There is a big disadvantage to this method, as no development will be implicated on the engine. Toro Rosso are currently running with the 2015 Ferrari engine and are very clearly struggling in a straight line.
However, Nasr feels that Sauer have their best interest at heart, and know what they are doing.
“I knew they were more focused on the chassis side as that is where we are lacking the most, the platform itself of the car,” the 24-year-old said. “I knew it from the beginning. I feel there is more to gain as well.
“Putting things on the table as I said as a team, they really saw how much we can gain on the engine, how much we can gain on the chassis.
“I think there is more, if we can really focus on the aero of the car, getting a better braking performance, better traction, better corner stabilisation, there is so much more we can explore in the car. I’m quite OK with the decision.”
“I see this team on the way up and I see a lot of positives happening, a lot of good people have come on board and they are looking for more to the end of the year.
“It has really taken a step up here. I see the team forming a structure behind and in terms of development it will be totally different to this year the way we have the car and performance.”
