London (CNN) -- The first race in Melbourne is just around the corner and Formula 1 teams are gearing up for a season which promises to be as technical as it is tactical. Cars converge in 2013 With the sport's governing body, the FIA announcing minor changes to technical regulations, teams have mostly tweaked their cars in 2013, says F1 journalist Craig Scarborough. "There are big rule changes coming up next year so the teams are trying to balance their resources. They don't need to completely go out and redesign their chassis, it's just a few little features that they want to incorporate. No one has produced a massively different or a massively exciting car this year," he said.
