Ahead of Saturday's qualifying for the Austrian GP, both Jenson Button and Fernando Alonso are sitting on 25-place grid penalties each.
Forced to change several elements of Button's Honda power unit, the Brit's tally has now reached 25.
He will drop 10 places for a sixth turbo, five for a fifth ICE, another five for a sixth MGU-H and finally a further five for using a fifth MGU-K.
As a result, Button is likely to face a drive-through or even a stop-go penalty.
Meanwhile Alonso's penalty tally also reached 25 in final practice as McLaren were forced to change his gearbox.
