Checo Pérez Confirms Electrical and Engine Changes for His Car

Sergio Pérez, the Mexican driver for Cadillac, announced that significant changes will be made to his Formula 1 car's electrical system and engine ahead of the Austrian Grand Prix.

“

If we look at the positive side, Valtteri (Bottas, his Finnish teammate) had a great session this morning. We saw some light with the new evolutions, but unfortunately, I drove very little today.

Pérez, who finished last in the practice sessions at the Red Bull Ring without setting a time, stated the modifications are intended to ensure a "clean day" on Saturday. His car stopped twice during the sessions, hindering his ability to gather data and test new evolutions.

"If we look at the positive side, Valtteri (Bottas, his Finnish teammate) had a great session this morning. We saw some light with the new evolutions, but unfortunately, I drove very little today," Pérez commented. He added, "We still don't fully understand what my problem was, so we will change the electrical part and the engine – something that, fortunately, was planned – to ensure we have a clean day tomorrow, as we still have a lot of work ahead."

Pérez, a three-time world championship runner-up, expressed optimism that the changes will help him and the team better understand their performance. "Hopefully, we can discover where we really are and have a much better day," he said on Friday at the circuit of his former team.
