McLaren has will use to its old, longer nose at the Italian Grand Prix as well as a fresh pair of engines that will result in more grid penalties for both drivers.
McLaren started the year with a long nose before introducing a shorter version on Fernando Alonso's car at the Austrian Grand Prix. However, as part of its low-drag package for the Italian Grand Prix it will run the longer nose as a one-off this weekend.
Both drivers will be hit with grid penalties for engine changes at Monza, just one race after a combined 105-place grid penalty at the Belgian Grand Prix. The two cars will be fitted with another internal combustion engine this weekend, which will be the ninth for both. Jenson Button will get a five-place grid penalty as he has already used a ninth turbocharger and MGU-H, while Fernando Alonso will get a ten-place penalty as he has yet to use a ninth of any of the listed components that incur penalties.
McLaren is expecting another weekend at the bottom of the timesheets at Monza, so it makes sense to take the penalty now and add the extra engines to its pool for the rest of the season when it is hoping to be more competitive and will suffer more from a drop down the grid.
