Aston Martin technical boss Adrian Newey believes a major car revamp for the Hungarian Grand Prix can persuade Fernando Alonso to extend his Formula 1 career into 2027. The 44-year-old Spaniard's future hangs in the balance as he weighs whether the Silverstone outfit can deliver the progress he demands.

Aston Martin has slumped to the back of the grid this season, their 2026 challenger plagued by excess weight and underdevelopment. Combined with Honda's uncompetitive power unit, the team has fallen behind even newcomer Cadillac in recent weeks. Alonso wants clear evidence of improvement before deciding whether to continue racing.

Newey's upgrade package centers on aerodynamic revamp and significant weight reduction, targeting the minimum weight limit. The core chassis and gearbox architecture remain unchanged, but re-homologation work has enabled substantial mass savings. New front and rear aerodynamic surfaces complete the overhaul.

The technical chief admits simulation tools lack sophistication to predict exact gains, but insists the changes represent a 'large step' forward. Alonso's experience and development guidance remain invaluable assets, yet his commitment hinges entirely on whether Aston Martin demonstrates decisive progress this summer.
