The winter is finally over and F1 cars are back on track today for the first day of pre-season testing in Bahrain.
It is Lewis Hamilton's first official appearance for Ferrari, whilst old title rival Max Verstappen launches into a new season with Red Bull.
But what of reigning constructors' champions McLaren or Mercedes as it enters the post-Hamilton era?
We will get our first clues of how the season will shape up in Sakhir with eight hours of running.
Cars will be on-track between 10:00-14:00 and 15:00-19:00 local time, with this being 07:00-11:00 - 12:00-16:00 in the UK, which is three hours behind Bahrain.
