Follow the last day of pre-season testing 'LIVE' with F1i

Formula 1 teams will take to the Circuit of Catalunya for the very last time today in Barcelona before equipment is packed and sent on its way to Australia.

With one last chance to validate set-up settings or run through remaining programmes, it should be an action-packed day with extensive running for all.

Kimi Raikkonen, Max Verstappen, Sergio Perez, Romain Grosjean, Carlos Sainz and - last but not least - a very determined Fernando Alonso will all be entrusted with solo work for their respective teams.

Mercedes, Williams, Sauber and Renault will rotate as usual their drivers between the morning and afternoon sessions.

Ferrari started breathing down Mercedes neck yesterday and Sebastian Vettel beat Valtteri Bottas' fastest lap time to move to the top of the timesheet.

There won't be anything more than bragging rights to claim at the end of the day but one can assume that some mind games between the German and Italian camps could lead to a proper showdown before the day is over.

So join us to enjoy the action which starts at 9:00 CET (8:00 GMT), just head over to out 'LIVE ' timing and commentary page.

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.
