Renault admits Vettel failures 'unacceptable'
11 September 2012 – Renault Sport F1, engine supplier to Red Bull, has apologised for two more alternator failures over the Monza weekend. Both struck the car of Sebastian Vettel, one in Saturday practice and the other in Sunday’s race. They were identical problems to the one which removed the double Champion from the lead of June’s European Grand Prix.
‘This weekend has not been acceptable from either a performance or reliability point of view,’ Renault says in a frank statement. ‘We have to apologise to Red Bull for the two failures on Sebastian's car. In both cases the alternator failed. We introduced a new spec’ of alternator following the problems in Valencia and believed this would overcome the issues.
We are still looking into why the part failed again here but we do know that, even though the alternator was being operated entirely within the prescribed range, the part itself overheated and shut off the power supply. This is a priority between ourselves and our suppliers and we have to ensure we are fully on top of the problem before Singapore.’
The French company has also taken full responsibility for a KERS failure on another customer car – the Lotus of substitute driver Jérôme d’Ambrosio.
‘Clearly these types of issues should not happen and we will work tirelessly between ourselves and our suppliers to be back on form in all areas in Singapore and for the rest of the season,’ the Renault communiqué concludes.
Renault supplies engines to four F1 teams: Red Bull, Lotus, Williams and Caterham.
