Re: Question about Sport Mode.
This question has been asked several times here, but no one has really given a confirmed answer. Some people say it should improve fuel economy, and others say it will be slightly less in sport mode.
If there is a difference its minimal, but I personally like driving the car more in sport mode, but the delayed shift into 5th annoys me especially since that speed range between 45 and 50 is a very common speed that people cruise at. So unless you get it above 48mph the rpm's just hang until you either speed up a little, or shift it into 5th manually.
The perfect "mode" in my opinion if we were able to customize one would be sport mode charecteristics and ride height, with auto shift points and full ESC (so the stupid light doesnt stay on).
I think the best way to find out would be do a full tank of driving strictly in sport, then do another tank in nothing but auto. If your daily driving is pretty consistant such as your work commute, then maybe this method would show some somewhat accurate results.
