Who will be 2011 champion?
It is difficult to look beyond the Red Bull Racing drivers as the championship favourites as the car has looked so good in testing, both on long and short stints. I have a feeling that they still have not shown what they are capable of and we are not going to see that until this weekend's race in Australia.
Ferrari have looked good as well, but I think that the Red Bull has looked the stronger over a race stint and they will have a slight advantage in Melbourne.

McLaren-Mercedes were the other team, like last year, that I expected to be a factor at the front, but they look like they are off the pace from what I have seen in testing.
I would have to go for Sebastian Vettel to go on and repeat his success from last year and be champion for a second successive year for Red Bull.
He really impressed me with how he stepped up in the final races, and now that he has had that major breakthrough and won a title I expect him to only get stronger and he will be hard to beat this year in another good car.
Mark Webber has not won a championship yet and still has that hanging over him. He pushed Vettel hard last year and he will push him hard again this season and will win races, but he will have to settle for second best behind his German teammate.
Webber and Massa's chances?
I think Webber has a good chance of being close to Vettel; I mean, he almost won the world championship last year.
He let it slip in Abu Dhabi with a poor race and pit strategy and I still don't know why he was so off his game there, but generally he was always close to Vettel on the run-in, and drove a great race in Brazil.
It is important that he does not allow Vettel to get too much of a good start over him, but I do think he can be a factor in the championship hunt.
Felipe Massa, on the other hand, has a much harder task. He was well beaten by Fernando Alonso last year, and it has been Alonso who has been the quicker in all the testing I've seen.
I know Massa was recovering from the accident that sidelined him in 2009 and he had difficulties with the Bridgestone tyres, but he really was well beaten by Alonso.
I like Massa, but you do fear it is going to be more of the same for him this year, especially now that Alonso has had a full year to be settled at Ferrari, so I think he has a tall order for him to be fighting for the championship.
Who will cause a surprise?
I think Renault, Toro Rosso and Sauber have all made steps forward, but how much closer they are to the top teams is not clear.
Renault have got a new exhaust package and that has helped the chassis, but obviously the loss of Robert Kubica to the serious injuries he suffered in a crash in a rally in Italy is a big blow. He is a fantastic driver and was their leader and had a chance of race wins.
Nick Heidfeld is a solid substitute for Kubica, as the Pole recovers, and he will bring home plenty of points finishes, I expect.
The Toro Rossos look great in testing, particularly over long stints, and they look like they have made a big step forward, which should give Sebastien Buemi and Jaime Alguersuari the chance to show what they can do.
Sauber obviously made the headlines when Sergio Perez went quickest on one of the testing days in Barcelona. That time may have been done on low fuel, but you still have to be able to do the time and they do look in good shape.
Can the strugglers improve?
The Hispania Racing Team (HRT), given they have not being able to do any winter testing on their new car, are unlikely to progress much and I expect they will be at the back of the field again.
It was a bit concerning to hear Timo Glock say that he did not think that the Marussia Virgin team were where they wanted to be, and while there is no doubt they will have improved, it may well be they have not made a big enough step forward to catch the teams immediately in front of them.
Team Lotus look the team most likely to move up the order. They have certainly made the right noises in testing, and they will just be hoping to be reliable to ensure they can get some early finishes under their belt.
The one problem they face is that while they have progressed and should be more competitive, so have the cars that were immediately in front of them last year, like Toro Rosso and Sauber, so it is difficult for them, having to chase a moving target.
Team Lotus will be better, but whether it is enough for them to move forward up the order only time will tell.
Will new rules help the show?
The tyre situation is going to be a fascinating part of the season. There is quite strong degradation on the Pirellis and this means that the drivers have to be more considerate of how they drive to look after the tyres and prevent them from wearing quickly.
What you will see is the contrast in driving styles and the consequence that it has on the tyres.
At McLaren you have Jenson Button, who has a very smooth style behind the wheel, while his teammate Lewis Hamilton has a much more aggressive action, and it will be interesting to see if the Pirellis do suit Button more.
I am a little unsure on the rear wing, and am not sure the idea of designated spots to use it are going to work.
I am pleased that the FIA have said they are going to monitor how successful or not the scheme is and make adjustments as things go along.
The return of Kers comes after it was first used by some of the teams in 2009. Who can do the best job with it will be interesting, particularly at race starts.
McLaren probably had the best Kers system in 2009, but given the current concerns with the car and its competitiveness I don't think it is going to help them too much, other than at the start of races.
