Perez: F1 Car Upgrades Stuck in Factory Limbo

Cadillac F1 driver Sergio Perez expressed frustration over the ongoing lack of performance upgrades for his MAC-26 car. The team is struggling, having not scored any points this season. Perez revealed that essential new engine and rear wing components have been designed but are significantly delayed in manufacturing and delivery. This situation contributed to his difficulties at the Italian Grand Prix, where he noted extreme slowness on the straights.

Speaking on May 2, 2026, after the Italian Grand Prix, Perez stated that the arrival of these parts for the upcoming Spanish Grand Prix is uncertain, describing the situation as "50/50" and "a little bit of a mess." He also received a five-second penalty for a track limits infraction. Despite these challenges, Perez expressed optimism about the new team principal, Marcin Budkowski, who started two weeks prior. He believes Budkowski is pushing the team in the right direction, with significant improvements anticipated within two to three months, towards the end of the year.

Perez emphasized the impact of the missing upgrades, particularly the new rear wing and engine, which were very penalizing. He struggled with energy management and was unable to compete effectively with other cars. The driver also found the stewards' penalty confusing, related to a chicane cut during a safety car period. He anticipates seeing substantial team input and positive changes under Budkowski's leadership.
