(September 3, 2011) INGOLSTADT, Germany —  With the electric-only powertrain of the four-seat A2 concept, Audi is offering another glimpse into the future of electric mobility at the 64th International Motor Show in Frankfurt in less than two weeks.

The Audi A2 concept is just a littler over 12-feet long and 5.5 feet wide, yet it manages to make a powerful impression on the street.

Its clean appearance concentrates on the essentials; all details are subtle but shaped for visual impact. The dark glass roof of the white-painted show car switches to transparency at the touch of a button.

With 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.

The dynamic light 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 driver and unlock the doors via gesture control. While driving, the dynamic light functions as a continuous side marker light. If the car’s turn 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. Like the entire interior, the dash panel has a light and clean look and intuitive controls.
