Marko moves to cool STR/Renault row
11 November 2017 – Helmut Marko says there have never been doubts over Renault's parity as an engine supplier, amid a row between the manufacturer and Toro Rosso.
Renault chief Cyril Abiteboul suggested in an interview to Autosport that Toro Rosso could be to blame for a recent run of failures, due to operational procedures.
Toro Rosso issued a strong statement on Saturday morning, in response to Abiteboul's comments, in which it put the full responsibility on Renault's side.
"The statement was a reaction to Cyril's interview yesterday, where he blamed the team for the power unit failures, which is absolutely wrong," Tost later explained, in follow-up comments.
"If we do something which is not okay then we tell it, but MGU-H failure or shaft failure is nothing to do with installation of the power unit.
"The fact is that we don't get new parts, we are just changing old parts from one power unit to the other, therefore we are suffering and therefore we have reliability issues.
"We are also not happy about this as we pay a lot of money, we just expect new, good material."
Red Bull advisor Marko, in a bid to calm the situation, defended Renault's record as an engine supplier, and reckons end-of-season tiredness played a role in the row.
"Over the last 10 years, many successful, we have been through every emotion with our current engine supplier," said Marko, in a statement posted on Red Bull's website.
"As usual, at the end of another long season, emotions are running high, but it is a valued relationship and will remain so.
"There has never been any question that we have not been treated fairly and equitably by our engine suppliers, and that is still true today."
