Kimi Antonelli starts Monza from back

Mercedes driver Kimi Antonelli will start from the back for his home Italian Grand Prix after the team chose Monza to take a full power-unit penalty. Formula 1 and Mercedes had flagged the move before the weekend, with team principal Toto Wolff saying the penalty was tied to a planned engine change and excess use of power-unit elements beyond the season allocation. Under Formula 1 rules, a driver who exceeds the permitted number of power-unit components takes a grid penalty at the first event where the extra elements are used. ### Why is Antonelli going to the back at Monza? Kimi Antonelli’s penalty stems from a planned power-unit change after Mercedes decided it needed to avoid further reliability trouble later in the season. Formula 1 said Mercedes had accepted the need to install a new power unit after technical problems earlier in the year, including the issue that forced Antonelli to retire in Barcelona. (formula1.com) Toto Wolff said on August 26 that Mercedes was “taking the full thing” with Antonelli at Monza. Wolff said the team’s calculations showed Monza was the best place to absorb the penalty, adding that Mercedes was “here to fight for a championship and not get the most PR.” (formula1.com) ### Does that mean he loses whatever qualifying result he gets? Formula 1 said the penalty would be at least 10 places, depending on the exact components Mercedes changes, and could effectively send Antonelli to the back row if the team opted for a complete overhaul. Wolff’s later comment that Mercedes was taking “the full thing” indicates the team chose the larger penalty package rather than a smaller partial change. (formula1.com) The practical effect is that Antonelli’s qualifying position will not determine where he starts if the full set of new components is fitted. Under the sporting regulations described by Formula 1, the extra elements trigger the grid drop at the first event where they are used. (formula1.com) ### Why did Mercedes pick Monza of all places? Monza’s layout is one reason Mercedes identified this weekend as the least damaging place to take the hit. Wolff said the team’s calculations pointed to Monza, and Formula 1 noted the circuit’s long straights and overtaking opportunities as factors in the choice. (formula1.com) Mercedes’ own race guide describes Monza as the “Temple of Speed,” with long straights, high slipstream potential and top speeds that typically exceed 350 kph. The team says 76% of the lap is spent at full throttle, and the run to the first corner from pole is 476 meters, all characteristics that can help a fast car recover positions.

Antonelli arrived at this stage of the season leading the championship, and Formula 1 reported on August 22 that he held a 53-point advantage over Ferrari’s Lewis Hamilton. By August 26, after Zandvoort, Formula 1 said that lead had grown to 59 points over both Hamilton and Mercedes teammate George Russell after 12 rounds. (mercedesamgf1.com) Those numbers explain why Mercedes was willing to accept a difficult Sunday at Antonelli’s home race. Wolff framed the move as a championship calculation rather than a symbolic decision about where the penalty would be most visible. ### What happens next at the Italian Grand Prix weekend? (formula1.com) The 2026 Italian Grand Prix runs from September 4-6 at Autodromo Nazionale Monza, according to Mercedes’ event schedule. Free practice begins on Friday, qualifying is scheduled for Saturday, September 5, and the race is set for Sunday, September 6 at 15:00 local time. (formula1.com) Antonelli will still take part in qualifying at Monza, but his starting spot for Sunday’s race will reflect the engine penalty rather than where he places on Saturday. Mercedes and FIA documents later in the weekend will set the final starting grid once all component changes are formally recorded. (formula1.com) (mercedesamgf1.com)
