The biennial motor show, which is open to the public at ExCel in London Docklands from 20-30 July, is returning to London after an absence of 30 years, having been held in Birmingham.
Motor show spokeswoman Kirsty Adams said: "This is the first time London has seen a celebration of the automobile which is such an essential part of our lives.
