Marussia has confirmed that they will be present at the first test of 2014 next week.
The MR-03 is set to make its track debut on Tuesday morning at Jerez in southern Spain.
Marussia has retained Jules Bianchi and Max Chilton for a second successive season.
'[We're] planning to get straight down to the business of testing & looking forward to running all the new elements,' Marussia posted on their official Twitter account.
Marussia's presence at the first test of the season means that only Lotus is set to miss out on the first four days of track running.
