Formula 1's 2026 championship race has opened up with seven drivers considered genuine contenders following the introduction of new regulations. Seven hopefuls including Russell, Verstappen, Leclerc, Hamilton, Antonelli, Norris and Piastri will compete in the season-opening Australian Grand Prix March 6-8, with no clear dominant car emerging during pre-season testing.

McLaren, Mercedes, Red Bull and Ferrari form the "big four" teams at the top of the pecking order, but their positions remain uncertain. Bookmakers struggle to separate the contenders, with odds showing the top seven drivers closely grouped. The new regulations have effectively reset the field, creating unprecedented competition among title hopefuls.

Each contender faces unique challenges as the season begins. Russell seeks his first championship after dominating Hamilton and Antonelli. Verstappen remains a threat despite Red Bull's power unit transition. Hamilton and Leclerc aim to capitalize on Ferrari's improved form, while Norris and Piastri look to capitalize on McLaren's momentum from 2025.
