Le coeur a ses raisons que la raison ne connaît point. 
Renault, which supplies Red Bull as well as its factory team, is believed to have the most fuel efficient engine, albeit one slightly down on power. A frugal engine will allow a team to run a lighter fuel load at the start of the race, a factor that will be worth a significant amount of lap time in the early stages of a grand prix. Fuel levels will no longer have a bearing on qualifying times, as the top ten won't have to run in Q3 with enough fuel to start the race. Therefore, the Renault powered cars may qualify lower down the grid but make significant gains during the opening laps.
