Toro Rosso have hit back at claims from Renault that the recent spate of engine failures could be down to the team, strongly hinting that more than just bad luck could be to blame... With Toro Rosso locked in a fierce fight with the works Renault Sport team for sixth place in the constructors championship the recent run of poor Renault engine reliability have cost the some considerable ground against the works outfit, leaving the Italian team perplexed as to why the bulk of the issues have befallen the Italian squad rather than the other Renault powered cars in Formula One. Renault Sport F1 head honcho Cyril Abiteboul recently claimed that the failures were more down to how the Power Units are installed and managed by the Faenza outfit than issues with the engine itself, something that Toro Rosso have vehemently denied, instead indicating that the high rate of failure could well be more down to their fight with Renault for constructors points than actual issues with how they are integrated within the Toro Rosso car.. "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" said Toro Rosso in a statement on Friday. "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 [Renault-powered] cars out of six finish the race, highlighting the poor reliability." However it would be the way Toro Rosso finish the statement that leads to the most raised eyebrows, playing on comments from Abiteboul that the issues must be Toro Rosso related as in Formula One there are no "coincidences", the team agree.. but probably not in the way Renault indicated in their initial take on the situation. "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." Let us not forget that Toro Rosso will be moving to Honda power for 2018 and this could be the beginning of the cracks finally starting to show in a relationship very much coming to the end of its time in Formula One..
