The prospects of another British International Motor Show look bleak after the Society of Motor Manufacturers and Traders said the "world had moved on".
Paul Everitt, SMMT chief executive, said: "The British International Motor Show had a limited role in generating a return on investment for the car industry in Britain. Lots of people go, but it has no real benefit for carmakers.
"Consumers liked the Excel show in London, but we take the view that without the cost of a single industry show we can support other events."
These could include two Goodwood motoring festivals and a free Motorexpo at London's Canary Wharf.
