Audi has shown its compact A2 concept at the Frankfurt Show. The 4-seater boasts a sophisticated electric-only powertrain and by-wire technology, but it has also received plenty of attention for its creative and innovative lighting features.
With the A2 concept’s its headlights, Audi is presenting the next phase in LED technology, known as ‘matrix beam’. A package of LEDs and microreflectors generate a high-resolution and non-glaring high-beam light. Delicate daytime running light fibres frame the highly efficient LED low-beam light module.

Audi says that intelligent tail lights also adapt their illumination to the visibility conditions. The rear fog light, produced by laser diodes, is seen as a beam of light in fog and projects a red triangle onto the road as a warning.
But the obvious design feature is the ‘dynamic light’ that runs below the edge of the window from the front to the rear of the A2 concept – 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 also functions as a continuous side marker light. If the car’s indicator is activated, light impulses run throughout the entire band of light.
In addition, a red bar of light flows forward from the tail lights when braking and demonstrates the strength of the brakes intuitively for other road users.
The dynamic light is also located in the cockpit area of the show car, structured in two separate arches.
