Antonelli to take grid penalty at home Italian GP as Mercedes confirm power unit change
Championship leader set for Monza setback
World championship leader Kimi Antonelli will take a grid penalty at the upcoming Italian Grand Prix, Mercedes team principal Toto Wolff has confirmed. The Italian is set to incur at least a 10-place penalty at his home race in Monza after technical issues forced Mercedes to exceed the permitted engine parts allowance.

Each driver is permitted a capped amount of various power unit parts for the season, and two separate technical issues for Antonelli have left Mercedes resigned to the fact the Italian will need to exceed the limit before the end of the campaign. Teams generally choose to incur grid penalties at tracks where overtaking is easier, which is why Mercedes are set to install a new power unit for Antonelli at Monza from September 4-6.
Standings context after the Sprint
Antonelli, who turns 20 on Tuesday, holds a 53-point lead over Ferrari's Lewis Hamilton at the top of the drivers' standings after extending his advantage over the Brit by finishing fourth in the Dutch Grand Prix Sprint on Saturday. George Russell, who reduced his championship deficit to his team-mate Antonelli to 56 points by winning Saturday's Sprint, is in a similar position with power unit parts used and is expected to need to incur a penalty before the end of the season.
Looking ahead to the rest of Antonelli's weekend after the Sprint in Zandvoort, Wolff told Sky Sports F1: "We need big points. Kimi is going to probably lose some in Monza starting in the back, so hopefully we can pocket some here."
The severity of Antonelli's punishment in Monza will depend on how many different parts Mercedes install, given he is one away from breaching the limit for several elements. The penalty will be a minimum of 10 places, but if multiple parts are installed Antonelli could be consigned to starting at the back of the grid regardless of where he qualifies.
Father hinted at the call
Before the start of the Sprint, Antonelli's father Marco had hinted to Sky Sports F1 that his son would be taking a penalty in Monza. "Monza we will see. It will be difficult, for sure - for a lot of reasons," Antonelli senior said.
