All you need to know about F1’s new power units

Formula 1 is set for a significant overhaul in 2026 with the introduction of new power unit regulations aimed at enhancing racing and attracting new manufacturers. The revised units will be simpler, more road-relevant, and double the electrical power contribution to 50%. Key changes include the retention of the 1.6-litre turbocharged V6 engine, but the complex MGU-H will be removed, while the MGU-K becomes substantially more powerful. The sport will also fully adopt advanced sustainable fuels. This strategic shift has successfully drawn new entrants, with Mercedes, Ferrari, Red Bull-Ford, Honda-Aston Martin, and Audi confirmed as power unit suppliers. Innovations like a new 'Overtake Mode' replacing DRS and a 'Boost Button' will give drivers more tactical options on track.
