Mar.17 (GMM/ Lewis Hamilton has stepped up his rhetoric against rival Red Bull’s complaints.

After the British driver won dominantly in Australia, Red Bull declared the gap to Mercedes was too big and the rules too ‘complicated’ for formula one.

“It’s not (too complicated) for us,” the reigning world champion told Australia’s Seven Network on Tuesday during a visit to Sydney.

Red Bull chiefs are arguing the current rules are “killing” the sport, and have threatened to quit.

“It’s been interesting to see some of those comments,” Hamilton continued.

Asked if Red Bull is simply guilty of sour grapes, he answered: “I don’t want to get into the political side of things. I just drive.”

But Hamilton did observe: “People are always unhappy when they’re not winning.”

As for Red Bull’s failure to keep up amid the new turbo V6 era, the 30-year-old pointed out that Ferrari has managed to make a big step forward over the winter.

So Hamilton advised Red Bull: “You better hire some better people, I guess. We’ve hired great people and we’ve done a great job, and we weren’t complaining when they were doing it.”
