EU Validates Audi LED Technology as Eco-Innovation

INGOLSTADT, GERMANY – April 12, 2013: LED headlights from Audi verifiably improve fuel economy. That is why the European Commission is now certifying this technology.

Lighting systems have a tremendous effect on an automobile’s fuel economy. Conventional halogen units, for example, consume over 135 watts of power in their low-beam headlight mode. By comparison, LED headlights from Audi operate with significantly better energy efficiency – the low-beam lights only consume around 80 watts.

The EU Commission has measured the fuel savings achieved by LED headlights from Audi – testing the low-beam headlights, high-beam headlights and license plate light in dynamometer testing. In the ten NEDC cycles that the Audi A6 ran through, CO2 savings were found to be over one gram per km (1.61 g/mile). As a result, the EU Commission has officially identified the LED headlights as an innovative technology for reducing CO2 emissions. Audi is the first car manufacturer to be certified for this technology.

LED daytime running lights made their debut in the Audi A8 W12 back in 2004. Then, in 2008, the R8 sports car became the world’s first car to feature full-LED headlights. Today, this high-end lighting system is available in five model series: the R8, A8, A6, A7 Sportback and A3.

Audi designs the LED headlights very differently for different models. On the A8, for example, 76 light-emitting diodes are used per unit. On the Audi A3, 19 LEDs operate in each headlight to generate the low-beam and high-beam lights; they are supplemented by a module for the all-weather and cornering lights as well as a light guide for the daytime running lights, side lights and turn signals. Besides improving energy efficiency, LED headlights also offer safety and comfort benefits. With a color temperature of around 5,500 Kelvin, their light resembles daylight and hardly causes any eye fatigue. The LEDs are maintenance-free and designed to last the life of the car.
