Kubica calls it a day with 100 laps under his belt

Robert Kubica concluded his first day of running at Yas Marina with Williams' FW40 with 100 laps and a fairly irrelevant eighth fastest time.

The Pole focused on short performance runs while sampling a range of Pirelli tyres before undertaking longer stints, recording a best lap of 1m41.296.

The time, which was about 3.5s off Kimi Raikkonnen's fastest lap, was perceived as irrelevant given the specific nature of tyre testing, when drivers test a diversity of rubber and settings.

Lance Stroll took over for the afternoon but Kubica will be back behind the wheel on Wednesday afternoon following a test in the morning by Sergey Sirotkin.

Kubica's test was looked over by Williams' top engineering brass made up of Paddy Lower and Rob Smedley, but part-time manager Nico Rosberg was also present to oversee the run.

The test was free of any drama and Williams was reportedly pleased with its driver's performance and feedback.

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.
