Sebastian Vettel admitted that the second free practice session for the Canadian Grand Prix had been 'more like rally cross than F1' after drivers struggled on the softer Bridgestone tyres.
The German posted the quickest time during Friday practice for Red Bull after edging out Ferrari's Fernando Alonso at the top of the times and while he was pleased to show the competitiveness of the RB6, Vettel admitted that tyres would be a key factor in the race.
“It's looking okay for us, we're quite competitive,” he said. “The secret here is the tyres; everyone was sliding around a bit at the end – it was a bit more like rally cross than Formula One!
“The track started very green this morning, but that's normal and it will improve as the weekend goes on. The secret with these circuits is not to panic, as they tend to come towards you. We only made some small adjustments between the two sessions.”
Team-mate Mark Webber was off the pace with the 14th quickest time in the first session, but the championship leader ended the day fourth after session two and predicted a tough fight in qualifying.
“It was a pretty good day – we were pleasantly surprised with the pace,” he said. “We're going to have a tight fight with everyone tomorrow, but the car ran really well today. There was some graining with the option tyre, but they'll get better as the track rubbers in, so I'm not worried about it. We're happy with how today went, it was good.”
