T-wings sprout at Williams and Haas!

40

Williams and Haas rolled out their cars this morning with a T-wing mounted on top of the engine cover.

The aerodynamic device appeared on the Mercedes and Ferrari cars at their presentations last week, its function probably having to do more with optimising airflow to the rear wing rather than offering any sort of additional downforce.

Teams not running the T-wing are still in the process of evaluating its efficiency, as McLaren's Peter Prodromou confirmed at last week's MCL32 launch.

Toro Rosso's James Key also believed his team would test the device sooner rather than later.

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.
