Mercedes' title double sets up thrilling new era of Formula 1, says Sky Sports

Mercedes have started Formula 1's latest regulatory era in dominant fashion, securing both the Drivers' and Constructors' Championships in 2026. However, the growing competitiveness of their rivals suggests the sport could be heading towards a particularly exciting period.

Kimi Antonelli made history by becoming the youngest world champion in Formula 1 after securing the Drivers' title at the Mexico City Grand Prix. One week later, Mercedes clinched the Constructors' Championship in Brazil, with three races still remaining.

The Silver Arrows won the opening six races of the season and established a substantial early advantage. However, their dominance has gradually faded as McLaren, Red Bull and Ferrari have closed the gap. Mercedes have managed only one victory in the last five races, while Lando Norris and Max Verstappen have both added three wins to their respective tallies.

Team principal Toto Wolff believes the competitive balance could make the coming seasons particularly interesting. He pointed out that modern teams have become increasingly sophisticated, making it harder for one manufacturer to maintain a significant advantage over its rivals for an extended period.

There are also important differences compared with Mercedes' previous dominant period, which began in 2014. Red Bull's new power unit operation has already demonstrated strong performance, while the FIA's additional development opportunities are designed to help manufacturers close performance gaps.

McLaren also have the potential to challenge again. Although the team struggled to extract the maximum from its Mercedes power unit during the first year of the regulations, improvements over the winter could make them stronger contenders in 2027.

Ferrari, meanwhile, have lost valuable points through strategic mistakes, qualifying difficulties and incidents between Lewis Hamilton and Charles Leclerc. Improving their execution could help the Italian team return to the title fight.

Red Bull remain another serious threat, particularly with Verstappen showing strong form towards the end of the season. Their challenge will be to begin 2027 with a more competitive car rather than having to recover lost ground during the campaign.

Mercedes may have secured both championships, but the changing competitive picture suggests their rivals are already preparing to challenge their position. With several teams showing the potential to fight at the front, the next chapter of Formula 1 could be considerably more unpredictable.
