Mar.27 (GMM/Inautonews.com) Lewis Hamilton may not have been as dominant in Melbourne as first thought.

Germany’s Auto Motor und Sport reports that a detailed investigation by Mercedes showed that it got its numbers wrong regarding Nico Rosberg’s fuel strategy.

Team boss Toto Wolff had said after Australia that the German “did not have the weapons” to fight against Hamilton in the race because of fuel consumption.

But the report on Friday said Rosberg had more fuel left in the tank after the race than engineers had expected.

“Obviously,” said Auto Motor und Sport, “the calculations regarding fuel were wrong.”

1997 world champion Jacques Villeneuve is also not writing off Rosberg after Australia.

Asked by Brazil’s Globo to nominate his pick for the 2015 title, the French-Canadian said: “I’m betting on Nico. I think he is the most hungry for this season.”
