Vettel scoffs at Dennis' 'low fuel' theory

Sebastian Vettel on Thursday scoffed at Ron Dennis' suggestion that Red Bull did not tell the truth about its problem in the Bahrain season opener two weeks ago.

Having initially said a failed exhaust was the reason for the German's slowed pace, the team later clarified that it was in fact a spark plug problem.

But Dennis, the former McLaren team boss and ongoing chairman of the Woking based group, speculated last week that Vettel may actually have been running low on fuel.

"Maybe Ron Dennis wanted to attract attention with his theory, because otherwise no one asks for his opinion anymore," Vettel, 22, is quoted as saying from Melbourne by Germany's Auto Motor und Sport.

To reporters at Albert Park, the Bahrain pole sitter and early race leader reiterated that his problem was caused by a spark plug with a broken tip.

So why did he pull to the side of the track immediately after the chequered flag, if he had not run out of fuel?

"Because at the time I thought the exhaust was broken and I didn't want to do any more damage," he explained.
