Audi has unveiled its new DTM championship car at the 2014 Geneva auto show with an almost totally new aero package. Will anybody be looking at anything else?

    • Audi traffic lights info online
    • 15% drop in CO2 emissions
    • Drivers told speed needed to green
    • Prototype showcased in Audi A6
    • Works with Audi Connect and MMI

Audi has advanced traffic-light recognition technology to make urban driving far more fluid.

The system harnesses in-car internet via Audi Connect to link the car and the traffic-light network via the traffic computer in each town.

It quickly assimilates the area's automated traffic-light change sequences and tells the driver the speed required to pass through the light on green. It displays a visual aid using red, amber or green icons (See image).


If the driver is waiting at a red light Audi Connect will count down the time to green - a timer on the DIS will appear. The system also interacts with the cars's stop/start function to turn on the engine five seconds before green.

Audi said: "Online traffic-light interaction has the potential to reduce CO2 emissions as much as 15% and could save about 900-million litres of fuel if it were to be deployed throughout Germany."

The system is production-ready and could be fitted to every Audi subject to the government legislation.


Testing is under way in Berlin where 25 Audi customers are driving cars that can link to 1000 traffic lights there.
