Monza always represents a significant event for Ferrari, their home Grand Prix where they aim to perform well and bring joy to their fans. For this occasion, the Scuderia has chosen to install a new Power Unit, replacing several components: the engineers have decided to change not only the engine but also the turbo, MGU-H, MGU-K, and the exhaust system, in other words, all the components on which a penalty could be avoided, leaving the control unit and battery pack unchanged.
With this decision, the Italian team has reached its fourth unit, the last one allowed by the regulations. It’s important to keep in mind that, following the World Council meeting held on April 25th, the F1 Commission and the International Federation decided to increase the number of units available to each driver for this season, going from three to four.
In fact, Ferrari had already installed its second engine in Saudi Arabia as a precautionary measure after the problems encountered on Charles Leclerc’s car during the opening weekend of the season in Bahrain. This choice was then replicated for customer teams a few weeks later in Australia.
The third engine, on the other hand, was used starting from the eighth race of the season in Canada when the Scuderia decided to install a new unit on both SF-23s on one of the most demanding circuits on the calendar concerning the Power Unit.

The decision to install the fourth engine at Monza doesn’t only extend to the Scuderia but also to Valtteri Bottas’s car, who has also reached the limit set by the regulations. The two Haas cars, in fact, took advantage of disappointing weekends in Spa and Zandvoort to incur penalties and install a fresh Power Unit to continue the season. Meanwhile, on Guanyu Zhou’s other Alfa Romeo, the Power Unit was replaced just a week ago in the Netherlands.
However, Ferrari-powered cars aren’t the only ones with a new Power Unit, as George Russell‘s and the two AlphaTauri drivers’ cars have had their engine, turbo, MGU-H, MGU-K, and exhaust system replaced. It’s worth noting that on Esteban Ocon’s Alpine, a new turbo and a new motor generator H have been installed, again without incurring penalties.
