- New technology set to reach the European market later this year
- Individually controlled LEDs for high-precision lighting
- Audi has been leading the way for many years with an array of innovations
Ingolstadt, June 28, 2013 - Audi is now building on its lead in the domain of lighting technology with a world first: the Audi Matrix LED headlights will make their debut on the new A8, which will appear in Europe at the end of 2013. Audi, the technology leader in this field, is thus opening a new chapter in automotive lighting.
Audi Matrix LED technology splits up the LED high-beam headlights into numerous individual, small diodes working in conjunction with lenses or reflectors connected in series. Managed by a responsive control unit, they are activated and deactivated or dimmed individually according to the situation. This means they always supply high-precision illumination and achieve the maximum possible light yield without needing a pivoting mechanism.
In the new Audi A8, each headlight comprises 25 high-beam light-emitting diodes, arranged in groups of five per reflector. When the light switch is set to "automatic" and the high-beam headlights are on, the system is activated from 30 km/h on highways and from 60 km/h on city streets. The Audi Matrix LED headlights produce a quality of light with a special crystalline sheen. By day, too, they have a very attractive and distinctive look, which is reinforced by the new appearance of the daytime running lights.
As soon as the camera in the A8 detects oncoming vehicles, the Audi Matrix LED headlights dip the relevant sections of the high-beam headlights. The system operates with such precision that it blanks out light that would shine directly at oncoming and preceding vehicles, but continues to cast the high beams with full power on all other zones between and beside them. The closer an approaching vehicle gets, the more LEDs are deactivated or dimmed. When there is no more oncoming traffic, the high-beam headlights then resume full power, including the sections that had previously been off. The light that the driver sees is always bright, homogeneous and much more effective than that produced by competitors' mechanical dipping systems.
Matrix LED technology offers fascinating potential in many different respects, in terms of the number of individual LEDs, their arrangement, and the size and design of the headlights. One of its safety functions in the Audi A8 involves providing what are known as marker lights: these team up with the optional night vision assistant to mark detected pedestrians. When it detects a person in the critical range in front of the car, individual LEDs flash at them rapidly three times in succession, picking out the pedestrian clearly from their surroundings and alerting both the pedestrian and the driver.
The light-emitting diodes of the Audi Matrix LED headlights also perform the cornering light function; they displace the emphasis of the beam in the direction of the bend. By calling on predictive route data supplied by the MMI navigation plus, they do so shortly before the steering needs to be turned. Another function in the new Audi A8 is the turn signal with dynamic display: the LEDs in the turn signals flash in blocks at 150 millisecond intervals in the direction that the driver intends to turn.
Audi leads the way in automotive lighting technology and the brand has repeatedly masterminded crucial advances over the years. Here are just the main world-leading innovations:
1994: second-generation xenon headlights in the Audi A8
2003: adaptive light in the Audi A8
2004: LED daytime running lights in the Audi A8 W12
2008: full-LED headlights in the Audi R8
2010: connectivity between the headlights and navigation data in the Audi A8
2011: homogeneous LED rear lights design in the Audi A6
2012: turn signal with dynamic display in the Audi R8
2013: full-LED headlights for the compact class
2013: EU validates LED technology from Audi as an eco-innovation, the first manufacturer to be certified for this technology
The advantages of these Audi innovations include a better quality of light, which also means improved safety. As expected from Audi, these attractive lights are also highly energy efficient. A wide range of customers can reap the benefits – the LED headlights, for example, are available from the compact A3 car line upward. Also the Le Mans sports cars of Audi – the R18 e-tron quattro that has just retained the title at the 24 Hours of Le Mans – have been fitted with LED headlights for a number of years; on the straight, they illuminate the racetrack over a distance of about one kilometre.
Audi intends to extend its lead step-by-step. The automotive lighting of the future will respond with even greater precision to the surroundings and interact with it in diverse ways. It will have all-electronic control and be even more attractive thanks to new dynamic functions.
The Audi Group
The Audi Group delivered more than 1,455,100 cars of the Audi brand to customers in 2012. In 2012, the Company posted revenue of €48.8 billion and an operating profit of €5.4 billion. Audi produces vehicles in Ingolstadt and Neckarsulm (Germany), Gyor (Hungary), Changchun (China) and Brussels (Belgium). The Audi Q7 is built in Bratislava (Slovakia). In November 2012, CKD production of the Audi Q7 was added to the existing Audi A4, A6 and Q5 manufacturing operations in Aurangabad (India). At the Brussels plant, production of the Audi A1 has been running since 2010, while production of the new A1 Sportback began in 2012. The Audi Q3 has been built in Martorell (Spain) since June 2011. The Company is active in more than 100 markets worldwide. AUDI AG's wholly owned subsidiaries include AUDI HUNGARIA MOTOR Kft. (Gyor, Hungary), Automobili Lamborghini S.p.A. (Sant'Agata Bolognese, Italy), AUDI BRUSSELS S.A./N.V. (Brussels, Belgium), quattro GmbH in Neckarsulm and the sports motorcycle manufacturer Ducati Motor Holding S.p.A. (Bologna, Italy). Audi currently employs more than 68,000 people worldwide, including around 50,000 in Germany. The brand with the four rings plans to invest a total of €11 billion by 2015 – mainly in new products and the expansion of production capacities – in order to sustain the Company's technological lead embodied in its "Vorsprung durch Technik" claim. Audi is currently expanding its site in Gyor (Hungary) and will start production in Foshan (China) in late 2013 and in San José Chiapa (Mexico) in 2016.
Audi has long been fulfilling its social responsibility on many levels – with the aim of making the future worth living for generations to come. The basis for Audi's lasting success is therefore formed by environmental protection, the conservation of resources, international competitiveness and a forward-looking human resources policy. One example of AUDI AG's commitment to environmental issues is the Audi Environmental Foundation. Within the context of "Vorsprung durch Technik", which extends far beyond its products, the Company is directing its activities toward a major goal – comprehensive CO2-neutral mobility.
