Lotus battle for the forthcoming season opener in Melbourne with next-best McLaren and Ferrari perhaps slightly off the ultimate pace.RESPECT FOR MERCEDESBut on Saturday (Mar 2 2013) Hamilton raced to the top of the times with the winter's best lap time.. until Nico Rosberg went even quicker in the first half of Sunday, the last day of running before the circus heads off to Australia.Auto Motor und Sport correspondent Tobias Gruner said: "Everywhere in the paddock, respect is being shown for Mercedes.”There are, however, outstanding questions.

"We will definitely be able to win a race at some point."Sauber's Nico Hulkenberg commented: "At the very least, Mercedes' betting odds have changed!"
