Mar.5 (GMM/ Mercedes remains “hungry” for F1 success in 2015, the German carmaker’s chief executive Dieter Zetsche insists.

“We are hungry and not yet satisfied,” he reportedly said at the Geneva Motor Show, echoing team boss Toto Wolff’s claim that Mercedes wants to prove it is in Ferrari and Red Bull’s league by winning multiple titles on the trot.

Zetsche is quoted by La Gazzetta dello Sport: “We have worked hard over the winter and have a good car. But we cannot know how we will go before we race.”

As for claims the so-called engine development ‘unfreeze’ will specifically hurt Mercedes, however, he insisted: “I don’t think it is a disadvantage for us.”

What may ultimately hurt Mercedes is a political push by key rivals like Ferrari and Red Bull to radically shake up the current technical rules by 2017.

Zetsche responded: “I think there should be internal discussions, but I also think that we already have everything we need for a great show.”
