In the week before the race, the FIA revised the rules governing pit-to-car communications following criticism from the teams in light of a penalty given to Nico Rosberg at the British Grand Prix for receiving assistance outside those allowed under the regulations; and in the aftermath of Sergio Pérez's brake failure and subsequent retirement from the Austrian Grand Prix, which Force India was particularly critical of in light of the safety implications arising from Pérez's accident.
[5] Under the revisions introduced for the Hungarian Grand Prix, a car must pit or be retired immediately if an issue arises that is deemed serious enough to warrant intervention from the team.
[6] Mixed conditions in the first qualifying session meant that a record eleven drivers failed to make the 107% time: Red Bull Racing's Max Verstappen and Daniel Ricciardo; Williams' Felipe Massa and Valtteri Bottas; Force India's Nico Hulkenberg and Sergio Pérez; Renault's Kevin Magnussen and Jolyon Palmer; Manor's Pascal Wehrlein and Rio Haryanto; and Sauber's Marcus Ericsson.
Due to the exceptional circumstances, all eleven were permitted to start the race, and the fastest five - Ricciardo, Verstappen, Hulkenberg, Bottas, and Pérez - were allowed to proceed to Q2 as normal.
Lewis Hamilton took a comfortable win ahead of his teammate Rosberg, their only challenge came from Daniel Ricciardo who did threaten but ultimately faded away before finishing in 3rd place holding off a charge from Ferrari's Sebastian Vettel.
