Renault F1 director Jean François Caubet claim that they are supplying high fuel efficient engines for F1, but the same time they admit their engine not have the most powerful engine in Formula 1.
Renault done excelled job in last some seasons, winning back-to-back World Title doubles with Red Bull Racing in 2010 and 2011.
Renault F1 director Jean François Caubet says that, part of the top secret to that achievement in their engine’s fuel efficiency.
“The Mercedes engine is about 15hp more power than ours, so too does Ferrari offer more power,” he told AS and PlanetF1 reports.
“But, as far as drivability and fuel economy go the Renault engine is out in front as we need less gas.”
In fact, so much so that Caubet estimates that Red Bull Racing, the defending Champs, “can start races with 15 or 18 litres less fuel in the tank than their competition – and that makes the difference.”
