The first official test of the World Touring Car Championship begins on Friday (13 February) in Barcelona.

It will be the first time the teams will be participating together in a collective test, with Citroen Racing - which features an unchanged driver line-up - looking to continue its dominance from the 2014 season when it wrapped up 19 of 23 races.

Though it hasn't formally revealed its drivers for 2015, Honda Racing is expected to continue with Gabriele Tarquini and Tiago Monteiro, while Honda Racing Team Sweden is set to swell the number of customer Civics on the grid alongside Proteam and possibly Norbert Michelisz's Zengo Motorsport.
