McLaren and Red Bull make aggressive moves for crunch Baku showdown

McLaren and Red Bull have arrived in Baku with extensive upgrades for the Azerbaijan Grand Prix, while Mercedes and Ferrari have brought no new parts.

Why it matters:

McLaren's eight-update package and Red Bull's five-update response show both teams pushing hard in the title fight, while Mercedes and Ferrari's silence signals confidence in their baseline.

The Details:

• McLaren's package spans the sidepod, engine cover, floor, diffuser, rear suspension, and rear wing.
• Revised sidepod inlet and engine cover improve rear flow conditioning, with an alternative sidepod shape available.
• A new floor edge and diffuser, plus modified rear suspension fairings, maximize aerodynamic gains.
• A circuit-specific rear wing change cuts drag on Baku's long main straight.
• Red Bull's package is led by revised floor and diffuser geometries targeting extra local load while maintaining flow stability.
• New sidepod junction, cooling louvres, mirror assembly, and halo fairing changes support the new floor.

The midfield battle:

Audi brought the largest midfield package — front wing, nose, floor, halo, engine cover, rear suspension, brake ducts, beam wing, and rear wing — with a new floor for consistent load increase. Williams brings five updates including a new floor and revised tail, while Racing Bulls has three changes headlined by a new front wing. Cadillac revised its brake cooling and front suspension fairings, while Aston Martin, Haas, and Alpine have no updates.

What's next:

Baku's mix of long straights and tight corners offers an immediate verdict on these upgrades. With Mercedes and Ferrari standing pat, Sunday's result could reveal whether aggressive development or stability wins out.
