I am taking my new c7 on it's first road trip. '14 coupe A6. going from central Florida to Southern FL. I will spend a couple hours on the turnpike and I cannot find in the manual if can I shift to ECO while driving. I always drive in sport.
I guess my second question is why ever leave sport???
You can select any driving mode whenever you want. If you're on the interstate and want to save a little gas to stretch your tank and cruise in eco, I don't see anything wrong with that.
FYI Do you have a stick or automatic? Do you have a Z06 or Stingray? I just drove to the Ron Fellows Driving school. I have a stick and followed an automatic. We tried to figure out why the automatic got much better gas mileage than my stick. Long story short the Stingray automatic will drop to run as a 4 cylinder in any mode but the stingray stick will only go to 4 cylinder in the ECO mode. You can make any mode change at any time

Thanks Dave
Your A6 will go into V4 mode ANY time the parameters are met, regardless of driving mode. The only way to disable this is to drive in M. The ECO mode only extends those parameters, and keeps the car in V4 unless heavy acceleration is needed.
You can shift to any mode while driving. As to why you would want to leave sport mode, the ride is softer and steering is easier in tour mode. Shift to Eco mode for a little better mpg. Experiment with each mode while you are driving and you will notice the difference. Enjoy your trip.
If one were to choose eco mode and compare it to sport mode in the same Z51 gearing over the same road using cruise control, how can eco produce the mpg improvement?
Does it go quicker into 4 cyl mode? Does cruise control acceleration and braking change? Does the exhaust really differ in cruise control? I can't find this in any thread so far. Which of the following variances would account for the claim?

Reason: typo
AFM being in Eco mode could also have something to do with it, but I've never understood whether that system does anything else other than open and close the valves before the mufflers. I suppose AFM may also have something to do w/ ECM programming, such that you're in 4 cylinder mode more often.

Only true if he has magnetic ride control...which is probably not like the case since he has a '14 and his avatar looks like he does not have the Z51 wheels...
Why leave sport mode? Why to use the other modes. They are useful. For example, Weather mode is good for rainy weather. Eco is good for highway cruising. People scuff at it but why not - you're not racing in cruise control on the highway and as soon as you step on the gas you get all 8 cylinders. Tour is a good overall mode. It's good when you're driving through the neighborhood and don't want to make a lot of noise.
I think leaving it in sport or track mode all the time kinda numbs your ears to the sound as you get used to it. I like it when I go into Sport mode and say "Oh yes... That sound".
