With new cars and regulations, the F1 teams are keeping things close to their chests before the 2017 season starts today in Melbourne (start time 6.00am).

Mercedes and Lewis Hamilton will very likely be leading the pack, but there’s hope in some quarters that this year’s tournament can inject some competition into the arena.

Can Red Bull and Australian driver Daniel Ricciardo – rumoured to have been approached by Mercedes – be the team to take on the giants?
