That is represented in the price, as the sporting regulations state the standard fee between a manufacturer and customer team is €15,000,000, making it the most expensive car part.
The price is also why some teams will not produce their own power unit, instead buying one from another constructor or outside engine supplier.
On the 2024 F1 grid, there are four engine suppliers - Ferrari, Honda RBPT, Mercedes and Renault - split amongst the 10 teams in which regulations state that a customer outfit must get the same quality engine as the factory squad.
The number of suppliers should increase in 2026 though with the arrival of Audi and the full-time return of Honda for the start of the new regulations.
In 2026, an F1 power unit will change significantly with a move to fully sustainable fuel and tweaked turbo-hybrids which includes removing the MGU-H and adding a KERS-style ‘override’ boost system.
But, looking at the current grid in 2024, which F1 team uses what power unit?
