Formula 1 fans around the world were left speechless after a series of unexpected, secrecy-drenched events unfolded at the historic Imola circuit — and at the center of it all was none other than Sergio “Checo” Perez, driving a stealthy black Ferrari that nobody saw coming.

The motorsport world is still buzzing:
Why was Perez in a Ferrari?
Why were Cadillac engineers everywhere?
And why was everything done behind closed doors?
Because this wasn’t just a test.
This was a message.

Cadillac, preparing for its explosive Formula 1 debut in 2026, pulled off one of the most unexpected power plays in recent F1 history: using an actual Ferrari chassis and engine for a covert two-day integration run.
While fans assumed Cadillac would quietly build their program in the shadows, they instead arrived with 20 crew members, stepped into Ferrari territory, and essentially borrowed Maranello’s muscle to fast-track their entry into the sport. Ferrari’s own staff were reportedly stunned by Cadillac’s bold, almost aggressive approach — but the partnership was already sealed.

And then came the twist:
Sergio Perez, freshly separated from Red Bull and desperate to prove his worth, climbed into a matte-black, unbranded Ferrari. No logos, no colors, nothing to identify it — a ghost car built for secrecy.
Across two intense days, Perez completed 190 laps, pushing both the machinery and Cadillac’s rookie crew to their limits. Witnesses described the atmosphere as “historic,” “tense,” and “something straight out of a spy movie.”
Then came the shock no one expected:
Perez set a blistering 1:18.82, nearly a full second quicker than Charles Leclerc’s 2022 benchmark under similar conditions.
A driver dismissed by Red Bull had just outpaced Ferrari’s golden boy — in Ferrari equipment, at Ferrari’s track.
Inside the paddock, murmurs spread like wildfire:
“Did Ferrari just expose their real pace by accident?”
“Is Checo the secret weapon Cadillac needed?”
“This test wasn’t just a test…”

Meanwhile, inside the garage, tension reached boiling point. Cadillac engineers tried to understand Ferrari systems on the fly, Ferrari mechanics monitored every move, and Perez delivered feedback so direct it reportedly left both sides surprised. At one point, the atmosphere grew so heavy that team principal Graeme Loden stated:
“We’re not testing the car. We’re testing the people.”
Cadillac’s plan is now clear:
They’re not entering Formula 1 like a regular new team.
They’re entering like a storm.

Their partnership with Ferrari gives them access to proven engines, suspension, gearbox, and core architecture for three full seasons — giving Cadillac a massive head start while they prepare their own engine package for 2029.
With Perez showing pace, Cadillac showing organization, and Ferrari providing hardware, Imola became the spark of something much bigger than a private test session.
What was supposed to be a quiet technical exercise turned into a global statement:
Cadillac isn’t coming to learn.
They’re coming to fight.
And if this was just the beginning, the 2026 grid is about to become a battlefield.
