For over 20 years the British GT Championship has been an intrinsic part of the UK’s national motorsport fabric. But, having undergone a number of changes throughout those two decades, it’s difficult to envisage an era more competitive than the current GT3/4 format.

First organised by the British Racing Drivers Club in 1993, the BRDC National Sports GT Challenge (as it was then known) featured grids of wildly different machinery loosely grouped into vibrant classes comprising sportscars and saloons.

The term ‘British GT’ was first used in 1995 just as a new age of GT1 and GT2 cars was beginning to materialise. Indeed, the latter part of the 1990s would see some of the category’s most incredible and iconic cars, such as the McLaren F1 GTR, Porsche 911 GT1, Lister Storm GTL and Jaguar XJ220C contest British GT in the hands of top-line international racers and home-grown amateur talent.

But a GT racing revolution was about to take place, and Britain would be at the forefront. With GT1 becoming an increasingly distant memory and GT2 proving too costly the championship sought a fresh direction. New, balanced GT3 regulations had proven popular in Europe under SRO’s guidance and when the organisation was appointed British GT promoter in 2005 the same cars made their way across the Channel.

Indeed, since then British GT has re-established itself as the world’s foremost domestic GT series. GT4’s arrival and subsequent expansion currently sees two classes running on the same track at once, an important aspect of GT competition that enables a driver to prepare for international endurance racing, while the option to also field GTC entries remains a possibility.

Traditional British sportscar manufacturers have always featured heavily in the series: Lotus, TVR, Marcos, Darrian, Lister and, more recently, Chevron, Ginetta, Aston Martin, McLaren, Bentley and Lamborghini have underlined the championship’s unique British spirit.
