Formula 1 returned to action on Wednesday as teams tackle the first of three final days of testing before they head of the Melbourne, Australia for the opening race of the season.
Robert Kubica would end up topping the timesheets and all
but one driver of the full field would get behind the wheel.
Plenty of the teams continued to run aero rakes – some of
them were massive – and plenty of flo-vis paint was also on display.
Here are some the best shots of the first day of the final pre-season test from the Circuit de Barcelona Catalunya.
