After just one day's break after winning the season finale on Sunday evening, Mercedes driver Lewis Hamilton is back at work.
Taking to the same track that saw his teammate win the 2016 Drivers Championship, Hamilton is joined on the Yas Marina Circuit by the two Red Bull Racing drivers, Daniel Ricciardo and Max Verstappen while Kimi Raikkonen is also on duty for Ferrari.
The four drivers are putting the new wider 2017 Pirelli tyres through their paces for Tuesday only, Hamilton's first time trying out the new rubber after missing an earlier test due to injury.
Lewis will only be on track for half the day with Pascal Wehrlien taking over the test for the afternoon.
