R.Grosjean
Romain Grosjean, like his 2012 Lotus teammate Kimi Raikkonen, returned to Formula 1 after a gap of two years.
The Frenchman, who is a chef and has been a banker, has his task cut out again as he partners the 2007 world champion after his first stint in F1 saw him teamed up with another title holder; Fernando Alonso.
But this time, Grosjean is well prepared clinching championships in the GP2, GP2 Asia and the Auto GP series' as a part of his preparations to return to F1.
Chucked into the highest echelons on motorsport in 2009 to take Nelson Piquet Jr's seat and paired with a double world champion, Grosjean failed to impress that year and was promptly replaced for the following season.
But he worked hard enough to be mark his return thanking his detractors for making him stronger as he sets out to prove them wrong.
Grosjean was the team's, which was called Renault, test and reserve driver in the 2011 season taking part in Friday practice sessions before he was promoted to a race seat for 2012.
