Justin Wilson joined the Champ Car World Series with Conquest Racing in 2004, following a 2003 season in which he competed in the Formula One World Championship. Wilson drove the first 11 races of the season for Minardi before joining the Jaguar team for the German Grand Prix, which was Round 12 of the 16-race season. He earned his first World Championship point in the season's penultimate event with an eighth-place performance at the United States Grand Prix.
Wilson won the 2001 FIA International Formula 3000 championship on the strength of three race victories, six second-place finishes, and one third-place run, establishing the series record for most points in a single season (71) and podium finishes (10) in a dominating performance. In fact, Wilson broke records established by 1999 Champ Car World Series champion and former Formula One front-runner Juan Pablo Montoya, who won the 1998 F3000 title.
In 1998, Wilson won the Formula Palmer Audi championship with nine victories, 10 fastest laps, and four pole positions. After placing fourth in the inaugural Telefonica World Series by Nissan in 2002 with two victories, two pole positions and a total of eight podium finishes in the Spanish-based series, Wilson participated in a Champ Car test with Newman/Haas Racing and was in contention for the team’s vacant seat before turning his attention to Formula One for 2003.
Upon joining the Champ Car World Series, the Briton adapted extremely well.
Following a successful rookie campaign that saw him capture two top-fives and eight top-10s with Mi-Jack/Conquest Racing, Wilson moved to RuSPORT in 2005 – where he scored two victories and finished third in the championship standings.
The 2006 campaign saw him improve once again, netting one victory, five runner-up finishes, seven podium finishes, 10 top fives and 11 top-10s in 13 starts. Those results propelled him to second in the championship, losing out to three-time champion Sebastien Bourdais by 89 points.
In 2007, Wilson again finished second in the points behind Bourdais. He won one race and two poles, and scored nine top-five and 12 top-10 finishes.
When the Champ Car World Series merged with the IndyCar Series, Wilson joined the Newman/Haas/Lanigan Racing effort in the series. He finished 11th in the standings in his first year and scored his first IRL career victory at The Raceway at Belle Isle.
Wilson joined Dale Coyne Racing for the 2009 season. He gave the team its first IndyCar Series victory at Watkins Glen. En route to a ninth-place finish in the standings, Wilson recorded three top-five and seven top-10 finishes.
For the 2010 season he'll drive for Dreyer & Reinbold Racing.
