Cadillac F1 Car Build: Inside the First Testing Push | 2026 Season

Cadillac’s Formula 1 Push: From Dynamometer to Silverstone

The Cadillac Formula 1® Team is rapidly progressing toward its 2026 debut, navigating the complex challenges of building a competitive car from the ground up. A recent glimpse behind the scenes, documented in Episode 6 of the “What Makes Fast” docuseries, reveals the intense effort and meticulous precision required to bring the team’s first Formula 1 car to life.

The initial focus centered on building a car specifically for dynamometer testing – a crucial step in validating the design and performance before hitting the racetrack. The dyno, as it’s commonly called within the team, allows engineers to simulate driving conditions in a controlled laboratory environment. This process is vital for identifying and addressing potential issues before valuable track time is lost.

“It’s a chance to make sure the car works as it should, so the team can be certain that when they get to the racetrack, drivers Valtteri Bottas and Sergio Pérez can put in laps,” according to the GM News report detailing the process.

The project wasn’t without its hurdles. A key challenge involved the logistical complexities of shipping components from various locations, including a critical dyno facility in Italy. Adding to the pressure, the team proactively accelerated its schedule by a week to maximize testing opportunities. This decision, while strategically beneficial, necessitated a swift turnaround in delivering thousands of parts to the factory for assembly.

The assembly process itself is far from routine. The report highlights the extraordinary precision required, with even minor discrepancies – measured in tenths of a millimeter – potentially causing significant problems. Every component, including the smallest fasteners, is meticulously serialized for traceability, ensuring accountability and facilitating detailed analysis.

Cadillac Formula 1® Team Chief Mechanic Nathan Divey underscored the inherent complexities of building a prototype racing car. “Every single racing car never goes together smoothly,” Divey stated. “They’re all prototypes, really. The tolerances you’re looking at are so fine… it can take such a small amount to create an issue.”

Beyond the technical challenges, team leadership recognizes the importance of fostering a resilient and adaptable team culture. Dan Towriss, Cadillac Formula 1® Team Holdings CEO, emphasized the need to prepare the team for the inevitable adversity that comes with competing at the highest level of motorsport. “It’s on me, it’s on Graeme [Lowdon, Cadillac Formula 1® Team principal] to make sure that we’re leading people to a place that we learn how to deal with adversity,” Towriss explained. “It’s going to get a whole lot harder when we’re on the grid, and we have the microscope of Formula 1® down.”

Despite these challenges, the team successfully overcame the obstacles. Shortly after the filming of the docuseries episode, the Cadillac Formula 1® car was fired up for the first time. This milestone was followed by even more significant progress on January 16th, when Sergio Pérez completed the car’s initial testing miles at Silverstone Circuit.

The successful Silverstone test marked a pivotal moment for the team, transitioning the project from the laboratory environment of the dyno to the demanding realities of the racetrack. This initial track running provided valuable data and insights, allowing engineers to refine the car’s setup and performance characteristics.

The team’s rapid progress underscores the significant investment and commitment General Motors has made to its Formula 1 endeavor. The Cadillac program represents a return to the pinnacle of motorsport for the American manufacturer, aiming to compete against established racing giants like Ferrari, Mercedes, and Red Bull Racing.

While the 2026 season remains several months away, the Cadillac Formula 1® Team is already demonstrating a clear focus on meticulous preparation and a proactive approach to problem-solving. The challenges encountered during the car’s initial build and testing phases are viewed as valuable learning experiences, shaping the team’s strategy and strengthening its resolve as it prepares for its highly anticipated debut.

The team’s early testing results and the insights gained from the dynamometer and Silverstone runs will undoubtedly play a crucial role in shaping the car’s development throughout the remainder of 2026. As the season approaches, the Cadillac Formula 1® Team will continue to refine its design, optimize its performance, and build a competitive package capable of challenging the established order in Formula 1®.

PlanetF1 reported that Cadillac has revealed its goals for the 2026 season, anticipating an aerodynamic deficit at the Australian Grand Prix. This acknowledgement of potential early challenges demonstrates a realistic assessment of the team’s position as a newcomer to the sport and a commitment to continuous improvement.

The striking new livery, recently showcased during testing in Bahrain, further signals Cadillac’s arrival on the Formula 1® stage. GPblog noted the visual impact of the car’s design, highlighting the team’s attention to detail and its desire to make a bold statement.

As ESPN points out, much remains unknown about the specifics of the 2026 Formula 1® season, but the Cadillac Formula 1® Team is clearly laying the groundwork for a successful and competitive future. The team’s dedication to innovation, meticulous preparation, and a resilient team culture positions it as a force to be reckoned with in the years to come.
