Pierre Gasly is set to join Daniel Ricciardo on the back row of the German GP grid after Honda opted to change most of his power unit components for the race.
The decision was made to add more elements to his engine pool at a race where the penalty would be relatively low.
Gasly was only 16th on the provisional grid, and he now drops to 20th behind team-mate Brendon Hartley, Lance Stroll, Stoffel Vandoorne and Ricciardo.
Under the current rules the order for anyone with more than 15 places the grid position is determined by the order in which the offences were committed, and Ricciardo was first, which is why Gasly drops behind him.
Honda explained: "Prior to today's race, for tactical reasons, we are changing all PU elements with the exception of battery-related components on Pierre's car."
FIA documents confirm that he has changed all six elements, so he has a new V6, turbo, MGU-H, MGU-K, energy store and control electronics.
Hartley took a raft of new Honda elements at Silverstone, so the move ensures both men have plenty of leeway heading to Hungary, a race which could present an opportunity for Toro Rosso due to the twisty circuit layout.
