The company was established in Madrid in 1998 by former driver Jesús Pareja, a successful competitor in GT and sportscar racing during the 1980s and 1990s. He claimed victories in the 1000 km of Jerez (1986) and Suzuka (1994), as well as the 4 Hours of Jarama and Paul Ricard (1994). He also finished 2nd overall in the 24 Hours of Le Mans in 1986 and the 24 Hours of Daytona in 1994, and won the GT class at Le Mans in 1994.
From 1986 to 1991, he competed in the World Sportscar Championship as a member of the highly successful Brun Motorsport team, the Swiss outfit that was crowned World Champion in 1986.
The first series created by GT Sport was the Spanish / IBER GT Championship in 1999, followed in 2000 by the Spanish F3 Championship, which took the helm from the F.Toyota 2000, which together with the F.Toyota 1300 had joined the GT Sport platform in 1999. The new Spanish F.3 series kept Toyota engines and adopted new, modern Dallara chassis. It ran in such form until 2008, with direct technical and marketing support of Toyota until 2006.
During that period, GT Sport also organized in Spain a number of mono-brand trophies on behalf of manufacturers such as SEAT, Hyundai, Peugeot and Mini. The company’s capabilities and expertise has also been at the service of major international series and FIA championship, as the company was regularly called to serve as the local promoter in Spain and Portugal for events of the World Touring Car Championship (WTCC).
