Cadillac takes Sergio Pérez home for his 300th Grand Prix, starting with a Mexico City street run

Cadillac arrives in Mexico City this week with a milestone to celebrate. Sergio Pérez will start his 300th Grand Prix on Sunday at his home race, and the American team is marking it with a show run on Paseo de la Reforma, the city's grand central avenue, on Wednesday, October 28.

The show run, in US time

The team says the public exhibition starts at 10:00 local time, ahead of the team's first ever Mexico City Grand Prix. Mexico City stays six hours behind UTC, as the official race timetable notes, and US clocks are still on daylight time on Wednesday. That makes the start 12 PM Eastern, 11 AM Central, 10 AM Mountain and 9 AM Pacific. Arizona is on 9 AM that day.

Cadillac also points out that Pérez missed his home race in 2025, so this is his first Mexico City Grand Prix in two years. In the team's announcement he called reaching 300 Grands Prix "a proud milestone" in his career.

What 300 starts means

FanAmp reports that the weekend moves Pérez past Sebastian Vettel into seventh on the list of most Grand Prix starts. Pérez has spent most of those races in the midfield and at Red Bull, and now he is the senior figure at a brand new team.

He also knows what the track does to a car. "The altitude plays a massive part," he told FanAmp, pointing to the thin air's effect on cooling and grip.

Where Cadillac stands after Austin

Cadillac's first home race did not go well. The official result has Pérez finishing 19th, while Valtteri Bottas retired. Team principal Marcin Budkowski told F1i that Bottas's race ended with a suspected power unit issue, and Pérez said he was already looking ahead to his home crowd. Our Austin Cadillac story has the full weekend.

The team has yet to score a point this season, as FanAmp notes and the official standings confirm. Budkowski said before Austin that repeated brake problems had pulled resources away from car development, PlanetF1 reports. Realistic goals in Mexico are a clean weekend, a reliable finish for both cars and a strong showing in front of a crowd that will be firmly behind Pérez.

The bigger picture

Questions over the 2027 lineup have not gone away. Team principal Budkowski declined to confirm the pairing in Austin, and American reserve Colton Herta remains in the conversation. We track that in our 2027 open seats story and on the Cadillac hub.
