The 2026 Japanese Grand Prix arrives at Suzuka with major questions across the F1 2026 season as Mercedes leads while rivals struggle to respond.

The 2026 Japanese Grand Prix marks the first true stress test of the F1 2026 season. After two races dominated by Mercedes, Formula 1 heads into the 2026 Japanese Grand Prix at Suzuka with a competitive order that remains unstable beneath the surface. Suzuka’s high-speed layout will expose whether early trends are real — or fragile.

At Mercedes, the spotlight is no longer just on George Russell. Kimi Antonelli has already disrupted expectations after claiming his maiden victory in China. The Italian showed calm control in tire management and race pace, raising a critical question ahead of the 2026 Japanese Grand Prix: is this now a genuine title fight inside Mercedes?

Ferrari enters the 2026 Japanese Grand Prix weekend with clear pace but poor execution. Both Charles Leclerc and Lewis Hamilton have shown they can challenge for the lead, but strategic errors under the virtual safety car (a race neutralization phase where cars slow without stopping) and inconsistent race pace have cost results. The SF-26 is strong in high-speed corners — a key advantage at Suzuka — but converting that into points is now essential in the F1 2026 season.

The most serious concerns ahead of the 2026 Japanese Grand Prix surround Red Bull. Max Verstappen described the RB22 bluntly: “The car is completely undriveable. I cannot even put a bit of a reference in. Every lap is like survival.” A major issue lies in race starts. With the removal of the MGU-H (the turbo-linked energy recovery system), drivers must hold high revs before launch, a process that has already cost Verstappen multiple positions this season.

McLaren also arrives at the 2026 Japanese Grand Prix under pressure. Oscar Piastri has yet to start a race this year due to incidents and a failed fire-up (the pre-race engine ignition sequence before the formation lap), while Lando Norris has struggled with reliability. Suzuka represents a critical reset moment.

Audi completes the list of key unknowns heading into the 2026 Japanese Grand Prix. Despite promising early pace, the resignation of Jonathan Wheatley as team principal has created instability. Under Mattia Binotto, the team must now prove it can maintain its trajectory in the F1 2026 season.

The 2026 Japanese Grand Prix is not just another race — it is the first moment the F1 2026 season begins to reveal its true competitive order.
