On August 16, the FIA World Council approved the regulations for the new power plants that Formula 1 will switch to in the 2026 season.
The details of the new regulations have long been discussed and widely known, but have now been officially approved so that manufacturers can start developing.
The powerplants keep the layout: it will be a 1.6-liter V6 with turbocharger, ERS and MGU-K.
The rejection of the MGU-H compensates for the increase in the allowable power of the hybrid part to 350 kW, which will increase the “road relevance” of hybrid power plants.
Confirmed the transition to a completely environmentally friendly fuel.
By splitting the combustion engine into two parts, the FIA gave more freedom in developing the top of the combustion chamber to optimize performance with the new fuel.
The rate of fuel delivery to the combustion engine is limited by energy, not mass or volume. Rework on the lower half of the engine (engine block, crankshaft, connecting rods, pumps and accessories) will be limited.
The interior of the engine will be dimensioned more precisely than ever before and all accessories, such as exhaust pipes that are now regularly replaced, should last the entire life of each engine.
Riders will be able to use three combustion engines and exhaust systems per season, and two MGU-Ks and energy storage, but one additional element will be allowed in the first year of the new rules.
Cost-saving measures have been announced, including maximum development hours and bench testing.
