MELBOURNE, Australia (AP) — Formula One's season-opening race ended in rancor and controversy Sunday as initial second-place finisher Daniel Ricciardo of Red Bull disqualified for a breach of fuel regulations, five hours after Mercedes driver Nico Rosberg took the checkered flag.
Ricciardo's exclusion from the results tarnished what had been a day of celebration for local fans, who were jubilant that the Red Bull driver had apparently become the first Australian to finish on the podium at his home race.
However just before midnight, stewards ruled that Ricciardo's car had "exceeded consistently the maximum allowed fuel flow" and that the team refused an instruction from the race's technical delegate Charlie Whiting to change the fuel-flow sensor before the race and a further request during the race to reduce the fuel flow.
Red Bull immediately announced it would appeal the decision.
"Inconsistencies with the FIA fuel flow meter have been prevalent all weekend up and down the pit lane," a Red Bull statement said. "The team and (engine supplier) Renault are confident the fuel supplied to the engine is in full compliance with the regulations."
The exclusion capped a day of shocks at the Albert Park street circuit.
Thought Rosberg's victory was little surprise, given Mercedes had been the dominant team in preseason testing and across the race weekend in Melbourne, few would have expected pole sitter Lewis Hamilton and defending four-time world champion Sebastian Vettel to be mere onlookers after half a dozen laps.
Both Hamilton and Vettel suffered engine failures, illustrating the difficulties all teams are having getting performance and reliability out of the sport's new V6 hybrid engines.
Ricciardo's disqualification meant Kevin Magnussen was promoted to second in his debut race, ahead of his McLaren teammate Jenson Button, giving the team a bright start to the season and the lead in the constructors' championship after a very disappointing 2013.
Rosberg started third on the grid and was first to reach turn one, then drove away from the field to eventually win by 24.5 seconds at the Albert Park street circuit. The margin of victory and the authority of the performance showed why Mercedes is considered a strong favorite to finally win its first constructors' title this season.
"I had an unbelievably quick car today," said Rosberg, whose world champion father Keke won the inaugural Australian F1 GP in 1985. "It was such a pleasure to drive, it's such a great feeling and I really look forward to the new races."
Rosberg's delight was a contrast to the disappointment on the other side of the garage as Hamilton quickly retired a car that was only firing on five cylinders.
