While the space industry seeks ways to reduce the carbon footprint of launches, ground logistics, and testing, Formula 1 is also becoming a testing ground for the energy solutions of the future. It’s important to note here that Formula 1 cars won’t be becoming hybrids—they’ve already been hybrids since 2014. Starting with the 2026 season, the championship will transition to a new generation of powertrains featuring a significantly more powerful electric component and 100% Advanced Sustainable Fuel—an environmentally sustainable fuel produced not from petroleum, but from renewable energy sources, municipal waste, and non-food biomass.
Under the new FIA regulations, the F1 powertrain will retain the 1.6-liter turbocharged V6 in 2026, but will lose the MGU-H, while the role of the MGU-K will increase significantly. The share of electricity in the total power balance is expected to rise to approximately 50%, and the capacity of the ERS-K will reach 350 kW. In addition, the FIA has already approved the mandatory use of 100% sustainable fuel, certified in accordance with strict requirements regarding the origin of raw materials and emissions throughout the supply chain.
This is not just a symbolic gesture for motorsports. F1 explicitly states that this refers to so-called “drop-in” fuel—that is, fuel that can be used in internal combustion engines without requiring any major changes to their design. This is precisely why this technology is of interest not only to the road sector but also to the transportation industry as a whole: from road construction equipment to sectors where high fuel energy consumption will remain a critical factor for the foreseeable future.
How does it work? Simply put, in 2026, Formula 1 cars will still be powered by gasoline engines and batteries, but the battery will play a much more important role. During braking, the system will recover more energy, store it, and then release it during acceleration. Instead of traditional fuel, the teams will use synthetic or bio-based fuel produced from waste, non-food raw materials, or captured CO2. In other words, the idea is to maintain speed and excitement while gradually reducing our reliance on fossil fuels.
Why is this important? For the space industry, it is of interest not as a direct substitute for rocket fuel, but as a testing ground for new technologies. F1 is involved in certifying new types of fuel, precisely managing energy flows in hybrid systems, thermal conditions, materials, and performance models under extreme conditions. These developments are closely aligned with aerospace engineering, where mass-energy balance, reliability, heat dissipation, and rigorous component testing are equally important. This serves more as a bridge to related fields in the high-tech sector than as a direct application of the technology in rockets.
