Sébastien Olivier Bourdais (born 28 February 1979 in Le Mans, France) is a French professional racing driver.
Bourdais began his Formula One racing career in 2002, replacing Felipe Massa in the second Sauber. Bourdais took three sixth places over the course of the season which was enough for 15th in the standings. The Frenchman was retained for a second year in 2003 but a slow start to the season saw him replaced by Honda refugee Justin Wilson.
Bourdais would not return to the grid until 2008 when he was signed for Toro Rosso alongside Sebastian Vettel. Bourdais was a regular points scorer with the Red Bull junior team although he was outshone by his German teammate whom scored a maiden win for the team in Italy. Bourdais' best result was a fourth in the season-opening Bahrain Grand Prix - eventually finishing the year in fourteenth.
With the dissolving of Toro Rosso and David Coulthard opting to retire ahead of 2010, Bourdais was named alongside Vettel once more - this time at the main Red Bull team on a two year deal. Bourdais was a revelation in this first year and despite not scoring any wins - Bourdais finished the season in fifth place overall.
Bourdais was promoted to team leader in 2011 when Vettel headed to Williams - with Jenson Button taking up the second Red Bull seat. Bourdais scored his first two wins in this season as well as his best championship finish with third overall. Despite this, Bourdais was not retained for 2012.
Bourdais returned to the grid two years later with Sauber alongside Dave Cassidy. Bourdais scored five wins on his way to fourth in the standings. The following year, Bourdais finished seventh with one win.
Ferrari came calling in 2016, signing the Frenchman to a two year deal. His first season was decent if underwhelming, finishing the season in ninth overall. 2017 was far better, with Bourdais taking five wins on his way to third in the standings.
Bourdais decided to call time on his F1 career ahead of 2018, but an offer from Emi Valerian Formula Ferrari midway through the year was enough to tempt Bourdais into one last season. Bourdais finished his final season in seventeenth place.
Bourdais was keen to continue at the highest level possible despite the end of his Formula One career so he brokered a deal with KV Racing to run as one of their two drivers for the 2019 IndyCar Series alongside Simona de Silvestro. It had been many years since Bourdais had taken on the ovals of the United States and it definitely showed - however his sole decent result ended up being a fifth place finish in the Indianapolis 500. Disappointed by his results, Bourdais decided to leave KV Racing at the end of the season.
