Group GT1, also known simply as GT1, was a set of regulations maintained formerly by the Fédération Internationale de l'Automobile (FIA), for Grand Tourer racing.
[1][2][3][4] The class which was to become known as "GT1" was debuted by the ACO (Automobile Club de l'Ouest) at the 1993 24 Hours of Le Mans, under the name Group GT.
[7] Barth, an ex Le Mans winner, was manager of the customer competitions department at Porsche, Peter was a well-respected race promoter, while Ratel was an executive/investor in the Venturi GT1 project.
The car had no street legal version even built by the time the category collapsed in 1999, and shared only the instrumentation, front grille and the four headlamps with the normal CLK (C208).
[9] In 1998, realising that with the introduction of the updated CLK LM, and the 911 GT1-98, the F1 GTR could no longer be competitive, McLaren withdrew backing from the program, following BMW which had done so the previous year, in 1997, although two cars would still be entered by Parabolica Motorsports and Davidoff Classic.
