The 
Italian Grand Prix is scheduled for this weekend. The Monza circuit is known as a track where overtaking is fairly easy, which is why teams often choose to take a grid penalty here in exchange for a lot of new engine parts. Here is an overview of the used engine parts of all drivers after 
Zandvoort.
Magnussen and Zhou with new parts at Zandvoort
The 
Dutch Grand Prix will be held at 
Circuit Zandvoort, which is a circuit where engine power is not very important. Therefore, teams often do not choose to put new engine parts on such a track, as it simply does not save that much time here. Taking a grid penalty for new engine parts at 
Zandvoort is also not practical, because of the limited overtaking opportunities.
Kevin Magnussen, along with 
Guanyu Zhou, was the only driver who did get new parts at Zandvoort. This was not decided for Magnussen until the day of the race. Partly because of this, the Dane started from the pit lane, which had little impact as Magnussen had qualified 18th. Zhou got away with no penalties as the Chinese changed to the last of his four permitted ICE, TC, MGU-H and MGU-K.
 Overview of engine parts used after Zandvoort
In contrast to Zandvoort, the Monza circuit in Italy is a track where a new engine can save a lot of time and overtaking is also a lot easier. Will we therefore see many drivers taking a 'tactical' grid penalty in Monza, just like in previous years?
