Red Bull: Problems with KERS and communications

Red Bull had to battle on several fronts in China: against the tyres, the competition, their own KERS – and a wet microphone.

Christian Horner had mixed feelings after the Chinese GP. On the one hand, Mark Webber had delivered a bravado performance, advancing from 18th on the grid to third on the podium while on the other, Sebastian Vettel yielded pole position at the start, then fought his way back into the lead but still finished as runner-up.
"P2 and P3 may not be outright victory, but it's still an incredible team result," stressed Horner.

"Jenson [Button] will certainly be asking himself how he crossed the line in fourth position behind Mark Webber who started from 18th. We bagged a lot of valuable points today, so we are by no means disappointed."

For Vettel, things were not going at all smoothly, as he was having to cope without his radio or his KERS at various times in the race. "KERS worked in both cars," said Horner. "From about the halfway point, we weren't using it on every lap."

Vettel's radio was out of commission for much longer becasue of a wet microphone, it seems.

"Sebastian could hear us all the time, but we couldn't hear him. Eventually, we found a way to communicate with him during the race. There were buttons that he could press to confirm that he'd heard us."
