Another debutant in Frankfurt will be Audi’s A2 Concept all-electric – the company says the technical study will offer premium-standard space with plenty of room for four people in a vehicle that’s just 3.80m long.

Features include four individual seats, a dark glass roof that switches to transparency with the push of a button and a flat interior floorboard. Interior design cues include a centre console that’s attached to the driver’s seat, while the rear console extends forward between the two rear seats.

Storage space is to be had under the fold-up seat cushions, and there’s room between the rear seats for a city bicycle with its front wheel removed. The load area has two levels, with a frame with functional nets creating the upper level.

The colours and materials chosen for the interior help the impression of lightness and space along. Aluminium elements are to be found as highlights, and the large areas from the door top shoulders to the floor wear a new and innovative covering material made of polyurethane with a neoprene surface feel, and a ribbed material made from recycled polyester covers the central floor area.

The driver manages many important features via touch-control areas on the inside of the steering wheel. Two additional control surfaces fold up at the driver’s right when starting the vehicle. An open profile serves as the steering column, with a seven-inch display and two secondary displays located at its end.

Aside from the impressions of space and tech, the A2 Concept also works a fair bit of lighting into the scheme of things. There’s dynamic lighting, which runs below the edge of the window from the front to the rear of the car, essentially a band of light that contains a multitude of innovative, dynamic light functions.

Integrated approach sensors detect the owner and unlock the doors via gesture control. While driving, the dynamic light functions as a continuous side marker light. If the car’s indicator is activated, light impulses run throughout the entire band of light, and when braking, you get a red bar of light from the tail lights.

There’s also the utilisation of the next phase in LED technology, called a matrix beam; this is a package of LEDs and micro-reflectors generating a high-resolution and non-glaring high-beam light. Daytime running light-fibres frame the LED low-beam light module. Meanwhile, the rear fog light, which is produced by laser diodes, is seen as a beam of light in fog and projects a red triangle onto the road as a warning.
