German car companies Audi and Porsche have decided to enter Formula 1, the boss of their parent group Volkswagen said on Monday. It was included in discussions over the current engine rules when they were being discussed at the beginning of the last decade, but ultimately decided against entering. Last month, the VW Board approved in principle the idea of Porsche and Audi entering F1, once the engine rules were confirmed. The architecture of the engine will be the same as now, a 1.6-litre V6 turbo hybrid. The hybrid system itself will be simplified for 2026, with the removal of the complex MGU-H, which recovers and redeploys energy from the turbocharger. The hybrid is planned to produce 50% of the total power output of the engine.
