Spanish bank Santander released an F1 driver's point of view CGI film back in 2012 of an imagined 5.156-kilometre circuit around London.
The route takes in some of the Capital’s most famous landmarks and was produced after a detailed feasibility study for such a race was carried out.
The lap would start in The Mall and cars would reach speeds of 180mph on the 3.2-mile circuit, with drivers racing past sights such as Buckingham Palace, Big Ben and Trafalgar Square.
The route also features perhaps one of the most audacious corners seen on an F1 track, as 24 cars steer their way from Trafalgar Square into Admiralty Arch.
