Here is 8 minutes video preview of 2009 F1 season and 2009 Australian GP. This was a very quick edit as I needed to get it all together before leaving for Australia. Included is the awesome animated footage from Red Bull that you might have already seen – the older with Sebastien Vettel explaining the new rules as well as the very recent one showing us how the F1 car comes to life. The animations are great, they explain the changes in F1 ahead of 2009 season quite well and so they made it to this video edit 
. Then of course the virtual lap of Albert Park circuit in Melbourne, few shots of Toyota, McLaren and Red Bull, one engine blow up, sound of Mercedes F1 V8 engine and introduction of all 2009 F1 cars and drivers.
Melbourne’s Albert Park is a stop-start mixture of temporary street course and a purpose-built track. This means the circuit includes an interesting variety of corners with unusual geometry and a constantly evolving track surface. Setting up the car is therefore a challenge, which is further complicated by the fact that most of the sixteen corners are really quite different with each one presenting a different sort of challenge for the cars and drivers.
Aerodynamics
Melbourne is on a par with the aerodynamic demands of Silverstone or Sepang and therefore requires a medium to high downforce set-up. With the introduction of moveable front wings, the drivers will be able to change the angle of their front wing by six degrees twice per lap (once to change to the new angle, and the second time to return to the original setting) which could be used to help balance the car between two corners or to aid following another car closely.
The circuit features a few critical high-speed corners, such as the fast fourth gear open chicane that forms Turns 11 and 12, which is perhaps the most challenging part of the lap. By using a higher downforce set-up, the drivers will hope to get good traction on the exit of the slower corners, which is important for carrying good speed onto the straights.
Suspension
Melbourne has a number of chicanes where a responsive car with a good change of direction is critical. The suspension therefore has to be relatively stiff to achieve this, but at the same time the car needs to be soft enough to use the curbs and have good stability under braking. An optimum set-up therefore demands a compromise, dovetailing hard and soft settings accordingly.
Brakes
Albert Park is a demanding circuit on brakes with six major braking zones demanding stops from over 300 km/h. It is not the severity of the braking, but the frequency that makes an efficient brake cooling solution a priority during the race. The track surface can be bumpy in the braking zones, but nothing too significant and a soft enough car should be able to ride the bumps without locking up under braking.
Tyres
The temporary nature of Albert Park means the track is ‘green’ and dusty at first and gradually improves over the weekend. With the re-introduction of slicks this year, the team will pay careful attention during free practice to the behaviour of the super-soft and medium compounds that Bridgestone will bring to this race – both of which must be used during the race. The high track temperatures usually experienced in Melbourne will play a role in determining which compound is preferred by the drivers.
Engine Performance
Melbourne offers a good test for engines with the V8s operating at full throttle for 66% of the lap. However, the secret of a good lap time depends not on peak power, but on good torque to help launch the car out of the slow corners that connect the succession of straights. This is particularly true of turns 14, 15 and 16, which are all tight, tricky corners.
