Red Bull team principal Christian Horner has admitted his team need to carefully look at their starts.
Both drivers have suffered from poor starts which have led to them dropping places on the crucial first lap.
Sebastian Vettel’s pole position in Germany was lost into the first corner after he tried to block Fernando Alonso. He bogged down on the start-ling which allowed not only F1’s most recent winner to pass him, but also Felipe Massa who started third.
Similarly, Mark Webber’s Belgium pole position was also lost after he dropped to sixth on the opening lap, before finally recovering to finish second behind eventual winner Lewis Hamilton.
Once again, a similar situation in Italy saw the Australian drop five places to ninth before the second lap had even begun.
This is an occurence which clearly worries Horner, who says the team are working hard to understand exactly what is going wrong when the lights go out.
“We need to look at it quite carefully because our starts at the beginning of the year were excellent, very strong,” he said.
“But over the last couple of races we’ve lost a bit of performance on the start line, so whether that’s an effect of low downforce is something we need to understand.”
