F1 returns to Shanghai for the Chinese Grand Prix just five races since its last visit.

The earlier appearance for the track on the schedule means the teams can expect cooler conditions – and a greater chance of rain.

They will also have to get to grips with the super-soft tyre which caused so many problems in Melbourne. And tomorrow’s ruling on the diffuser appeal could see changes in the balance of power at the front of the field.

The Chinese Grand Prix makes its sixth appearance on the F1 calendar and, for the first time, ever, the race is being held in April instead of its usual October slot.

April in Shanghai sees average temperatures around 4C cooler than in October. Perhaps more significantly, average rainfall in April is 90-95mm compared to 55-60mm in October. The 2006 and 2007 Chinese rounds were rain-affected.

Partly because of the cooler conditions, this year the teams have a radically softer selection of tyres to use. Last year Bridgestone brought their hard and medium compounds – this year the teams will use the medium and super-soft tyres.

This was the same selection the teams had in Melbourne, where they found the super-soft tyres degraded rapidly after just a few laps. If we see a repeat of this phenomenon in Shanghai the teams will be faced with a difficult strategic question: use the super-soft tyres in the first stint to get rid of them and hope to take advantage of a safety car period; or save them until the end when the extra rubber build-up on the circuit may help them last longer.

The Shanghai races comes after the teams’ first two-week break of the season, and it’s likely many of them will have new parts to test on Friday. If tomorrow’s appeal court hearing upholds the legality of the ‘double decker diffusers’ used by Brawn GP, Williams and Toyota, keep an eye out for which teams have their own versions ready to run. If the appeal goes against the ‘diffuser three’, all eyes will be on the times sheets to see how much of an effect it has on their performance.

Shanghai has the second-longest flat-out section of any F1 track on the calendar this year: the 1.37km blast from turn 13 to 14. This will likely hand a considerable advantage to any KERS-equipped cars when it comes to overtaking. Will any other drivers join the seven that have used the device so far?

Drivers to watch

Heikki Kovalainen – It’s easy to get distracted by the Lewis Hamilton Show, particularly when Kovalainen has failed to complete a racing lap so far this year. That can’t last forever though – remember Sebastian Vettel last year – and Kovalainen has shown promising pace in qualifying and practice. A surprise could be on the cards.

Fernando Alonso – Made a scintillating start at Sepang, watch for more of the same on Sunday.

Nico Rosberg – Fastest in five of the six pre-race practice sessions so far, can Rosberg finally translate promise into performance?

Rubens Barrichello – It’s two-nil to Button so far, and if Barrichello wants a crack at the championship this year he needs to get on terms with his team mate.

  1. I would think the dd diffuser teams already have a conventional diffuser ready just in case.
    Forgot to mention great post. Can’t wait to seeing your next one!

  2. i hope they are termed illegal this will bring the whole field back together and make for better racing.Remember that all the drivers without this diffusers are saying they are lacking rear downforce and grip which was easily seen in sepang with cars twitching threw the corners and on exit.I still firmly believe if the ruling goes against the 7 other teams they will shelve there season and concentrate on next year.Remember what alonso said it not just putting a new diffuser on and you go 2sec faster they will have to redevelop the whole car.There is no testing so if they put on a new one for spain and it doesn’t work that race becomes a test season and the next and the next how long until they just flag it especially with brawn racing away with the championship ‘that would be 4 wins by spain.lewis won last year with only 5 race wins

    1. eh? How have we not had good racing…everyone from F1 commentators to us armchair pundits have been saying how good the racing has been this year!

  3. I actually think Barrichello is faster than Button. He had a bad start at the beginning of Australia and had a damaged car, and still got second. Malasia was luck of the draw for pitstops. In the dry, Barrichello was closing in on him. Qualifying can be explained by the weight of the extra fuel.

    1. An alternative view…

      Barrichello was chasing second place and therefore pushing
      Button was sitting pretty in first and therefore not pushing

      Barrichello was chasing second place and therefore pushing
      Button was sitting pretty in first and therefore not pushing

      The only way to determine which is faster is either in Qualifying 1 and 2 (not 3 because fuel load plays a part), or when we see them actually racing close for the win (or other position). So far in qualifying Barrichello has beat Button 3 to 1… I never said I didn’t agree with you ;)

      It will be interesting to see how they match over the season, one aspect I am watching with much interest.

  4. I think we will see one of the teams with KERS to make it on the podium. Just a ballpark figure – if KERS can bring an extra 0.3sec lap time reduction on their car, that’s about 16secs for all of the 56 laps. Brawn will still be there same with Toyota.

  5. I agree with 1994fanatic. For Brawn, Button is driving well but I think Barrichello will always be the faster all things equal. Williams will be up there and RBR will be snapping at the both of them. I think the KERS cars will fall off alot in the long mid corners in the race journey.

    1. Watching Button is like watching an artist at work though. He is so smooth, rarely a correction, and yet consistently sooo fast!

  6. I expect Brawn to do well again in China. If the diffusers are deemed legal, once all the others fit them to their cars, then we’ll see exactly how good Brawn are.

  7. Is it right to put 7 teams re-structure their car. Like ferrari announced new designing for DD diffuser takes 20 million €!!! 7 X 20….well…not cheap…

    3 X 20 for normal diffuser is much less consuming….

    that´s one point of view for that case

  8. 1) Rosberg
    (Kind of wishing on the Rosberg pick. Could be Jenson.
    Also, There is more to the Brawn than just the diffuser that makes that car quick. You could take away the diffuser, (but they won’t have to), and it would still be right up there.

    I think you are right, Leaf.
    Brawn GP is run by the same Ross Brawn who realised that Schumacher could serve his penalty in the pits at the end of the British Grand Prix because the Ferrari pit was beyond the start/finish stripe.
    The man is a genius in spotting gaps in the regulations and ways to exploit the pre-conceptions of others.
    With the diffusers, the Brawns might be half a second a lap quicker than anyone else. Delete the diffuser and they might be just a quarter second, but they would still be faster.

  10. One of the Brawns will get pole. And if he doesn’t completely screw up the start again (as each of the Brawns have already done in the first 2 races), the Brawn should win fairly comfortably. I think it’s Barrichello’s turn to win.
