The fastest time today has been Kimi Raikkonen's 1:17.375, set on the pink hyper-softs.

Pirelli have announced that the hyper-softs will be available for the seventh race of the season - the Canadian Grand Prix from 8-10 June.

Pirelli traditionally brings their softest tyres to Montreal, with the hypersoft, ultrasoft and supersoft the three compounds to be made available to teams for this year’s race.

Fancy a little glimpse of the action? Luckily Rob is in position and has sent us this clip of Lewis Hamilton.

Hamilton is fourth quickest and has done the most laps at 75.

He wants more too, as he has just gone back out there.

The official Twitter account of the circuit certainly liked that Raikkonen effort.

Kimi Raikkonen is now a second faster than anyone else after smashing down a lap of 1:17.375 on the hyper-softs.

Still a bit slower than Sebastian Vettel from yesterday though, but his unofficial track record of 1:17.182.

Romain Grosjean (1:18.590) and Brendon Hartley (1:19.152) have also gone quicker recently.

Williams deputy team principal Claire Williams talked to the media here today.

“It is always fairly difficult with testing,” she said when asked to assess the team’s progress. “You can look at the time sheets; they are a relatively good barometer of where we are, but we have not had the easiest time over the past few days that we have been here.

"Certainly last week was difficult; it was difficult for everybody with the weather. But we have once again found it quite difficult working with the tyres and trying to switch them on, particularly the softs, the super-softs and the hyper-softs.

“Overall we did great job to get a fully and totally revised new race car here. That was a piece of work that a few of us back at the factory were certainly worried might be a bit challenging to get it here. So that was good. I hope that we are fighting for fourth this year.”

Robert Kubica was supposed to drive today, but he volunteered to step aside so the race drivers could get more track time.

Kimi Raikkonen was feeling unwell on Wednesday, but is back today, and at the top of the charts.

His effort of 1:18.238 is the time to beat. It is beatable though as his team-mate Sebastian Vettel set the fastest lap recorded at the circuit with an effort of 1:17.182 yesterday.

Not been much coming from the Renault social media team today as their man Carlos Sainz has only done four laps, the lowest amount of any of the 10 drivers so far.

"Gearbox gremlins" is what they put it down to.

MrB: Based on their run of woeful pre-season testing performances McLaren should start selling ad space on the recovery truck.

Ben: Wenger's style Boullier OUT ! Alonso OUT ! Then we will see.

McLaren. The Arsenal of Formula 1?

Worries for McLaren and Renault, but not so for Haas. Romain Grosjean has just moved into second, quicker than Lewis Hamilton, with a lap of 1:19.098, and wait, he goes even quicker with 1:18.590 on the super-softs.

Haas came eighth in the constructors' championship last season, with only McLaren and Sauber behind them, but could this be a good year for them?

It has also been a worrying day for Renault as Carlos Sainz could only manage four laps, with a gearbox issue.

We are hearing they are changing the engine now and investigating the cause of the trouble.

Both Sainz and Nico Hulkenberg are pencilled in to be in action today.

So, if you are just joining us it has been another frustrating day for McLaren and Fernando Alonso as he ground to a halt at turn seven of his seventh lap.

Here, courtesy of the Formula 1 Twitter account, are six seconds of Alonso in action.

We don't know when, or if, we will see Alonso again so savour this video.

Sergey Sirotkin has done 49 laps for the day, but is now back in the pits.

Meanwhile, his boss Claire Williams faces the media. She is probably going to get questions on whether they have made the right decision with their selections as Robert Kubica has outpaced both Sirotkin and Lance Stroll in testing sessions.

Vettel fastest yesterday. Raikkonen fastest today. Will this be Ferrari's season?

Formula 1, but from a different camera angle.

You have Force India's social media department to blame for getting a bit dizzy with footage of Esteban Ocon leaving the garage.

Kimi Raikkonen's best time was 1:18.298, but they have trimmed that down, by six thousandths of a second to move to 1:18.292 on the super-softs. Ferrari was fastest yesterday and are again today.

Phil Evans: Don't panic everyone! It's just a ploy by McLaren to interrupt everyone's long runs. Come Australia they'll be on the front row. Honest. Please...?

David Nutley: I always felt McLaren were unfair to Honda last year, claiming they 'probably' had the best chassis, and would be on podiums if it wasn't for Honda. Got a LOT to prove now, with a car that always breaks down, while the Toro Rosso grinds out times and laps day in day out.

We are hearing that Renault have been hampered so far today by a gearbox issue.

Carlos Sainz has only been out for four laps and has not set a time. Fernando Alonso, who stopped on the track in his McLaren, is the only other man to have not set a time.
