Cadillac is ramping up its 2026 Formula 1 preparations with a test session at Imola, where Sergio Perez is driving an old Ferrari SF-23.
The two-day session gives Perez a chance to reacclimate to racing after nearly a year away from the grid. The decision to use an older Ferrari chassis stems from Cadillac’s existing engine supply deal with the team, making it a natural choice for early development work.
While Valtteri Bottas isn’t available for this test, the seat time will be valuable for Perez as he gets back into racing rhythm after almost a year away from the sport.
Perez has spoken openly about how much he was looking forward to joining Cadillac, pointing out that his desire for a new challenge played a big part in his return to F1.
Valtteri Bottas to miss Cadillac F1’s first test due to Mercedes contract
Bottas was ‘surprised’ by a recent tour of the Cadillac factory and came away impressed with how much progress the team has already made.
The new regulations mean every team will be adjusting at the same time, which should help level the playing field early on.

Perez, who joined Cadillac over the summer and isn’t tied down by any other contracts, has already been doing valuable work behind the scenes. Their first test is an important milestone for everyone involved.
It’s also a good opportunity for mechanics who haven’t been in a live race environment to get familiar with their routines and workflows.
Bottas won’t be taking part because his contract with Mercedes runs through the end of this year. That means he’ll have to wait before joining his new team on track.
Overseeing things is team manager Peter Crolla, who brings experience from his two years in a similar role at Haas between 2022 and 2024. The SF-23 they’re running is notable for its completely blank livery, making it stand out even before any official branding goes on.
Cadillac boss Graeme Lowdon explains the purpose behind Perez’s test
Cadillac have established a plan with Perez which helps to include him in a lot of their technical meetings. It’s something that will be an advantage to them down the line.
Perez’s feedback from the sessions will be valuable for a team still finding its feet, especially as they look to blend new personnel into F1 routines.

Graeme Lowdon spoke to Motorsport.com’s Italian edition about what Cadillac hopes to gain from the Imola outing, outlining their priorities.
“We’re not testing the car, we’re testing people,” he said. “The advantage we want is for our mechanics to have the same experience as those who work in the F1 pitlane every day.”
