Grosjean didn’t start go-karting until the age of 14, in 3 years he had moved up to Formula Renault. His first year in the series, 2003, proved successful as he won 6 races and the Swiss title. In 2004, he competed in the French and the European Formula Renault Championships. One win and 4 podiums in the French series made him second-best rookie overall. The following year, he won the French Formula Renault after a dominant season in which he won 10 races. This success gave him a place in Formula 3 for Renault in 2006. Two wins gave him 13th place in the European Championship. Staying in Formula Three in 2007, he was rewarded with 6 wins and the title. Progressing to GP2 in 2008, he took the Asian title and won two races in the main series.
When Nelson Piquet Jr. was dropped from the Renault F1 team part way through the 2009 season, Grosjean was offered a drive for the team. However, his debut season didn’t go well – 13th in Brazil was his best race finish. Grosjean failed to make the Renault team in 2010, so raced in Auto GP, winning 4 races and becoming champion. He also competed in GP2, Le Mans and Spa 24-hours Races. Taking the GP2 championship in 2011, proved to the Lotus F1 team that he was worthy of a race seat in 2012.
Many incidents – such as the one in Spa when he took out Hamilton and Alonso – made his inexperience visible. The crash in Spa also resulted in a one race ban. However, three podium finishes proved to Lotus that he deserved to race for them in 2013. With six podium finishes in 2013, Grosjean finished 7th in the overall standings.
With an uncompetitive car for 2014, Grosjean failed to get a single podium and his best finish was 8th. This gave him just 8 points overall and proved to be one of the worst seasons in his career.
