Daniil Kvyat has become the first driver to fall foul of this season’s limit of five engines per driver.
Like many of the Renault-powered runners, Kvyat has had hit hard by engine issues throughout the season.
Those problems finally caught up with him in Italy as his Toro Rosso team put a sixth engine into his STR on Friday night.
As a result Kvyat will be hit with a ten-place grid drop for Sunday’s Italian GP.
A statement issued by the FIA race stewards said: “The internal combustion engine used by the above driver is the sixth new internal combustion engine for the 2014 championship season and as this is not in conformity with Article 28.4a of the 2014 Formula 1 sporting regulations, I am referring this matter to the stewards for their consideration.”
