For the 2007 season Rennie was placed in the same role, this time with Finnish driver Heikki Kovalainen, who arrived at Renault after the departure of Alonso.
Renault's year was dominated by the Crashgate scandal, where they were accused, and found guilty, of fixing the race in Singapore the previous season.
