Caterham has revealed its 2013 F1 car at Jerez this morning. The CT03 will begin pre-season testing today with a new brace of drivers: Charles Pic has moved from Marussia while former Caterham test pilot Giedo van der Garde has been given a permanent drive.

After finishing tenth in the Constructors' championship last season, Caterham will hope to outperform Marussia again. However, this could prove even more of a challenge in 2013 given the loss of experienced drivers Heikki Kovalainen and Vitaly Petrov. Moreover, the CT03 is an evolution of last season's car, rather than a clean-sheet design.

The first stint of pre-season testing finishes at Jerez on Friday. The teams move to Barcelona on 19th February.
