Rosberg tops a double red flagged Canadian Grand Prix FP3

Nico Rosberg fastest from Raikkonen and Grosjean in final free practice at the 2015 Canadian Grand Prix.

With just an hour on track teams had to set their cars up for qualifying and make up for the lost time from second free practice. But two red flags meant supersoft running was limited but when the chequered flag fell over the Circuit Gilles Villeneuve, Rosberg was the fastest man on track with a 1:15.660.

Hamilton had topped both Friday practice session with Nico Rosberg claiming second place in FP1 from Grosjean, while Vettel and Raikkonen led the Hamilton chase in the FP2 session stopped by rain.

But Friday practice did not go perfectly for Lewis however, as the championship leader hit the barrier at the hairpin after tip-toeing his way around the track on intermediate tyres. Other drivers also struggled to keep their cars on track over both sessions but no other driver found themselves in a barrier.

As for Saturday and the final practice session, the running got underway with Maldonado and Ricciardo leading a line of nine cars out on track before the Aussie went on to post the opening time of the session with a 1:24.212.

Ricciardo’s time soon improved but at the end of the opening fifteen minutes, the Ferrari’s held a one-two on the time sheet with Vettel on top of the order in the 1 minute 17’s. Coincidentally neither Mercedes cars had seen any running at this stage with both still in the garages.

Yet once Rosberg was on track he took a few laps to gain temperature into the tyres and brakes before posting a purple time in each sector to move seven tenths clear of Vettel in P1.

Hamilton meanwhile took a short while longer than Nico before leaving the pits but was unable to carry out a clean lap before returning to the pits. In the same time, Bottas and Massa moved ahead of Vettel by four tenths at the midway stage to suggest they may be able to utilise the Mercedes power advantage to secure a strong result in qualifying.

As for the Renault powered teams, they struggled to get out of the bottom half until Kvyat switched onto the supersoft tyres and moved into the top four, yet still six tenths down on Rosberg. Even when Kvyat improved on his time he was still unable to go faster than Rosberg, or even Grosjean who went faster than the Red Bull even while still on the soft compound.

Unfortunately for all on track, the red flag was brought out shortly after Raikkonen became the pace setter by just one thousandths of a second. This red flag was waved after Felipe Nasr lost control of his Sauber and crashed into the wall while weaving down the back straight in an attempt to get temperature into his tyres.

The session got back underway soon enough with all drivers running on the supersoft tyres. The option tyres also allowed Rosberg to improve on his best time and set the new benchmark by just shy of six tenths to Raikkonen who also moved clear of third placed Grosjean.

Unfortunately as everyone looked to carry out flying laps to prepare for qualifying another red flag was waving around the Circuit Gilles Villeneuve. This time the culprit was Jenson Button who parked his McLaren shortly after Alonso finally hit the track following an engine change.

Shortly before stopping, Jenson radioed the team and said: “Massive loss of power, like the ERS isn’t working. I think we have a bigger problem…I’ve just stopped the car.” Now the team will need to change his engine for tomorrow’s race, but it means Jenson will miss out on qualifying.

This red flag also marked the end of the session and Rosberg took the fastest time of the morning. Team-mate Lewis Hamilton was unable to post a flying lap all session and ended FP3 in 20th while Vettel ended the session in eighth.
