Cadillac 'fighting issues' in Barcelona as F1 debut ticks closer

Sergio Perez has highlighted Cadillac was “fighting issues” throughout the day on Thursday when he was behind the wheel.

Cadillac's F1 car made its on-track debut on Monday with both Perez and team-mate Valtteri Bottas taking it out onto the circuit.

However, the team did not make another appearance until Thursday when Perez handled driving duties, clocking up 66 laps across the day of running.

Perez highlighted the team is improving every time it takes to the tarck, but conceded there are still problems it is trying to iron out.

“It was a much better day,” he said. “Obviously, we got a lot of running, a lot of information.

“We're still fighting a few issues out there, which is great - it was all about it today. 

“We are improving on pretty much every run.

“[There are] issues all around with the power unit, with the car, with a few electronics issues. 

“But this is great that things are happening here. We have a lot of of work ahead of us, being a new team.”

Cadillac is facing a challenging campaign ahead as it arrives as the sport's newest team, having established itself from scratch.

It employed the services of Perez and Bottas - two of F1's most experienced drivers - for its maiden season.

Perez, who last raced in 2024, said of his return: “Coming back, it felt a little bit strange, seeing some people, some drivers, again. 

“It felt like it's been a long time since I last saw them. I'm happy to be back.”
