I can't say I've noticed much difference between Normal and Eco. In fact normal seems to give me better mpg figures.
 
I've not seen much difference between eco and normal, except eco ACC doesn't accelerate up to speed as quickly.

Switch to Sport and it feels very different, not just power/throttle response time but something about the way the car handles. As my g/f put it, it feels a bit more "flighty".

If you select the INDIVIDUAL mode on the screen it gives you the option to mix the settings

Throttle response ( Sport or Normal )
Steering ( Sport or normal )
Air Con ( Normal or Eco )
 
+1 I can't see it being wholly practical or economical to have a separate 'map' for each driving mode. Surely limiting throttle response is the easiest thing. Don't the DSG cars have a 'kick down' function in ECO mode wherein you plant the throttle and you get the full fat acceleration?

Not just the DSG, I have the 184 6 speed and there is a kick down on the throttle in eco mode. I hadn't realised as I was overtaking on a long straight on a B road in economy and a car came into view. I was doing 4.5k in fourth when I pushed the pedal to the floor and the revs took off to the limiter. It caught me out as I wasn't expecting this to happen.

Try running on the cruise control at motorways speeds and brake at 70 mph to let the car drop to 50mph and then press the resume on the CC.

In eco mode the time to return to 70mph is far slower than normal mode.
