Since the term Audi ultra is used to describe the lightweight engineering throughout the vehicle, it not only includes the body and its materials, it also takes all other components and systems into consideration. The principle is straightforward: the lighter the body, the better the weight/power ratio and thus the vehicle performance and efficiency.
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.
