C teaser image revealed

Audi has revealed a teaser image of its Audi A1 - a rival to premium superminis such as the Mini.

The image is part of a teaser video where a graffiti artist spray paints an image of the car on to a wall.

The A1 will be revealed at the Geneva motor show next spring, before going on sale in the autumn. Prices are estimated to start at around £14,000.

Audi A1 - the clues we've seen so far
We have already been given plenty of clues to what the A1 will look like in the metal. The A1 Metroproject concept car was revealed at the Tokyo motor show two years ago, and a year later a five-door 'Sportback' version was shown at the Paris show.

Both of these concept cars were petrol hybrids, although the first production cars will be more conventional. While engines have yet to be confirmed, they will be from the existing VW line-up, which means the 1.2 TSI and 1.4 TSI turbocharged petrol engines look certain to feature. A hybrid will follow a year or so later.
