The stunt was created for the new television show James May’s Toy Stories to be shown on BBC2 later this year.
May and 300 volunteers used approx 20,000 separate sections of track to recreate the 2.953 mile circuit.
Scalextric shattered the current record for a slot car track, which was replicated in Berlin on October 2007, by 2,189.82 metres.
Once the mammoth challenge was completed, two Scalextric model cars, a maroon Aston Martin DBS and a Mercedes-Benz SLR McLaren roared around the newly created track.
Paul Chandler, Scalextric marketing manager, commented: “Many doubted whether this could really be done but we are delighted James and the team have pulled it off.
"To recreate the Brooklands circuit, the birth of Motor racing, was a dream for James and Scalextric fans in general. This shattered the previous world record and a lot of hard work went on behind the scenes to make this all possible."
