Aston Martin races to prepare two upgraded AMR26 cars for Hungary despite limited spare parts.

The revised car will feature changes to its rear suspension, nose and aerodynamic surfaces, alongside work to reduce weight. Aston Martin hopes the package can move it away from the back of the grid.

Mike Krack expects two cars to be ready but said the team may lack extensive spares. Contingency plans would allow alternative components to be used if individual new parts miss production deadlines.
