Marussia named Max Chilton to complete its line-up for the 2013 season making the 21-year-old the fourth different driver to partner Timo Glock in as many years.
Having joined the team last year in the role of a test and reserve driver during the Japanese Grand Prix weekend, the Briton took part in one practice session later in Abu Dhabi. He had also participated in the young driver test at Silverstone earlier in July.
“I am very fortunate to have spent the last six races with Marussia as a reserve driver, which means that instead of a standing start, I am already up to speed and at ease with the people, the culture, the systems and of course, the 2012 package,” said Chilton who will be one of the four British drivers on the grid next season.
“During the period since the Japanese Grand Prix, I have watched at very close quarters the incredible commitment and determination to succeed that saw everyone in the team pushing until the very last race. I feel very lucky to be able to embark on my F1 racing career with this group of people.
“Pre-season testing is just a few weeks away, so my focus now is to continue my physical preparation whilst spending as much time as possible working with the technical team to help develop the car I will drive in my debut F1 season,” he added.
Chilton has come through Marussia's young driver program, with the team saying "his development has been rapid in all aspects."
Lewis Hamilton, Jenson Button and Paul Di Resta are the other British drivers in F1.
