Like yesterday, the lads at Mercedes are pushing the boundaries on a very 'green' track.

Within a few seconds of each other, Lewis Hamilton locks his right front into the hairpin while Nico Rosberg misses the apex at turn six.

The track is starting to come to the drivers now and we have a first lap of the day in the 1:16s.

Nico Rosberg is the man atop the pile, a 1:16.783 putting him around three tenths clear of both Valtteri Bottas and Felipe Massa, the Williams boys already looking much better than they did in Monaco.

Former motorsport boss Max Mosley says Formula 1 "needs fixing" as the sport continues to wrestle with decisions over its future direction, writes Andrew Benson.

Mosley, president of governing body the FIA from 1993 to 2009, said that "there are clearly things wrong".

"Four of the teams haven't got enough money and other teams have so much money they waste a lot of it," he said.

Mosley said the governance structure that cuts small teams out of decision making was "completely wrong".

The full BBC interview with Max Mosley will be shown in our qualifying show later today.

"Apologies, I was incorrect on what happens to Max Verstappen if he cannot serve his full 15-place grid drop. It does not get carried over to the next race, there is a sliding scale of time/stop-and-go penalties during the race depending on how many places he cannot serve."

Around a dozen cars have set times now but there's not much to read into them at this stage.

Ferrari's Kimi Raikkonen leads the way at present with a 1:17.681 on the soft tyre, nearly two seconds off yesterday's benchmark time in the dry set by Lewis Hamilton on the super-soft.

After Mercedes' strategic error under the safety car Monaco, we're taking a chance to look back on famous moments when pit stops have gone wrong.

David Coulthard's slide into the wall when entering the pits while leading at Adelaide in 1995 is one famous example, but what others stand out for you? There's plenty to choose from.

"Jenson Button had a difficult day in the McLaren on Friday. Delayed by a gearbox problem in the first session, he was half a second slower than team-mate Fernando Alonso in the second, and BBC F1 analyst Allan McNish said Button looked tentative on turn-in for the chicanes and was losing time there.

"'We have a lot of work to do on the set-up,' he admitted, while Alonso said he was 'happy with the balance' - and looked it as he attacked the last chicane.

"Button said he thought 'top 10 will be difficult', and Alonso said he was expecting 'about P12 or P13 in qualifying'.

"On the plus side, Honda has brought engine upgrades here, using up two of their nine available in-season development tokens. On Thursday, the drivers said these were for reliability and efficiency and although Honda F1 boss Yasuhisa Arai said after Friday practice that he 'had a very good feeling and we're positive not just for this race but also the next race and the one after that'.

"But on Saturday morning he admitted to this writer that there was 'not so much' extra performance. And the speed trap times revealed the McLarens right at the bottom, ahead only of one Manor."

All that rain yesterday washed away what rubber had been added to the track in FP1, and Red Bull's Daniel Ricciardo has just demonstrated the upshot of that.

The Australian runs out of grip into the first turn and takes briefly to the grass before continuing.

"One of the surprises of Friday was the pace of the Lotus cars, right up there behind the Mercedes and Ferraris as the third fastest team in both sessions, mixing it with Williams and Red Bull. The team have no special updates for this race, other than the usual low-downforce package required for this track and trackside operations director Alan Permane admitted the performance of Romain Grosjean and Pastor Maldonado had been a bit of a surprise.

"'We're a bit more competitive than I expected,' he said. 'We're on a very normal programme, too. Let's wait until 3pm on Saturday before getting too excited, though.'"

Final practice is under way.

Pastor Maldonado is the first man out. The Lotus cars have looked good this weekend and they have realistic expectations of both getting into the top 10 come qualifying later today.

"Ferrari's pace on the race-simulation runs before the rain hit in Friday practice was hot. Almost too hot, one suspects, for it to be real. Sebastian Vettel and Kimi Raikkonen, running one type of tyre each, were both about a second a lap quicker than the Mercedes drivers. Far too much to have been explained by a 15bhp engine upgrade.

"The suspicion is that they must have been lighter on fuel than the silver cars. Ferrari technical director James Allison said that the weather had 'mucked things up', making the session 'hard to judge'. But he is clearly not expecting an all-red front row. Sitting next to Paddy Lowe, his opposite number at Mercedes, in the official news conference, Allison said: 'We think we went quite well but we also think these guys are probably hiding their light under a bushel.'"

"A truncated and rain-affected day of practice on Friday has set a delicious tone for the Canadian Grand Prix. Lewis Hamilton looked fast but had the sort of edgy, incident-packed day that suggested the disappointment of Monaco might still be preying on his mind, no matter how much he says it is not.

"And Ferrari, with an upgraded engine, look close enough to give Mercedes at least pause for thought.

"With Friday's rain a distant memory, an enticing day of the sort of action the Circuit Gilles Villeneuve seems to guarantee is in prospect."

"Toro Rosso have decided to change Max Verstappen's internal combustion engine. That will be his fifth this year, adding a 10-place grid penalty to the five he already has for crashing into Romain Grosjean in Monaco.

"If he does not qualify in the top five, the remainder of the penalty will be added on at the next race, according to the structure of the FIA's penalty system."
