A1 EquipmentEfficiency

The Audi A1 Consistently efficient
All of the engines employ direct fuel injection and turbocharging. This downsizing concept coupled with technologies from the Audi modular efficiency platform give them tremendous power with minimal fuel consumption.

Start-stop system

The start-stop system turns the engine off when the car is at rest, if the gear selector lever is in neutral and the driver’s foot has left the clutch pedal. Start-stop then turns the engine back on as soon as the clutch pedal is depressed — all the while functioning quietly, conveniently, and quickly. The start-stop system also harmonizes perfectly with the seven-speed S tronicS tronicFaster gearshifts, sportier driving: the S tronic combines the sporty characteristics of a manual gearbox with the advantages of an automatic.S tronic .

S tronic

module_03

The Audi dual-clutch transmission S tronic combines the convenience of a torque converter transmission with the dynamics and efficiency of a manual transmission. It changes gears within a few hundredths of a second without any perceptible interruption of pulling power, smoothly and very comfortably. Weighing only around 70 kilograms (154.32 lb), the seven-speed S tronic also helps to save weight. Its two clutches run dry – the elimination of the oil supply further increases the already high efficiency of the transmission. Power is supplied to the electrohydraulic actuator as needed.
