Twelve months ago, Renault's Formula 1 operation must have wished the ground could have opened and swallowed it up.
After four consecutive world championship doubles with Red Bull, it could barely string a sequence of laps together. The sight of the RB10 grinding to a halt on track (and the sound of grinders flaying bodywork in the Red Bull garage) was almost as common as seeing a Mercedes-powered F1 car crossing the line to begin another valuable pre-season lap.
In the words of team boss Christian Horner, Red Bull and Renault are in a "completely different position" with pre-season testing now in its second half.
