This is a concept design for the next Mini by Sonny Lim, who previously worked at BMW DesignWorksUSA.
Its between the current Mini and the now dead Rocketman concept in size, and is aimed to be a more basic car than the current car, lightweight (so more eco friendly), no plastic and chrome tat, but still essentially recognisable as a Mini.
As someone who doesn't like the current or previous 'New Mini', I like this. It's recognisable as a Mini with the general shape, lights and grille, but its a simpler looking car without the retro chrome bits and pieces.
I hope the real new Mini next year can be anything close to looking as nice as this.
