Just had the car for a week. 160 miles so far.
Normal mode well is to normal.
Sport+ I use this 99% of the time. Makes the car a real hoot to drive.
Track mode. I have not tried this yet.
Drag strip mode. Used this one time at about half throttle. Big chirp of the tires from first to second gear and also from second to third. Will have to try this mode at full throttle soon.
Very pleased with the 10 speed auto trans.

 

Drag Strip mode must be new to the '18. Don't have that on my '17. I drive 99% of the time in Track Mode. Makes it just a tad snappier than Sport.

But I do miss the shifting style of my '06 after I did the Brenspeed tune. Shifting in any stock mode on the '17 just feels sluggish. The tune made it get up and go right off the bat and would chirp the tires all the way through 4th if you really wanted it to. Not even track mode will do that in my '17.

 

Yes drag strip mode is new for 2018 with the new 10 speed trans.
