With the increased focus on reliability and durability in 2014, keeping an eye on the number of power unit components throughout the season could prove key to any championship hopes.
Should a driver exceed the allocation of any of the components below – of which they get five per season – then they will be hit with a grid penalty.
Should a driver use a sixth component for the first time, they will be hit with a ten-place grid penalty. A five-place penalty will be applied to any sixth component after that and so on.
Here are the latest statistics concerning use ahead of the Monaco Grand Prix.
ICE – Internal Combustion Engine
