Lewis Hamilton says he didn't expect to have such a large time advantage over his Mercedes team-mate Nico Rosberg at the end of Friday practice in Canada, while highlighting the threat from Ferrari.
The reigning F1 world champion demonstrated his impressive pace around the Circuit Gilles Villeneuve as a four-time race winner at the track by topping the timesheet with a 1m 14.212s – a lap one-tenth under his pole position time from 12 months ago.
Hamilton has pulled out a two-tenths gap on Sebastian Vettel while moving over half a second clear of Rosberg over a single hot lap which has come as a shock to the British driver.
“It was surprising to see the gap between Nico and myself but for sure a very positive feeling,” Hamilton said. “I can just keep pushing, keep working, there's more time in it. There was another lap I was up another tenth and a half so I know I can find more time, which is good. I don't know what Nico's problems are, he struggled a little bit more today.”
As has come tradition, the Mercedes driver has signalled his concern about the pace of the Ferraris after Friday free practice and feels the Italian manufacturer has upped its straight-line speed with the use of its new turbocharger which is being introduced for the Canadian Grand Prix.
“The Ferraris look very quick. I think they've got a new turbo so I think they've picked up their pace in a straight line,” he said. “Whether or not they've turned their engine up to test that, I assume they probably have. But we will see tomorrow I guess.
“Hopefully we're going to have a bit of a race here. These tyres, the supersoft wears out a little bit more than the rest but the tyres aren't particularly that soft so I don't think it's going to be a particularly challenging race if it stays dry in terms of looking after the tyres.”
