COLOGNE, Germany - Formula 1 has collected two category wins at the 2011 Professional Motor Sport World Expo awards.India's new Buddh circuit took top honours in the "best circuit" category, Red Bull's title-winning RB7 was Car of the Year.The winners were decided by a judging panel that included such figures as Gary Anderson, Michael Andretti and Pascal Vasselon and announced during a ceremony in Cologne.Anderson commented on the Indian GP venue: "With adequate facilities to put on a great event, it will mature into one of the best."'McLAREN HAS THE EDGE'GP2 engineer Jordi Riba said: "The RB7 got my vote for its awesome domination but also for its innovative rear packaging, with the kers alongside the gearbox and the pull-rod suspension."Damon Hill thinks the team will have a tougher time in 2012, perhaps because McLaren has better drivers. He believes Lewis Hamilton and Jenson Button arguably outpaced Vettel and Mark Webber.Hill said: "I think at the moment they (McLaren) might have the edge on Mark in the Red Bull."It's harder when you've won to then steel yourself and put in the same effort again - to win again and keep doing that. It's much harder on Red Bull to carry that. In some ways it's easier to catch up."
