Toro Rosso hits back at Renault over failures

Sao Paulo : Scuderia Toro Rosso has hit back at Renault’s suggestion that its recent reliability problems have been due to how the team operating its power units.

The Italian team has suffered a string of failures in recent races, with both Pierre Gasly and Brendon Hartley taking grid penalties for Brazil and then hitting further problems right at the start of practice.

Renault Sport F1 boss Cyril Abiteboul told Autosport on Friday that “we do have a little bit of a concern about the way that our engine is operated in the Toro Rosso car”, before adding that there are “never coincidences in this sport”.

In a statement issued on Saturday morning, Toro Rosso said the problems were nothing to do with the installation or how the team is operating the engine.

“It comes as a big surprise to the team that Cyril Abiteboul has suggested to the media that the problems Toro Rosso suffers with the power unit are primarily team related, and the way in which the power unit is operated in the STR12 chassis,” read the statement.

“We would like to clarify that all the MGU-H and shaft failures Toro Rosso has recently suffered are not associated with how the team is operating or with how the power unit is integrated in the chassis.

“Nothing has been changed or altered in this installation during the 2017 season, other than cooling improvements mid-season.

“Since the summer break Toro Rosso has suffered continuous power unit related failures, and the resulting grid penalties has cost the team points and relative positions in the constructors’ championship.”

Toro Rosso is ending its Renault engine deal early to take up a Honda supply for 2018, and has loaned Carlos Sainz Jr to the works Renault team as compensation.
