The AMOC held the first open meeting on 27 October 1951, for what were dubbed "speed trials", but were actually a series of one lap sprint races.
Initially added to improve safety by slowing vehicles as they approached the pits, Russell bend was the scene of many accidents and was later altered to its present configuration.
On 23 September 2010, MSV announced that construction of the new infield section and track improvements would be finished in time for the 2011 motorsport season.
[7] The main development was the addition of a new one-mile infield section, after Sear Corner, which was replaced and renamed Montreal, in deference to it being modelled on the Circuit Gilles Villeneuve hairpin.
The final chicane before Senna Straight was also removed and replaced by an extension to Coram curve coupled with a new, tight, left-hand corner named Murrays.
The 300 track has been designed to bring international levels of racing to the circuit by gaining an FIA Grade 2 Licence.
[7] The 100 layout is made up solely of the new 0.980 mi (1.577 km) infield section and is mainly used for testing and as a race school.
Prior to the introduction of the 300 circuit in 2011, the official lap record stood at 0:56.095 (125.27 mph (201.60 km/h)) set by Klaas Zwart [de], during a BRSCC meeting in August 2007.
[10] The current 300 circuit lap record was set by Felipe Nasr from Brazil driving a Carlin prepared Dallara F308 in the 2nd race of the 2011 British F3 meeting.
