Previously codenamed 'Junior', the stylish new three-door will make its public debut at the Paris motor show in October.
The Adam will be priced to compete with both rivals, and come with a host of personalisation options, including colour and trim choices.
Sources at Vauxhall claim that the Adam will have 'muscular and sporty' styling and not share the looks of any other small Vauxhall. Something thats borne out by the official spy shots the company has released.
Several engine options will be on offer, including a newly developed 1.0-litre three-cylinder engine.
