Audi A5 Sportback Saving You Fuel

Start Stop
Why run the engine when you're standing still?

If you're stuck in traffic, what's the point of wasting fuel by letting the engine idle needlessly? Once up to operating temperature, Audi's start-stop technology cuts the engine when the car is standing still and in neutral. The engine immediately starts again as soon as you depress the clutch. The whole process is barely noticeable but it can be disabled at the touch of a button if required.

Recuperation

When you're coasting or braking, the car's alternator generates electricity. Recuperation allows it to be stored so when you're accelerating or driving at a constant speed, the stored electricity is used to drive the alternator. Recuperation reduces fuel consumption by up to 3% and therefore lowers CO2 emissions.

S tronic
Smooth gear changes, lower fuel consumption

The revolutionary S tronic transmission combines the responsiveness of a manual gearbox with the convenience of an automatic. Thanks to innovative dual-clutch technology, S tronic can make a gear change in just 0.2 of a second, with no interruption to the power flow, allowing you to benefit as fully as possible from the engine's output at all times, resulting in better fuel efficiency and lower CO2 emissions.

Driver's Information System
Driver's Information System with efficiency program

Individual driving styles play a significant part in determining fuel efficiency. The Driver's Information System with efficiency program, standard on 2.0 litre manual cars, helps by providing valuable tips and information to enable the most efficient driving style at all times.

Gearshift indicator - available on manual cars
Selecting the right gear at the right time is key to reducing fuel consumption. The Driver's Information System has a gearshift indicator that tells you when to change gear and which gear to change to. By following the system's recommendations, you'll drive more efficiently.

Comfort features cost fuel
Comfort features such as air conditioning and seat heating increase fuel consumption. The efficiency program helps you monitor this by telling you which systems in the car require additional energy and how high their share of fuel consumption is.

Helpful tips
Because the efficiency program continuously monitors fuel consumption and calculates how to optimise fuel efficiency, it is always on hand to provide helpful tips. For example, the program will advise you to close an open window while the air conditioning is switched on.

Aerodynamics
Sleek design for greater efficiency

Aerodynamic performance is critical for reducing fuel consumption and raising efficiency. Audi prototypes spend over 1,000 hours in a wind tunnel with improvements being made so drag can be reduced. Less air resistance also means improved handling, lower CO2 emissions and even improved safety. Improvements such as door mirrors which are aerodynamically shaped so rain is directed away from the side windows for better all-round visibility is another notable product of this extensive development process.

The Audi A5 Sportback has a drag co-efficient of just 0.29
