Audi’s sole car in Formula 1’s Miami Grand Prix sprint race has been disqualified for an engine technical infringement.

Gabriel Bortoleto finished 11th in Saturday’s race after Audi team-mate Nico Hulkenberg failed to take the start because of a mechanical failure.

Bortoleto has been disqualified though because his engine’s intake air pressure exceeded the maximum permitted limit.

Audi accepted that the FIA measured the pressure to be above 4.8barA but argued in mitigation this happened over one lap when temperatures rose higher than expected.

The team then “took steps to bring the car back in compliance” which the FIA stewards recognised but ruled the car must be in compliance at all times, and it was not.

Therefore the black-and-white stance on technical infringements was retained and Bortoleto was disqualified.

It is unclear whether the participation of either Audi in qualifying is at risk because of the technical issues from the sprint.

Hulkenberg’s issue made it the third time in five events – three grands prix and two sprint races – that an Audi driver has not been able to take the start due to engine problems.
