The switch back to the Renault engine will give Toro Rosso a boost next season, that is according to lead driver Carlos Sainz.
Amid the Red Bull dissemination with Renault last year, Toro Rosso went off in their own direction securing a year-old supply of the Ferrari powertrain, while the main Red Bull re-badged their Renault engine TAG Heuer.
As Renault have invested in the sport heavily, taking back control of the Lotus team as their own works outfit, gains have been found and Red Bull are happy with the direction of development.
Sainz, who at times has outperformed the car this season believes the technical team combined with the Renault engine next season will bring further gains in performance, “I think Toro Rosso is in constant progress at the moment. Obviously this year we have been a bit hampered by this power deficit that you all know by now. But if you look at the car and how it was performing in Austin, it’s a pretty decent car I must say.
“I really enjoy driving it. So as James Key and his team they do a very similar job to this last couple of years and the Renault engine works well, I think Toro Rosso has a good line-up next year to exploit this full potential of the car with Dany and myself and I really think we can move a bit forward in the Constructors’ Championship.
“We have the right people on board and we just need a bit of straight line speed, a bit more things coming together to put together some stronger results.”
