A clearer picture of the 2018 Formula 1 season will only form in Melbourne - and perhaps not even then - but there were already numerous conclusions to be drawn as pre-season testing wrapped up in Barcelona.

Of the 7978 laps officially logged, the ones during the second test are the key ones and have set the key storylines for the early races of the season.
