Inside the Race – Round 1: Australian Grand Prix
"A talking point in Australia was Mark Webber’s consistent lack of comparative pace to teammate Vettel in both qualifying and the race. From the differential table above, Webber lost the vast majority of time over 2/3 of the lap; which is very atypical for past comparisons between the dueling Red Bull teammates. As will be shown later, Webber also suffered from tire degradation in the race far and above the levels experienced by Vettel. At the weekend’s conclusion, Webber informed the media that he pulled off the track immediately upon crossing the finish line as a precautionary measure because he felt something was just not right with his chassis. Red Bull confirmed it would be conducting a full strip-down of Webber’s car, and there are unconfirmed reports that the team has already found a mechanical issue that was the culprit of Webber’s problems in Australia. Point of all this being that its far too soon to write Webber off as a non-contender to Vettel."
