FIA gives the green light to Mercedes wheel design

40

The FIA has no issues with the innovative wheel and rim design fitted by Mercedes to its W09 after the concept was called into question by Ferrari.

The intrigue surrounded a series of holes in the Mercedes' rims that could have been considered as part of a movable aerodynamic device, and therefore in breach of the regulations.

The design followed a similar idea used by Red Bull back at the 2012 Canadian Grand Prix and which was ultimately deemed illegal.

Mercedes still expecting Ferrari to 'fight fiercely' for every point

However, Mercedes' design was put to the scrutiny of the FIA at Ferrari's, the Scuderia suspecting the W09's wheels, and its subsequent brake and suspension changes since Spa, may have played a significant part in the car's recent gains.

After a thorough analysis, the governing body has concluded that Mercedes' wheel concept is perfectly legal.

It's all fair game and par for the course between the two arch-rivals, with Mercedes questioning earlier this year Ferrari's advanced dual-battery system embedded in the hybrid unit of its SF71-H.

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.
