Why Haas is splitting its Ferrari engine package at Monza

Haas has found itself in an awkward situation at the Italian Grand Prix, with only one of its two drivers able to use Ferrari’s upgraded engine package.

According to The Race, this is not a case of Haas choosing to withhold performance from one side of the garage for sporting reasons. Instead, the issue is practical. The upgraded Ferrari unit is only available in a way that allows one car to run it, so Haas has had to split its engine allocation between its drivers. In other words, the team is dealing with a limited upgrade rather than a straightforward, equal distribution.

That immediately creates a competitive trade-off. The driver who receives the upgraded engine should have a clearer performance advantage at Monza, but the other car is left on the older specification, which means Haas is not fielding two identically equipped machines. That can complicate the team’s ability to compare the drivers fairly, assess pure pace, and manage race strategy when one side of the garage has a better power unit than the other.

The situation also highlights how dependent customer teams are on their suppliers. Haas does not control Ferrari’s power-unit development programme, but it still has to make immediate decisions when a new specification arrives. If the upgraded engine is not available to both cars at once, the team is forced into an operational compromise that affects both fairness and performance. That is a reminder that in modern Formula 1, a customer team can be pulled into difficult choices by the timing and availability of a works partner’s upgrade.
