Luiz Razia makes his Formula 1 debut with Marussia in 2013 having been named in their line-up shortly before the start of the season.
After financial considerations forced the team to release the experienced Timo Glock, the 24-year-old Brazilian rookie made his debut in February's Jerez test just minutes after the deal was announced.
Unlike most F1 drivers, Razia's first taste of motorsport action was not in karting but instead driving off-road buggies in Baiano Autocross, where he finished as runner-up in his second season.
A switch to karts followed in 2004 and he made an immediate impact, winning three domestic Brazilian titles that season.
Razia stepped up the South American Formula 3 Championship in 2005, finishing sixth in the standings. He also contested Brazilian Formula Renault 2.0 that year finishing 10th.
After winning the South American F3 title in 2006, the Brazilian switched to the Euroseries 3000, finishing third in his debut season.
He made his GP2 debut in 2009 with Fisichella Motorsport, taking one win and one podium from 18 starts.
Razia was test driver for Virgin Racing in 2010, and had the same role at Team Lotus in 2011 as part of his role with the team's GP2 outfit.
2012 saw a switch to Christian Horner's Arden International squad and Razia enjoyed his most successful season since 2006 with four victories and nine podiums on his way to second in the Drivers' Championship.
