Toro Rosso Formula 1 chief Franz Tost says there is no frustration over the power deficit of the Renault engine used by the team, citing confidence in the French manufacturer to make gains in the coming races.
Toro Rosso’s weakest area through 2016 was power after it opted to use Ferrari’s 2015-spec engines, meaning development was frozen for the entire year.
With relations between parent team Red Bull and Renault once again cordial, Toro Rosso moved back to a current-year supply for 2017, only to for there to be a power deficit compared to the Ferrari and Mercedes power units.
Toro Rosso currently sits fifth in the F1 constructors’ championship, with Carlos Sainz Jr. scoring its best result of the season so far last time out in Monaco, finishing sixth.
Renault has promised engine updates will arrive in the next few races, and Tost is pleased with the progress that is being made, even if it is gradual.
“Renault is making some small steps,” Tost said. “First of all, they have to get everything under control from the reliability side. We must not forget that Renault came up with a completely new design of an engine and this takes time.
“We all know that the power unit now is very very complicated and I’m convinced that within the second half of the season they will provide us with a very good, powerful engine. I must say that so far we are quite happy with the performance with Renault.”
While Red Bull remains frustrated by the performance of its power unit as it looks to gain ground on rivals Ferrari and Mercedes, Tost said Toro Rosso remains relaxed, particularly in light of its struggles in 2016.
“There’s no frustration. It always depends where you are coming from,” Tost said.
“Last year we had a one year-old engine and now we are even happy to have this year’s engine and as I just mentioned before, I’m convinced that Renault will do the steps forward which they promised.”
