipment. All these measures are expected to make the car safer. 
The turbo lag might be a little prominent, making the cars harder to control on the corner exit. Well, of course, these changes will test the driver's capablities and would burden the management and strategists to plan and execute the power unit's electrical potential. The threat of electric waste would be taken with utmost responsibility. The F1 would mandate recycling batteries,cobalt-based material and other electrical equipment after the end of its lifecycle.
The F1 is expected to become even more intense and competitive with new manufacturers such as Audi and Porsche, hopefully entering the sport in the near future. Well, F1 is undoubtedly the pinnacle of motorsport, whose technology is further carried into road-legal vehicles by manufacturers. These innovative and environment-conscious measures would not only make F1 racing more fun and guilt-free but will also strengthen the automotive industry with sustainable technology.
