Start-Stop-System The start-stop system helps to reduce fuel consumption and CO2 emissions by switching the engine off when the vehicle is at a standstill. If the driver stops the vehicle at the traffic lights, for example, the system switches the engine off. The starting process is initiated as soon as the driver presses the clutch or releases the foot brake for the vehicle to move off again.
Audi drive select efficiency mode The Audi drive select efficiency mode improves consumption values and is characterised by the consumption-optimised application of the combustion engine and transmission shift programme. This encourages a more balanced driving style.This feature is available only on the Audi A4 35 TFSI.
