After a lengthy three week break, with plenty of data from the new cars in Australia and Malaysia, the teams have had a chance to investigate, to analyse, and to upgrade. Whilst we're still in the fly-away part of the season, and upgrades to the cars are somewhat limited, most are hoping to bring some improvements to the Chinese Grand Prix weekend. Three practice sessions should see drivers testing out any new parts, and getting a feel for the track before qualifying on Saturday.
