MARK Webber promised that there would be a bit of “carnage” when his brutally honest autobiography Aussie Grit was released.

He wasn’t kidding.

Along with tales from his decorated career in the sport, the book tells the story of his difficult relationship with Sebastian Vettel and, consequently, the Red Bull Formula 1 team, delivering a blunt assessment of his former teammate as well as key figures in team management.

Webber gives an insight into how Vettel avoided any kind of reprimand or sanction from Red Bull over his actions at the 2013 Malaysian Grand Prix, where he ignored the now infamous “Multi 21” team order and passed Webber to take the victory.

“When Ann (Neal, Webber’s partner) later pressed (Christian Horner) about why the team had never reprimanded Seb or issued any punishment for the ‘Multi 21’ incident, he admitted that the team had received a two-page letter from Seb’s lawyer a few days after the Malaysian race stating that they were in breach of his contract by giving him an ‘unreasonable instruction/team order’,” Webber wrote.

“Whatever (Vettel’s) thinking was, when he overtook me I wasn’t so much angry as very sad that the team had reached this sorry state.”

Webber also reveals his take on his deteriorating relationship with Vettel, which he believes began to slide as early as mid-2009 when Webber beat him to second place in the Turkish Grand Prix.

“It seemed the thought of me simply being quicker was not one he could entertain!” he wrote.

“There always had to be another reason why. Over time, I realised his meltdowns came when he thought he had done enough when in reality he hadn’t.

“To my way of thinking, if you get done fair and square on the day you should take it on the chin, but Seb’s arrogance meant he simply couldn’t comprehend how it had gone wrong and would take it out on the team or rather want the team to do something about it.”
