Toro Rosso driver Carlos Sainz Jnr somewhat let the cat out of the bag in Abu Dhabi when he was quoted as saying his Toro Rosso team will be utilizing Ferrari power in 2016. "On the one hand it is a relief that this is our last race with Renault," speaking to Spanish broadcaster Movistar "I believe we will have more power with Ferrari next year, and also better reliability. The problem for Renault was in the factory," Sainz added, "...they [Renault] just couldn’t make it work but it is the engineers here in the paddock who take the blame when in fact they are only trying to maximise what they have." With no announcement from the team forthcoming, the Spanish driver was keen to backtrack on his previous comments when tackled on the subject later in the day, "I did not say Ferrari. I did not mention that word. I only said that I hope to get a more powerful engine in the coming year,". Conventional wisdom in the paddock was for Toro Rosso to follow sister team Red Bull Racing and use unbranded Renault power next season, but this latest revelation will add an interesting talking point going into the final race of the year. It is expected that the deal with Ferrari will be for 2015-spec engines and not the new 2016 units.
