Allison: Ferrari, Not McLaren, Is Mercedes' True Championship Threat

Mercedes technical director James Allison says Ferrari, not reigning champion McLaren, poses the biggest threat to the team's title hopes after the Scuderia beat Mercedes outright at Barcelona.

Why it matters:

Mercedes built a commanding early lead through Andrea Kimi Antonelli's five-race winning streak, but Ferrari's aggressive development under the young regulations has quickly closed the gap. Allison cautioned that standing still is fatal under these fresh rules, and with Ferrari poised to introduce engine concessions, the championship may tighten significantly.

The details:

• Allison downplayed a McLaren resurgence, pointing out that outside Oscar Piastri's near-miss at Suzuka, the defending champions haven't fought for wins.
• Ferrari's Barcelona package featured a new front wing, floor, and diffuser to improve airflow and downforce, giving Lewis Hamilton his first victory for the team.
• Allison noted the 2026 rules are so young that a single major upgrade can deliver gains equal to Mercedes' entire launch advantage.
• Ferrari has two ADUO homologation tokens for its ICE, with the first potentially arriving at the Austrian Grand Prix to close the engine gap.
• Reliability failures for Antonelli and George Russell have already kept the standings closer than Mercedes would like.

What's next:

Mercedes is readying its own counter-upgrade, though timing depends on factory readiness. If Ferrari combines its aero gains with a power unit step in Austria, the constructors' battle could become a genuine scrap rather than a procession. With reliability woes still hurting the ledger, Allison knows the remaining two-thirds of the season demand relentless development.
