Audi has released some new details about their traffic light recognition technology.
Dubbed Audi Online traffic light information, the system connects the car to the traffic light network via a central traffic computer. Once a connection is established, the Driver Information System will display the speed the driver needs to achieve in order to get a green light at the next intersection. If the driver is already waiting at a red light, the display will show the remaining time until the light turns green. More importantly, the system will automatically start the car's engine - on models equipped with start/stop technology - five seconds before the light turns green.
Audi says the system is "production ready" and could be equipped on every model they sell. If this were to happen, drivers would save approximately 900 million liters (237 million gallons) of fuel in Germany alone. The company also says CO2 emissions would be reduced by up to 15 percent.
