One final epic battle between Senna and Prost

Thirty-one years ago,F1 legends Ayrton Senna and Alain Prost enjoyed their final on-track battle against each other.

At the time of the encounter at the 1993 Masters Karting at Bercy, near Paris, Senna and Prost were in the process of rekindling their relationship.

But when they came to race each other in the two-day karting charity event, their competitive spirit was just as sharp-edged and honed as it had been during their most epic fights in F1.

Prost prevailed in the main heat as Senna's kart was hit with a mechanical issue. But the real winner that day was the camaraderie and friendship that drew the two men together once again.

In the following months they talked frequently, with Senna confiding in his old nemesis about his new life at Williams, Prost's former team.

And then came the tragic weekend at Imola...

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.
