Preparations for the 2013 F1 season continue this week with the second pre-season test taking place at Catalunya.

Again running over four days, the test marks the first time that each of the eleven teams will run their 2013 spec cars, with Williams having launched the FW35 shortly before running got underway.

The first day in Barcelona not only marks the debut of the new Williams, but also the seasonal debut of Fernando Alonso, who is at the wheel of the new Ferrari for the first time having missed the Jerez test to continue his preparations for 2013 away from the circuit.
