Red Bull will run away with the Chinese grand prix, German driver Timo Glock predicts.
Back-to-back 2011 race winner Sebastian Vettel was six tenths clear of the sister RB7 in initial Shanghai practice, and more than two seconds faster than the chasing McLarens.
"Red Bull look better than they were in Malaysia," Glock, who drives for the struggling Virgin team, told the German broadcaster Sky on Friday afternoon.
"It was clear in first practice that this is Red Bull-country," he added, "just as it was in previous years."
