Audi has revealed a new traffic light recognition system which could reduce CO2 emissions by 15 per cent.
The technology uses Audi connect, the car's in-built WiFi connection, to establish a link between the car and the traffic light network via the town or city's traffic computer. By downloading the automated traffic light change sequences in the area, the car can then tell the driver the exact speed at which to travel in order to fly through the lights on green.
In addition to this, if the driver is already stuck at a red light, the system will calculate the time until the next green light is scheduled to appear and display this information as a countdown timer on the car's infotainment screen. The start-stop system will also ensure the engine switches back on five seconds before the green light appears.
Audi estimates that the system has the capacity to reduce CO2 emissions by up to 15 per cent and could save 900 million litres of fuel if used throughout Germany.
The system is now production ready and could be deployed across the entire Audi range, depending on the necessary relevant government legislation being passed.
