Audi has signalled its intent to battle BMW's upcoming i3 city car, confirming that its little A2 is on the comeback trail - and it's packing an electric punch.
Due to make its debut in concept form at the Frankfurt Motor Show this month, the next-generation Audi A2 will continue the themes of its predecessor: light-weight construction and an ultra-efficient powertrain.
But while the old and now six years-gone A2 got no more miserly than the 3.0 l/100km figures offered with the three-cylinder diesel '3L' variant, the new A2 will utilise an all-electric arrangement.
Details for the new A2's powertrain have not been revealed, but Audi promises both a full-electric model and an optional range-extending engine.
Audi has done away with the bubble body of the original A2, blessing the new model with a sharpened look that draws on the brand's latest styling language - particularly the recently-launched A1 and this month's Urban concepts.
The new A2 will offer seating for four, and the small cabin space will benefit from clever storage systems, including compartments beneath each seat.
Audi's designers also envision a unique internet connectivity interface in the centre of the instrument cluster, including connectivity with the inescapable social network, Facebook.
In concept form, the A2 features a new evolution of Audi's LED headlight technology, using micro reflectors to generate a high-resolution, non-glaring high beam.
At the rear, the taillights automatically adjust their illumination to suit the visibility conditions outside the car, and a new fog light projects a red triangle onto the road behind the car.
Measuring 3784mm long and 1689mm wide, the new A2 is only a little larger than its predecessor, but it is 61mm shorter than BMW's electric i3, and a whopping 322mm narrower.
The usual trick of a car's model name corresponding to its size has also been tossed out, with the A2 measuring 170mm shorter and 51mm narrower than the little A1.
