I notice with Econo Mode that acceleration is not as good as when it is turned off. Seems like it wants you to drive like a granny!
From the Sonata owners manual:
The ECO indicator light helps that you to
drive economically.
It is displayed if you drive fuel efficiently
to help you improve fuel efficiency.
• The ECO indicator (green) will turn on
when you are driving fuel efficiently in
the ECO ON mode.
If you don't want the indicator displayed,
you can turn the ECO ON
mode to OFF mode by pressing the
TRIP button.
As per ECO ON/OFF Mode operation,
refer to the previous page. (if equipped)
• The fuel-efficiency can be changed by
the driver's driving habits and road
conditions.
• The ECO indicator does not funtion in
P (Park), and N (Neutral), R (Reverse).
• When the instant fuel consumption
mode is displayed on the LCD screen,
the ECO indicator turns off (if
equipped).
Unquote.
So from what I read it is strictly a Off or On of the indicator and has no bearing on performance.
