After a chaotic sprint weekend, Audi encountered further power-unit and technical problems during the main Miami Grand Prix, affecting both drivers once again.
Nico Hulkenberg missed the sprint after a power-unit failure and fire on the way to the grid, then retired from the grand prix after seven laps with an overheating drivetrain following a collision. Gabriel Bortoleto was disqualified from the sprint for exceeding the engine intake air pressure limit but recovered to finish 12th in the race despite earlier brake problems. The back-to-back incidents underscore ongoing reliability challenges for the Audi-powered squad.
