They'll be plenty of time for some well deserved play and rest in the coming weeks, but for now Lewis Hamilton is back in action in Abu Dhabi as he samples Pirelli's 2017 tyres.

Less than fourty-eight hours after losing the title to team mate Nico Rosberg, Hamilton was called upon by Mercedes to assume tyre testing duties initially assigned this morning to Pascal Wehrlein.

It's not clear why the German manufacturer decided to change its line-up and split its testing workload but perhaps it felt compelled to call upon Hamilton as a bit of retribution for balking at team orders during Sunday evening's showdown in the closing stages of the race.

Mercedes will run Hamilton in the morning and Wehrlein this afternoon, while Ferrari and Red Bull will also take to the track with Kimi Raikkonen on hand, and Daniel Ricciardo and Max Verstappen.

Pirelli's next extensive test is scheduled on February 27 in Barcelona, where all 2017 cars will appear.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
