The 2012 F1 season gets underway at Albert Park with the opening free practice session. Ninety minutes for the teams to see how their cars stack up against the competition, and how their drivers cope with the new machinery underneath them. Our first glimpse at Kimi Räikkönen's official comeback, Sebastian Vettel's first practice as a double world champion, and Vitaly Petrov's first stint as a last minute Caterham driver. It's all kicking off in Melbourne, and Free Practice heralds the start of something fabulous.
