- —Mater driving in London
London is the capital city of the United Kingdom. The town has a rich past, and it still has numerous historical buildings and monuments. It hosts the last race of the World Grand Prix.
This race track passes, as for the two other races, on the streets of the host town, in this case notably borrowing the Mall, and getting in front of Buckingham Palace.

- The dome of St. Paul’s Cathedral is shaped like a car’s differential gear casing.
- Big Ben is renamed Big Bentley in Cars 2, and is made up of Bentley grilles and hood ornaments. Production Designer Harley Jessup added that "In order to make it fit into the Cars world, we scaled it up about 250 percent — even the clockworks, which would actually fit in a conference room, were scaled up by at least 50 times their normal size."
- The Latin inscription below the clock dial on Big Bentley reads “God Salvage Crown Victoria the First” – a reference to the Ford Crown Victoria.
- The Lucite canopy over the Queen’s platform is based on the canopy built for Prince Charles’ investiture as the Prince of Wales.
- The architecture of the race pits in London is based on Landau bars, a design feature used on cars to simulate the look of a convertible.

- A road is named "Lasseter Way".
- In the movie, Tower Bridge is named Tyre Bridge.
- The knighting room is decorated with "car-ified" ancient paintings, featuring notably a battle of sailing ships.
- The tie-in storybooks for some reason showed Holley Shiftwell's escape from Big Bentley as showing her smashing apart an entire clock face. In the actual film, Holley only smashed away the "5."
- In the film, Trafalgar is renamed Trafalgear, and Piccadilly Circus is renamed Petroldilly Circus.
- In the comic, Acer and Grem were thrown into a garbage truck instead of Ye Left Turn Inn.
