Cadillac steps up its development push ahead of the Canadian Grand Prix
After introducing its first major upgrade package of the season in Miami, Cadillac arrives in Montreal with another substantial round of developments for the MAC-26. The American team continues to evolve its Formula 1 challenger at an aggressive pace, driven by a clear objective: avoid losing ground in the direct fight with Aston Martin and move away from the most vulnerable end of the championship standings.
With another Sprint weekend on the calendar, the Canadian Grand Prix becomes a crucial test of whether Cadillac’s recent momentum is genuine and sustainable.
A second major upgrade package in just two races
Miami marked Cadillac’s first real development step of the season. Montreal now brings the second, with a significantly expanded package.
The team is introducing a revised front wing, a new floor, an updated diffuser, modified rear suspension, redesigned front brake drums, fresh diffuser detailing, additional aerodynamic wing elements and revised front torsion bars. It is an extensive intervention that goes far beyond minor refinements, signalling a team pushing hard to unlock immediate gains rather than waiting for the traditional mid-season upgrade phase.
Sergio Perez made that urgency clear after the Miami weekend, stressing that Cadillac cannot afford to stand still while Aston Martin prepares its own performance step forward.
“We are in a real hurry to improve performance because we know Aston will improve, and we do not want to be left behind,” he explained.
The Miami weekend, where Cadillac showed much more encouraging pace from Friday onwards, helped create a stronger sense of confidence inside the team. The updates appeared to deliver the expected benefits, changing the internal mood significantly.
Now the challenge is taking the next step — refining the current package, connecting all the elements and transforming encouraging signs into consistent performance.
“If we can do that, I believe we will get closer to the leading group,” Perez added.
Montreal becomes the real momentum test
On paper, Cadillac remains tenth in the championship, sitting ahead of Aston Martin only thanks to Valtteri Bottas’ 13th-place finish in China. Internally, however, the feeling is far more optimistic. The team believes it has entered a genuine upward development phase.
Team principal Graeme Lowdon reinforced that belief by highlighting not only the success of the Miami upgrades, but also Cadillac’s operational progress. The team completed both the Sprint and Grand Prix without issues and delivered two pit stops that ranked among the ten fastest of the weekend — a sign of improvement not only in technical performance, but in race execution as well.
Montreal, however, presents a completely different challenge. The Circuit Gilles Villeneuve places far greater emphasis on stop-and-go performance, traction, braking stability and mechanical sensitivity. That makes it the perfect venue to determine whether Cadillac’s recent progress is truly repeatable — or whether Miami was simply a one-off.
“The goal is to build on this momentum and continue making similar progress,” Lowdon said.
That sounds like a clear internal philosophy: no dramatic revolutions, just consistent progress. But that consistency now needs to become visible in real results.
Cadillac heads to Montreal with a major upgrade package, fresh confidence and increasing pressure. The challenge is simple: turn technical progress into points. Canada will reveal whether the MAC-26 is finally beginning to find its true direction.
Cadillac’s aggressive back-to-back upgrade strategy demonstrates a young team fully prepared to out-engineer its direct rivals in the lower midfield. By bringing such an extensive inventory of components to the limiting confines of a Canadian Sprint weekend, the squad is taking a calculated risk that its virtual design loops are completely accurate. With Sergio Perez pushing the limits behind the wheel and Graeme Lowdon refining trackside execution, the MAC-26 has an immediate opportunity to bridge the gap to the established midfield. If this latest technical package handles Montreal’s brutal kerbs and heavy braking zones effectively, Cadillac will not only secure its position ahead of Aston Martin but will firmly establish itself as a rising technical force for the remainder of the 2026 campaign.
