The championship has a proud heritage dating all the way back to 1957. Ken Gregory, best known for being the manager of former British Formula One racing driver Stirling Moss, felt that there was a gap for manufacturers to exhibit their new and increasingly popular ranges of passenger cars post-World War 2. Gregory suggested to the British Racing & Sports Car Club, of which he was secretary, that running a championship alongside the club's 500cc Formula 3 could boost the profile of saloon car racing.
The first race with scores counting towards the points table took place on Boxing Day 1957, with the very first BTCC coming to a conclusion in 1958.
Over the years, the rules and regulations of BTCC have shifted and changed, but providing current production cars with a platform to compete has always been the rationale behind the championship.
