Lewis Hamilton's grid penalty for the Belgian Grand Prix has increased to 55 places following a third power unit change on Saturday morning.
In a bid to maximise the number of components Hamilton has available for the rest of the season, Mercedes has opted to deliver three new power units this weekend.
Two were fitted on Friday – earning Hamilton a 30-place grid penalty – while further changes were made ahead of final free practice.
Hamilton was given his sixth internal combustion engine, his sixth MGU-K, an eighth MGU-H and an eighth turbocharger. These have added a further 25-place drop.
The penalties will ensure that Hamilton starts from the back of the grid, and it is thus unlikely that the Brit will do many laps in qualifying because it will be beneficial for him to save tyres for the race.
