Vorsprung durch Technik is the claim to which the Audi brand is committed. Not only where sportiness is concerned, but in terms of future-oriented mobility as well. Audi consistently implements various efficiency measures in an overall concept. As a developer of numerous innovations, Audi has had a long-lasting effect on the automotive industry.
Start-stop systemThe 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 (on manual transmissions) or releases the foot brake (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 ) for moving off.
RecuperationIncreasing the generator voltage converts kinetic energy into usable electrical energy when the vehicle is coasting or braking. This brake energy recovery is used to assist the generator during subsequent acceleration, saving up to 3 % fuel.
Audi drive select efficiency modeIn this mode, the vehicle is adjusted particularly efficiently and the driver is actively supported with a driving style that can reduce fuel consumption. One example: the modified shift program with S tronic with a conscious movement of gearshift point to lower engine speed ranges. Here, the freewheeling mode of the S tronic is also activated, which means the vehicle clutch is automatically released when the driver takes his foot off the accelerator pedal, thus saving fuel. In efficiency mode, the electromechanical power steering system, cruise control and adaptive cruise controladaptive cruise controlRelaxed and comfortable on long journeys: adaptive cruise control can even be used on busy roads and in dense lines of traffic.adaptive cruise control contribute to further reducing driving resistance. Equally, the air conditioning is adapted to requirements and switched to a working mode with improved energy consumption.

Onboard computer with efficiency programThe onboard computer is equipped with an efficiency program to reduce fuel consumption. The integrated efficiency program assists you with consumption data overviews, a display of additional consumers and fuel-saving tips for more economic driving.
S tronic®The S tronic transmission combines the low fuel consumption of a manual transmission with the benefits of an automatic. The control ensures fast and consumption-reducing gear shifting in automatic mode. The very large transmission-ratio spread of the S tronic allows the last gears to be used at very low engine speeds.
Audi ultraAudi ultra, the pioneering lightweight technology from Audi, is already being employed in the Audi A3 Sportback.
The steel shell design of the Audi A3 Sportback combines low weight with high rigidity. Which type of material is used in which place on the vehicle is determined by the desired characteristics. The resulting material mix of hot- and cold-formed metal panels and profiles in the vehicle body create an ultra-modern lightweight structure. But not only ultra high-strength steels are employed, light aluminium is also used to reduce the weight of attachment parts such as the bonnet and wings. The aluminium components on the front axle and the aluminium alloy wheels not only reduce the overall weight but also the unsprung masses, which in turn leads to a further increase in agility and driving comfort.
Modern TDITDISynonymous with muscular torque delivery and outstanding efficiency: TDI. Today, TDI engines are sporty, smooth and economical.TDI and TFSITFSIAudi was the first manufacturer in the world to combine petrol direct injection with turbocharging in large-scale car productionTFSI engines in the Audi A3 Sportback also produce more power with a smaller engine size, making them lighter than the corresponding engines used in earlier model series.
Each lightweight component has an effect on other components, allowing their dimensions to be reduced as well. In the Audi A3 Sportback the lightweight body and lighter engines lead to secondary effects throughout the vehicle. The weight of many parts of the exhaust system, suspension and interior has been able to be reduced. This complete package of measures for the new A3 Sportback saved up to 90 kg compared with the predecessor model.
