The best way to make efficient engines even more economical: switching them off.
Standard at Audi: the start-stop system that helps the driver to save fuel and thus reduce CO2 emissions. When the car has come to a complete standstill, the gear lever has been moved to neutral and the driver has released the clutch pedal, the system automatically shuts down the engine. In the stop phase the driver information system displays a “Start-Stop” symbol. The engine starts again as soon as the clutch pedal is pressed.
The start-stop system is quiet, convenient to operate, and fast – the engine has already resumed idle speed by the time the driver engages the gear. Over the combined cycle the potential saving is thus around 0.2 l/100 km – equivalent to 5 grams of CO2 per km. The system can be deactivated at any time at the push of a button.
The start-stop system has been available since June 2009 for the following models with manual gearbox: A3 1.4 TFSI®, A3 1.6 TDI® 77 kW, as well as A4 2.0 and A5 2.0 (in each case TDI®, TDI® quattro®, TFSI® and TFSI® quattro® versions).
