FIA begins random engine checks

The FIA has begun its annual routine random checks on all Formula One engines, with Mercedes-Benz the first manufacturer whose power unit will be examined.

Formula One's current regulations feature an engine freeze, which prevents manufacturers from making technical changes over the course of the season from the specification that is lodged with the FIA at the beginning of the year.

Part of the FIA's regulatory activities includes it conducting a random test on the engines of each of the six manufacturers, to check no modifications have been made.

That process began after Hockenheim, with Lewis Hamilton's engine being the first to be sealed by the FIA so its checks can be conducted. Inspection of other manufacturers' engines will take place over the remainder of the season.

Autosport.com understand that the engine checking process has begun a little later than normal this year because the FIA has introduced some more stringent testing apparatus into the procedure.
