The new, third-generation Mini will be revealed on 18 November, a date which also marks the 107th birthday of the original Mini designer Sir Alec Issigonis.
Mini's plant in Oxford will host the world premiere of the latest generation of the car, which will also be built at the site.
Pictures showing the new car undisguised have already been circulated on the internet. The pictures, taken during a photoshoot for the car, show notable design changes at the front end.
A more prominent front grille, larger headlight clusters and a more angled rear roofline help to give the new Mini a more distinctive look than the second-generation model.
A range of 1.5-litre petrol and diesel three-cylinder engines developing between 120 and 190bhp will power the car, while higher-powered 1.6-litre turbo options producing up to 280bhp are expected to be released in new Cooper S and JCW versions. Transmission options will come in the form of the standard six-speed manual or eight-speed automatic.
