The last hurdles have been taken for the entry of new engine manufacturers into Formula 1. With an agreement on the new power sources, according to the German publication Auto Motor und Sport (AMuS)all signals green for Audi and Porsche. The new deal will be officially announced in Turkey next week, expected AMuS.
Current manufacturers Mercedes, Ferrari, Renault and Red Bull/Honda have agreed that concessions will be made. This opens the door to the entry in 2026 of brands from the Volkswagen Group, according to AMuS the group wants to come out in the premier class with both Porsche and Audi.
Some parts of the engine remain the same, it is still the compact 1.6 liter V6 Turbo. However, the new power source will be a lot greener. CO2-neutral fuel will be used, the complicated and therefore expensive MGU-H component will disappear. The power loss due to these two adjustments is made up for with a larger battery, which will deliver 350 kilowatts instead of 120. According to AMuS that equates to 476 horsepower instead of 163.
The latter poses new challenges for the teams in terms of capturing the energy. Collecting on the front axle is not preferred, but draining such amounts on the rear axle creates a lot of braking torque, analyzes AMuS. The new rear wings are not yet powerful enough to convey that, is the presumption.
There is already a lot of thought going on about solutions. Active wings, for example, flat on the straights and standing upright, as it were, for braking. Anyway, the abolition of the MGU-H was the most important condition of the VW Group, the budget cap is still to be negotiated but the entry of new engines in F1 seems imminent.
