WATCH: Raikkonen gives new Alfa Romeo its track debut
Formula 1 pre-season testing kicks off on Wednesday when all 10 teams will be in Barcelona to see if they've got things right with their new cars, or whether they've got a lot of work to do before the first race of 2020 in Australia next month.
But before testing begins, a number of teams will have already run their cars as some opt to do a shakedown run of their own on a filming day, when they are limited to 100km.
Mercedes completed theirs at Silverstone on Friday, while at the same time Alfa Romeo were putting their 2020 challenger through its first laps at the Ferrari-owned Fiorano track, near Maranello in Italy.
Kimi Raikkonen got behind the wheel of the C39 as team mate Antonio Giovinazzi and new reserve driver Robert Kubica watched on from the garage.
Alfa are yet to officially launch the new car, and will do so on the morning of February 19 - the day the first test in Barcelona begins. In the meantime they ran the C39 at Fiorano in a special one-off snake-themed test livery.
