Italy marks the 14th round of the 21-race Formula 1 calendar and therefore two-thirds of the season will have been done and dusted by late-Sunday, so we thought it'd be time to take a detailed look at what power unit components each driver has used so far.
As per the rules, the Internal Combustion Engine (ICE), Turbo-charger (TC) and Motor Generator Unit-Heat (MGU-H) are limited to three per car per season, whilst the Motor Generator Unit-Kinetic (MGU-K), Energy Store (ES) and Control Electronics (CE) are limited to just two.
Almost every driver find themselves on their final component bar Kimi Raikkonen, who is only on his second of three MGU-Hs, and Max Verstappen, who has an ICE and MGU-H remaining penalty free.
The two Toro Rosso-Honda powered cars find themselves in the worst position having already used far more than their allocation of every component.
