Sergio Perez spies 'positive' from early Cadillac F1 issues

Sergio Perez has admitted Cadillac faced various issues as it made its first test appearance in Barcelona on Monday.

However, the 36-year-old is content with the challenges appearing early on so they can be ironed out ahead of the season-opening round in Australia.

Cadillac donned a largely black livery as it took to the circuit in Barcelona to mark its on-track debut ahead of its maiden season.

The car was driven by Perez's team-mate Valtteri Bottas in the morning, before Perez took over duties in the afternoon.

The team reportedly completed fewer than 50 laps throughout the day as Perez acknowledged that it hit various difficulties during the test.

“It's always challenging when there is a massive rule change,” Perez said. 

“To get laps in is the main objective. We are just getting some laps on the board, which was promising. 

“We had a lot of issues today, which is good. It's our first day, so it's been positive in that regard - you want all the problems to come now.

“Hopefully the next couple of days can be a lot smoother for us.”

Cadillac have two more days this week to choose from to collect further data ahead of the next two test sessions in Bahrain in February.

When asked for what Cadillac should expect for the rest of the upcoming week, Perez said: “Just trying to maximise everything. 

“Everything has been running a little bit too smoothly at the moment, just trying to get laps in which I think is going to be the priority going into the coming days.

“That will be the main thing.”
