Is there any advantage to using the Sport Mode Selector? If so when should it be used? What exactly does it do?
Many Thanks JB

Well, your Computer selects the speeds and RPMs it needs to make your car either economical or just plain Fast, based on you desired setting.

If you are going to pass a lot of cars on two lane going 60 MPH and need to get up to 80 real quick, you would want the sport setting..

IF you are just interest in puttering around town with the rest of the crowd, Econ mode is just fine.

In Sport mode, the computer will want to get you up into your max HP range before shifting, whereas for econ mode, the computer will shift up early at a lower power output and RPM.  I'm sure I over simplified this, but that's kind a how it works.
