How a Post-Race Penalty Robbed Cadillac of Its First F1 Point at a Chaotic Monaco Grand Prix

The stewards' review concluded that the front-right wheel of Perez's Cadillac was outside of his designated starting box when the race resumed . This is considered an out-of-position infringement, which typically results in a drive-through penalty during the race but is converted to a 10-second time penalty when applied post-race .

The 10-second penalty dropped Perez from 10th to 15th in the final classification, the last of the classified finishers . As a direct consequence, the single championship point was transferred to Aston Martin's Fernando Alonso, who was elevated to 10th place .

Crucially, this was not the first error of its kind for Perez in the same grand prix. Earlier in the race, he had lined up incorrectly on the original starting grid, for which he received a drive-through penalty . The repeat error on the restart deepened the disappointment for the American outfit, which also saw its other driver, Valtteri Bottas, fail to finish the race .

Antonelli's Masterclass Amid the Chaos

While Cadillac dealt with frustration at the back, Kimi Antonelli delivered a flawless performance at the front to win his fifth consecutive race of the season . The Mercedes driver started from pole position and led every lap, building a commanding lead of more than 20 seconds at one stage .

His cruise to victory was interrupted by a chaotic sequence of events late in the race. The safety car was deployed on lap 60, and the race was eventually red-flagged on lap 68 after crashes for Lance Stroll and Charles Leclerc caused significant damage to a section of track at the final corner . This led to a delay of approximately 40 minutes for repairs .

When the race resumed for a seven-lap sprint, Antonelli handled the pressure of a standing restart with composure, quickly pulling away from Ferrari's Lewis Hamilton to win by 6.271 seconds . Red Bull's Isack Hadjar finished third, securing his second podium in Formula 1 .

Antonelli's victory was historically significant. At 19 years old, he became the youngest-ever winner of the Monaco Grand Prix, breaking a record previously held by Lewis Hamilton since 2008 . He also achieved his first grand chelem (pole position, win, fastest lap, and leading every lap) in a Formula 1 race . The result extended his lead in the Drivers' Championship to a formidable 66 points over second-placed Hamilton .
