Good question: it would be nice to see some numbers either in consumption or in power. However, I beleive it might not even be measurable?
However, I am really curious to see if it does include noticable changes.
"With new equipment features and optimisation in safety and efficiency, product quality offered by the models BMW M5 and BMW M5 Touring, the BMW M6 Coupe and the BMW M6 Convertible has increased even further in the model year 2009. In future, the high-performance sports cars powered by the 373 kW/507 bhp V10 engine will also feature brake energy regeneration and an air conditioning compressor which can be uncoupled - both features having been developed within the framework of BMW EfficientDynamics. Moreover, the new smooth-running bearing for the rear axle transmission is characterised by an optimised friction coefficient and its efficiency-enhancing construction. "
German:
Mit neuen Ausstattungsdetails sowie Optimierungen in den Bereichen Sicherheit und Effizienz wird die Produktsubstanz der Modelle BMW M5 und BMW M5 Touring sowie BMW M6 Coupé und BMW M6 Cabrio im Modelljahr 2009 nochmals gesteigert. Serienmäßig verfügen künftig auch die vom 373 kW/507 PS starken V10-Motor angetriebenen Hochleistungssportwagen über die Bremsenergie-Rückgewinnung und einen abkoppelbaren Klimakompressor - beides Merkmale, die im Rahmen von BMW EfficientDynamics entwickelt wurden. Darüber hinaus zeichnet sich das neue Leichtlauflager für das Hinterachsgetriebe durch seine reibwertoptimierte und damit ebenfalls effizienzfördernde Bauweise aus.
