Daniel Ricciardo will start the Turkish Grand Prix from the back of the Istanbul Park grid after McLaren decided to take on three new power unit elements.
Ricciardo suffered a poor qualifying as he was knocked out in Q1 and was due to line up 15th given Ferrari driver Carlos Sainz's own PU penalty that had dropped him to rear of the pack.
Following qualifying, McLaren team boss Andreas Seidl had suggested the likelihood of the Australian driver taking a fourth PU of the season, with only three allowed under the FIA technical regulations.
The FIA has confirmed Ricciardo's MCL35M now has a new engine, turbocharger and MGU-H.
It means Ricciardo will start from 20th, with Sainz one place ahead in 19th.
