The tight clustering around 50% for Mercedes, Ferrari, McLaren, Red Bull, Alpine, and Racing Bulls reflects shifting form under the 2026 regulations and recent upgrade cycles. Mercedes has secured 11 poles through 17 rounds but faces closing gaps from Ferrari's engine and aero gains plus Red Bull's strong late-season pace that delivered multiple victories. McLaren's inconsistent qualifying and Red Bull's turnaround have created a multi-team battle for ultimate one-lap speed at Interlagos, where track characteristics and setup tweaks can alter the order quickly. Lower-placed squads like Aston Martin and Williams trail due to smaller development steps, keeping the constructor pole market highly contested heading into the São Paulo weekend.
