Driver Select Modes

[carbuff2012]

The literature regarding Audi Drive Select for my 2013 A6 lists three modes:
Comfort
Auto
Dynamic

Although the terms are seemingly self-explanatory, I wish to learn about them in greater detail. Is there a source that I can access to further educate myself about these features?

I specifically want to learn the proper settings to achieve:
1. Optimum fuel economy.
2. Most driver handling ability.
3. What the Auto mode actually does.

Well if you want the best fuel ratios activate the efficiency mode with vag com and that will be the most efficient way to save on mpg's

Handling is dynamic mode for suspension and steering

Auto is comfort till the throttle response or steering angle warrants switching to dynamic
