Montreal: Lewis Hamilton topped the times for Mercedes in Saturday morning's final free practice session for Sunday's Canadian Grand Prix, the 29-year-old Briton outpacing nearest rival Felipe Massa of Williams by nearly half a second.
Hamilton's championship leading German teammate Nico Rosberg was third quickest in the second Mercedes on a warm morning at the Circuit Gilles Villeneuve where the track temperature reached 35 degrees Celsius towards the end of the session.
Massa's lap, on super-soft tyres in the closing minutes, not only split the two dominant Mercedes cars, but also showed that his team were extracting more performance from that rubber compound than the championship leading team.
Both Hamilton and Rosberg struggled with the 'super-softs' and were unable to clock improved lap times on the red-walled tyres in the final minutes.
