Lewis Hamilton and Sebastian Vettel have just had a little moment at the pit lane exit.

Hamilton appeared to be attempting to pass a number of cars queuing to do practice starts when the Ferrari of Vettel pulled away just in front of him.

Hamilton waved his hand at the German and quickly got on the team radio, saying: "Ferrari's just so dangerous.

"As I was pulling away, I almost crashed into him."

That should spice things up.

Four times a previous pole-sitter and a three-time winner, it's no surprise to see Lewis Hamilton leading the way in laps led at the Shanghai International Circuit since the race was first held in 2004.

1. Lewis Hamilton 141

2. Fernando Alonso 119

3. Nico Rosberg 78

4. Jenson Button 75

5. Sebastian Vettel 73

It's time to say a quick happy birthday to former Brabham, Ferrari, Lotus and Williams driver Carlos Reutemann, who turns 73 today.

The Argentine won 12 grands prix and scored 45 podiums in a 146-race career between 1972 and 1982.

Despite being a front-runner for several years, the world title proved madly elusive for Reutemann (below). The closest he came was in 1981, when he lost out by just one point to Nelson Piquet after the final round at Caesars Palace.

Also celebrating today is Italy's Corrado Fabi, who turns 54.

The younger brother of fellow F1 racer Teo Fabi, Corrado raced in 12 grands prix for Osella and Brabham between 1983 and 1984.

"This weekend is the first race Sauber have had both cars in the top 10 on the grid since the US Grand Prix at the end of 2013. Marcus Ericsson, 10th and a place behind team-mate Felipe Nasr, described this as 'a great achievement'. 'We knew it was possible but it is so close and we needed to get everything right.'

"For Nasr, it was confirmation of his stellar performance on his debut in Australia, after a difficult weekend in Malaysia when fate seemed to conspire against him. And it could have been even better - he said he lost a front wing flap at the start of his final run, which cost him a couple of tenths of a second, which might have moved him ahead of Lotus's Romain Grosjean for eighth. Sauber's big step forward this year is clearly mostly to do with a corresponding advance by Ferrari on their engine - Nasr admitted the cash-strapped team were still lacking significant amounts of downforce."

If Fernando Alonso wants to maintain the above record, he'll need a significant change in fortunes at McLaren.

He's yet to see the chequered flag in 2015 having missed the first race with concussion and then retiring in Malaysia a fortnight ago.

An engine failure in FP3 yesterday was also a reminder of the McLaren-Honda's fragility.

"Manor's Will Stevens was buoyant after qualifying and is very much looking forward to his first race for the team in Formula 1 - which is only his second grand prix after his one-off for now-defunct Caterham in Abu Dhabi at the end of last year.

"Various problems, all rooted in the team's 11th-hour rescue by its new owner Stephen Fitzpatrick of Ovo energy, have meant Stevens has had a troubled time so far this season. But he described Saturday as 'a good day', adding that he had even managed to get a run on high fuel in morning practice. Those were his first laps in race trim ever in the car, so the race will be a journey of discovery."

A couple of years back BBC Sport reflected on some of the most memorable moments from previous Chinese Grands Prix.

The event was first held at the Shanghai International Circuit in 2004 and was won by Ferrari's Rubens Barrichello. The race had six different winners in its first six races, including Michael Schumacher, Fernando Alonso, Kimi Raikkonen and Jenson Button.

Lewis Hamilton, victorious in 2008, became the circuit's first repeat winner in 2011. He added a third win last season and is gunning for number four today.

"Williams have had a bit of a reality check so far this season. Having expected after pre-season testing to be neck-and-neck with Ferrari, to be some way off their pace has been an unpleasant surprise. But things are much more to their liking in China, with both Felipe Massa and Valtteri Bottas managing to split Sebastian Vettel from Kimi Raikkonen, and aiming to at least replicate that in the race.

"Massa's lap, in particular, won praise from technical boss Pat Symonds, who said: 'Felipe was really on fire in qualifying. It was a great lap.' Massa himself described it as 'amazing'. But Symonds admitted that keeping Raikkonen behind in the race will not be easy - Ferrari, he said, were fundamentally quicker still."

As always we want your involvement this morning.

Is Lewis Hamilton going to run and hide today or can team-mate Nico Rosberg keep him honest? And what of Ferrari? Can their better tyre management really close a gap of almost a second in qualifying?

McLaren driver Jenson Button: "I don't know how its going to go. We expected more from qualifying.

"We didn't have the pace. I don't know why but we will have a look at it. There is improvement needed but we're looking forward to what we have today."

Ferrari driver Sebastian Vettel: "It's great to see there is so much support here. It seems to be growing every year."

Asked if his win in Malaysia would have given Mercedes a wake-up call, he says: "I hope they didn't wake up.

"It will be tough. We have to be realistic. We will try to be a bit closer to them again."

Mercedes driver Nico Rosberg: "I'm feeling good. Yesterday was frustrating but there is going to be a lot of opportunity today.

"There is going to be a lot going on with tyre degradation and fuel strategy. It will be quite difficult to work out what is going on at home but in the car as well. There are so many different scenarios but we hope to be a bit quicker than Ferrari today.

"I have to try to get some points back on Lewis and Sebastian as well. It's an important day."

Mercedes driver Lewis Hamilton: "I feel pretty good. I have got amazing support here.

"You have to be a real attacker here. Here, you just have to look after your tyres and we have to try to do a better race than Ferrari."

"Ferrari are hanging their admittedly slim hopes of beating Mercedes on their better tyre wear, which was key to their win in Malaysia. But will it be enough? 'Mercedes are very quick,' Sebastian Vettel said. 'Both drivers do a good job, and that makes them difficult to beat. We are very happy where we are. I hope we can be a bit closer in the race. But "close" and "challenge them so they make mistakes" are different stories. Red Bull and Williams also seem quick this weekend so it will be a long race.'

"The race is expected to be a two-stop strategy and as long as Mercedes can do two stints on the soft tyres, as Ferrari can, it is hard to see on the face of it how Vettel can challenge Hamilton, given the significant pace advantage the world champion has had all weekend. Hamilton was 0.9secs clear in qualifying, 0.4secs in most practices, and 0.7secs on average ahead on the average of his race-simulation run in Friday practice. Realistically, Ferrari admit that their hope is to split the Mercedes, but know that even that is a stretch."
