A war of words has broken out between Toro Rosso and their engine supplier Renault. Renault Sport director Cyril Abiteboul has suggested that the Italian teams engine issues recently have been down to the team and not Renault themselves.
Toro Rosso drivers Brendon Hartley and Pierre Gasly have engine penalties for Sunday’s Brazilian Grand Prix.
Toro Rosso have issued the following the following statement after free practice three:
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.
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 PU 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.
One of the primary reasons for the issues we are seeing is the lack of new power unit parts available. In Toro Rosso’s case the team is constantly having to change parts from one PU to another during the weekend and, on many occasions, is forced to run old specification assemblies.
The last race in Mexico saw only two cars out of six finish the race, highlighting the poor reliability.
We mustn’t forget that they are fighting with Toro Rosso for a better position in the Constructors’ championship, as suggested by Mr Abiteboul the situation may not be a coincidence, but it is certainly not due to STR’s car.
