Rubens Barrichello will on Sunday join his Honda teammate at the back of the Turkish grand prix grid.
Jenson Button’s 2.4-litre V8 power plant had to be changed after a problem developed during Istanbul qualifying on Saturday.
It now emerges from the scene of the race on Sunday that Barrichello, driving an identical RA107 single seater, must also move back ten places because of an engine change.
The Brazilian will, however, still line up in front of Button on the last row, after out-qualifying Button by a few hundredths for fourteenth quickest in Q2.
