Mercedes secured the 2026 Constructors’ Championship in Brazil on Sunday, November 8, a week after Kimi Antonelli claimed the Drivers’ Championship in Mexico. Antonelli became Formula 1’s youngest ever world champion.
The Silver Arrows began the 2026 season with dominant performances, winning the first six rounds. However, rival teams subsequently closed the performance gap.
Since Mercedes’ initial six victories, the team has secured six additional wins. McLaren’s Lando Norris and Red Bull’s Max Verstappen have each recorded three victories.
Ferrari drivers Lewis Hamilton and Charles Leclerc have each earned a single victory. Mercedes sealed their constructors’ title in São Paulo with Antonelli finishing fifth.
His teammate George Russell finished fourth, while Norris secured the race win. This result meant Mercedes had only one victory in the last five races.
This contrasts with 2014, when the introduction of hybrid power units led to eight consecutive constructors’ titles for Mercedes. That season saw Mercedes win the first six and final seven rounds.
Toto Wolff, Mercedes Team Principal, commented on the evolving competitive landscape. He stated that the sport is entering its most competitive era.
“It looks like the most maybe competitive era that is about to start because the teams have become so professional in capability and resource that these kind of runaway seasons, I don’t see them anymore.”
The 2026 regulations introduced the Additional Development and Upgrade Opportunities (ADUO) system. This measure aims to level the playing field among power unit manufacturers.
Manufacturers deemed more than two percent behind the leading power unit receive upgrade opportunities. Those more than four percent down are granted additional aid.
The FIA controversially assessed Red Bull’s new power unit as the strongest performing engine in its debut season. This assessment occurred while Mercedes was still dominant.
Red Bull Powertrains, based in Milton Keynes, is a new division. Its continued development is expected to maintain close competition in the power unit sector.
McLaren, a Mercedes customer team, faced disadvantages in 2026. Issues included gear ratios being shorter than intended, impacting performance.
The team anticipates making adjustments over the winter to optimize their Mercedes power unit. McLaren previously secured back-to-back titles in 2024 and 2025.
Ferrari experienced a power deficit throughout the year compared to other top teams. Lewis Hamilton identified eradicating this deficit as Ferrari’s primary focus for 2027.
Ferrari also suffered from operational inefficiencies. These included strategic errors, driver penalties, and on-track incidents between Hamilton and Leclerc.
A likely one-two finish in Mexico was lost due to a first-lap collision between the two Ferrari drivers. This highlights significant room for improvement in execution.
McLaren’s 2026 season was also affected by resources allocated to securing the 2025 Drivers’ Championship for Lando Norris. Team Principal Andrea Stella will focus on 2027 contention.
Red Bull has demonstrated strong development capabilities in recent years. Max Verstappen ended the previous season dominating and is on an eight-podium streak since the Italian Grand Prix.
The challenge for Red Bull is to start the 2027 season with a competitive package. Laurent Mekies, Red Bull Team Principal, noted the current unpredictability of race winners among the top four teams.
Mercedes’ relative performance decline in the second half of 2026 is linked to a major upgrade package introduced in Malaysia in early October. This package failed to deliver expected gains.
Antonelli’s victory in Austin was the only success in the five races since these new parts were implemented. This raises questions about Mercedes’ 2027 car development direction.
Wolff anticipates three or four teams will contend for the championship in 2027. He believes the outcome could go either way.
