What is the green battery section on the right hand side of the consumption bar?

The fuel consumption bar is pretty obvious for the most part... running average for the trip and where you are right now.

The bit I don't get is the green battery section at the extreme right hand side. What is that supposed to signify?

Re-couperation?

My dealer referred to it as KERS - the kinetic energy recovery system as per Formula 1!!!

Basically as part of the efficiency program within the car, the alternator generates more electric to charge the battery when you are on over-run, adding to engine braking (a little I guess) and generates less electric when you have power on, therefore saving petrol if you follow.

The green bar indicates when the extra battery charge is happening

In the words of greatness that is Tesco, "Every little helps"!

OK thanks!
Pretty much what I expected - eco-auto-regen stuff... but can I find it in the A6 user manual? NOPE.
Maybe I missed it but I have trawled around the ToC and Index in both the Owners Manual and MMI Nav Manual and not even found a graphic that shows that specific display let alone explain it :)

From the Audi website:

Saving while you brake.


Recuperation, from the Latin, means recovery, reclamation. The principle is quite straightforward: when a conventional vehicle is braked, the brake converts the kinetic energy into thermal energy, which cannot be used for any other purpose. With a recuperation system, the kinetic energy is converted into useful electrical energy. While the vehicle is coasting or braking, the alternator voltage is raised above the level of the basic electrical system. During these phases the alternator can convert the vehicle’s kinetic energy into electrical energy, which is stored temporarily in the vehicle battery. When the vehicle subsequently accelerates or is driven at constant speeds, this energy is used to relieve the load on the alternator and, depending on the driving cycle, a fuel saving of up to 3% can be achieved.

Which means that the battery gets charged quicker which then allowed that battery to to support the air con, etc during the 'stop' status in stop/start?
