This was my first chance to drive the Hyundai in the mountains, and I think it did well.  While hardly a sports car of course, it managed smoothly.  I hit a few turns faster than I thought prudent and it handled them without screeching tires.  Somehat unexpectedly, it hit 39 mpg in mostly mountain driving.  It usually is around 32-33 on freeways at 75-80.  My wife wanted me to try for 40.
Anyway, fortunately, it is an upgrade from the GTI for us olden folks.
