Jenson Button is set for a drive through penalty for the second successive race after being handed a 25 place grid penalty for the Austrian Grand Prix.
McLaren has fitted a sixth turbocharger to his car, leading to an initial 10 place grid drop.
The use of a sixth MGU-K, fifth ICE and fifth MGU-K each comes with a five place penalty, leading to an overall total of 25.
As it will be impossible for Button to serve his full grid drop, he will face a time penalty - or more likely a drive through - in the race.
Team-mate Fernando Alonso is also set to be affected by a drive through penalty, as he has a 20 place drop.
Button also faced a hefty penalty in Canada, as he had to serve a drive through penalty in the race after being unable to fulfil a 15 place drop.
