F1TECH: How did Red Bull upgrade its RB22 at Montreal?
Red Bull continued its steady, methodical development push in Montréal, adding a second wave of refinements to the RB22 after the larger upgrade package introduced in Miami.
While Miami delivered structural aerodynamic changes, the Canadian Grand Prix brought targeted, circuit specific and flow sensitive updates — particularly to the front wing, front corner cooling, floor, and engine cover.
Together, these updates reflect Red Bull’s attempt to stabilise the RB22’s operating window and claw back performance in a season where Mercedes and McLaren have set a fierce development pace.
Front Wing — Balance Range Red Bull introduced revised flap elements on the second and third elements of the front wing. The team explained: “Both second and third front wing elements forming the flap assemblies are revised to shift the aerobalance range available for the upcoming circuits.” This was a classic mid season refinement. Red Bull is adjusting the aerodynamic balance window, giving drivers more flexibility to tune the front end response for circuits with heavy braking zones and slow speed rotation — both key characteristics of Montréal. It suggests the team is still searching for a more predictable front end platform after early season inconsistency. Red Bull brought a revised brake duct exit geometry, specifically for Canada and Monaco. The Milton Keynes-based outfit described: “The next two circuits on the calendar demand more brake assembly cooling and to offer this an enlarged exit duct has been produced to enhance the cooling.” Even if Montreal is not as notoriously hard as on brakes as it used to be in the past according to Brembo, the Il Notre Dame track still required a lot from the brakes. Red Bull’s enlarged exit duct increases mass flow through the brake assembly, reducing the risk of overheating and ensuring consistent braking performance. This is a reliability driven update, but it also stabilises tyre temperatures — a known weakness for Red Bull this season. The RB22 received updates to the bib edge trim and forward floor devices. “To further optimise both the bib and forward floor devices, the former has a trim applied and the latter mildly increased camber resulting in the local load increasing.” This tweak was the most performance relevant part of the package. The bib and forward floor region are critical for sealing the floor and feeding the diffuser. Increasing camber and refining the trim improves local pressure distribution, generating more consistent downforce and reducing separation at low ride heights. This should help Red Bull in traction zones and improve rear stability — areas where McLaren and Mercedes have recently gained ground. A circuit specific cooling exit panel was introduced. Given the cooler conditions in Montreal compared to Miami, “a closed radiator exit panel has been created with the louvre steps necessary for the race in Miami now closed.” This was a cooling efficiency trade off. Miami required aggressive louvres due to extreme heat; Montréal did not. Closing the radiator exit panel reduces drag and improves rear end flow quality, helping the RB22 regain some straight line efficiency without compromising thermal stability.
