Modular efficiency platform
The innovative technologies that constitute the modular efficiency platform play an important
part in improving fuel efficiency and cutting CO₂ emissions in all Audi brand vehicles. The steadily
growing range encompasses various efficiency modules that have already been adopted as stan-
dard features in numerous Audi models. The technologies are continually being refined – for
instance the start-stop system became available for automatic as well as manual models in
fiscal 2010.

Predictive gearshift strategy
Advances in transmission technology, under the umbrella of the modular efficiency platform,
likewise improve efficiency. Transmission functions have already previously been improved by
incorporating information from other sensors and control units – for instance, the driver can
now see on a gear-change indicator how best to time gearshifts from an efficiency viewpoint.
A new feature is that route data from the navigation system is now evaluated in order to optimize
changes of gear. This supplementary information for example avoids unnecessary upshifts just
before a curve, promoting an altogether more economical driving style. The “predictive gearshift
strategy” was adopted for the first time in 2010 in the 8-speed tiptronic in the new Audi A8.
