The race was originally organised by Britcar. The 2009 race was shortened to 500 miles due to the recession. In 2011 the race used the new arena section for the first time. In 2010 the race continued to use the bridge section that the race had used in previous years despite other racing series already switching to the new layout. The 2013 edition was shortened to 1000 km. For 2015 the race was called the Dunlop 24hr at Silverstone for sponsorship reasons.[1]
Many big name teams have taken part in the race such as Rollcentre Racing, Jet Alliance Motorsport and Duller Motorsport. As of the end of the 2016 race, Duller Motorsport and Rollcentre Racing are the only teams that have won this event more than once.
Factory effort teams have also attempted it such as Ginetta, Mazda and Nissan.
In 2007, Top Gear took part in this race using a diesel BMW 3 series for a Top Gear Challenge. They finished the race, third in class, ahead of one of their rival teams who were also competing with a diesel BMW 3 Series.[12]
In 2012, a team of ex-servicemen took part under the Mission Motorsport banner in a Nissan 370Z. They finished in 17th overall, scoring a top ten class result.
In 2015, the Ginetta Nissan LMP3 took its debut 24 hour race start with the factory Team LNT squad. Among the driver roster was six-time Olympic champion Sir Chris Hoy. 2015 also marked the first year for a female scoring outright victory; Jamie Chadwick aboard the #35 Beechdean Aston Martin.
Since 2016, the race is restricted to touring cars and 24H-Specials.
