McLaren Formula 1 drivers Fernando Alonso and Jenson Button are facing grid penalties for this weekend's Italian Grand Prix as Honda plans to fit their ninth engines of the season.
McLaren performed a double engine change at Spa to increase the number of internal combustion engines (ICEs) available for the next few races without incurring further penalties.
The rules state that a driver will take a 10-place penalty for the first change of a set of components and five places for subsequent changes to that set, once the first four of that part have been used.
It is understood Honda will not perform a double change for the second successive race, this time completing just one change, which gives each driver three relatively fresh engines that can be used without penalty.
While the move will likely confine both drivers to the back of the grid at Monza, Alonso has already said he expected a "painful" weekend due to Honda's lack of power.
The strategy puts McLaren in a stronger position ahead of the next race in Singapore, where the track characteristics provide a good opportunity for the team to score points.
