The quiet, historic curves of the Autodromo Internazionale Enzo e Dino Ferrari in Imola recently hosted a secret that has already begun to ripple through the competitive landscape of Formula 1. What was intended as a routine operational learning session for Cadillac, the American outfit preparing for its 2026 grid debut, transformed overnight into an electrifying statement of intent. At the heart of this transformation was Sergio Perez, whose performance behind the wheel of a two-year-old Ferrari SF-23 was not just fast, but genuinely shocking, serving as a profound ‘reset’ for his career and an unexpected shot of confidence for his future team.

Cadillac is not just entering Formula 1; they are entering a brutal, unforgiving sport dominated by giants. Assembling a structure piece by piece, recruiting engineers, and building departments from the ground up, they are preparing to be the smallest team on the grid in 2026. This is precisely why the two-day test at Imola was so critically important. It was not merely a public relations exercise, nor a simple tire shakedown. It was a baptism by fire, a precious window into what the team could become, facilitated by the rare generosity of Ferrari, who opened their elite F1 operations to their future rival. The partnership to allow Cadillac access to the SF-23 was an unusual arrangement, but the dividends, delivered spectacularly by Perez, were instant and immense.

The Calm Before the Storm: Perez’s Personal Reset

The test’s emotional narrative began with Sergio Perez. After the highly publicized, and often painful, emotional conclusion to his time at Red Bull, where his performance was constantly measured against the singular brilliance of Max Verstappen, Perez arrived at Imola with a strikingly different, noticeably calmer energy. For the first time in years, he stepped into an F1 car without the immense, suffocating shadow of pressure and internal politics. This test represented a clean slate, a return to the purest form of his talent: just a driver and a machine, focusing on the basics of high-performance driving.

From his installation lap, it was immediately clear that this was no gentle reintroduction. Perez settled into a rhythm with the SF-23, attacking the curbs, pushing the braking zones, and treating the session like a true opportunity, not a procedural task. His early pace was a surprise even to the veteran Ferrari engineers overseeing the Cadillac program. They had anticipated a cautious beginning, given that Perez had not been in an F1 cockpit for months. Instead, his confidence grew rapidly. The connection between the driver and the car looked effortless, as if he was rediscovering a vital part of his driving self that had been compromised during the final, fraught months at Red Bull. The mood on the pit wall quickly shifted from curiosity and logistical focus to genuine intrigue and excitement.

Cadillac’s Operational Masterclass: Learning From the Masters

While Perez was setting the track alight, the primary, non-lap-time objective for Cadillac’s nascent team was being executed with ruthless efficiency. Ferrari spent the duration of the test acting as operational mentors, bringing Cadillac’s engineers deep into the meticulous world of Formula 1 operations. The lessons were invaluable, beginning with the highly synchronized art of the pit stop.

Cadillac engineers stood mere meters away as Ferrari mechanics demonstrated the full, precise choreography: the timing of the wheel guns, the synchronized movements, and the relentless discipline required to achieve the holy grail of a sub-three-second stop. What appears simple from the grandstands is, in reality, a precisely engineered, high-pressure routine.

The second major pillar of learning centered on tire preparation. Ferrari painstakingly detailed how temperature, pressure, timing, and even minor environmental factors critically influence the tire’s operating window. For a new team, this intimate knowledge is vital to avoiding the costly, race-ruining mistakes that can plague even established teams. Ferrari treated the test almost like a miniature race weekend, with Arthur Leclerc running the car the previous day to provide a baseline reference model. Cadillac absorbed everything: warm-up routines, out-lap procedures, pit entry habits, and the complexities of real-time data analysis.

This insight is invaluable for a team like Cadillac. While they may not have the sheer manpower and infrastructure of a Ferrari or a Mercedes, the opportunity to learn directly from a top team allows them to build smarter, leaner, and more efficient internal structures. It turns theoretical planning into practical, observed knowledge.

The Lap Time That Halted the Garage

The test became truly extraordinary, however, when the focus shifted to the raw data—specifically, Perez’s lap times. On the first day, he completed an astonishing 99 laps, easily exceeding the distance of a full Grand Prix, with a fastest time of 1 minute 18.82 seconds.

But the second day is where the narrative exploded. Under conditions engineered to be conservative—hard tires, a significant amount of fuel in the car, and non-aggressive engine modes—Perez delivered a remarkable lap of 1 minute 17.270 seconds.

The time was a shockwave. It was quicker than anyone in the garage, on either the Cadillac or Ferrari side, had expected. It was a time that placed him remarkably close to Ferrari’s own reference data under those specific conditions, an unexpected feat for a driver stepping into the machinery for the first time. Experienced Ferrari personnel quietly acknowledged that this level of immediate pace was simply not typical.

For Cadillac, this was not just a fast lap; it was the strongest possible confirmation that their lead driver is entering the 2026 season in supreme form. The data validated a clean, controlled driving style, showing stable tire wear on long runs and consistent, high-quality feedback.

Validation, Focus, and the Future

For Sergio Perez, the fast lap represented far more than a number on a screen. After years of relentless criticism and the constant burden of comparison, this was a powerful, tangible opportunity to show that his driving instincts, speed, and precision remain completely intact. Engineers noted the palpable difference in his demeanor—how relaxed he seemed between runs and how eager he was to continue driving. Completing 184 laps over two days, the equivalent of three full race distances, physically and mentally proved that his fitness, focus, and motivation are precisely where they need to be for this next, crucial chapter of his career.

For Cadillac, the test moved beyond being merely “useful” to becoming reassuring. They now understand, more clearly than any simulation could provide, what Formula 1 truly demands:

How quickly tire conditions can shift.

How strategy must adapt in real-time.

The critical nature of communication when dealing with modern hybrid systems.

The ferocious pace at which high-stakes decisions must be made.

These are lessons that no amount of simulator time can fully replicate. For a team planning to be the smallest on the grid, every single detail matters, and the operational insights gained will allow them to build smarter, more efficient processes.

The Imola test was an unprecedented opportunity for both driver and team. Perez has found his focus and quiet confidence, shedding the internal noise that plagued his final years at Red Bull. Cadillac, meanwhile, has gained an invaluable foundation, transforming the natural uncertainty of a debut into the strong, pragmatic reassurance that their structure, their operational procedures, and, most crucially, their star driver, are ready to compete at the highest level come 2026. The fastest lap was simply the proof: the smallest team on the grid is now armed with the confidence of a front-runner.
