The 23-year-old Brazilian, runner-up in last year’s GP2 championship, will mark the news by testing Marussia’s newly-launched MR02 car at Jerez on Wednesday.
The 2013 vacancy, now filled by Razia, opened up recently when Marussia split with Timo Glock, citing the need for a sponsored driver.
“Together with Max (Chilton), we are fielding a young but incredibly ambitious pairing and we look forward to seeing what they can achieve,” said team boss John Booth.
Razia was the reserve driver for the team in 2010, when it was known as Virgin Racing.
“It is fantastic to be back with the Marussia F1 Team and with pretty much the same group of people I worked with back in 2010 when I was Reserve Driver,” said Razia.
“Having been in that position, I know this Team rewards determination and success in its young drivers, the intention of its Programme being to school the next generation of racing driver. I am very proud to take the step up to a Formula 1 race seat, particularly with the Team I began this journey with, since they helped show me what it takes to progress to the highest level. The past two seasons in GP2 have been all about proving that I have what it takes and that I’m ready.”
“This coming season will be all about rewarding the faith the Team have shown in me. I am looking forward to beginning that process in Jerez where we are testing the MR02 for the first time. I am also looking forward to the first race in Melbourne and I’m excited to be racing alongside Max, who I competed ‘against’ last season. This is an important year for the Marussia F1 Team in terms of maintaining the momentum from a very positive 2012 season. I look forward to making a valuable contribution to that.”
Razia becomes the second Brazilian on the 2013 grid and the fifth rookie.
