The London motor show will be revived in 2016 after an eight-year hiatus.
The reincarnated show will be held in one of the capital's parks, rather than in a traditional exhibition centre.
Prince Michael of Kent revealed plans for the show at the annual Guild of Motoring Writers awards, and hinted that it could rival more traditional motor shows in terms of its scale.
"I am delighted to tell you all that there are firm plans to bring the British motor show back in 2016 in Battersea Park," he said.
"It is right that London should have a motor show that ranks alongside those of Frankfurt and Geneva."
The prince said he hoped the event would secure the backing of many major car manufacturers.
