I bought a Niro in September and still hardly know how to drive it. Put the shift lever in Sport position today and noticed no real change in how it drives. What's it there for? I was hoping for some engine compression braking coming down a steep hill with a turn at the bottom. Totaled a nice little Porsche there years ago spinning out on a slippery road. Big drop off on the sides of the hill. Had a boat on a trailer going down that hill (also years ago) and ball came loose. Safety chains broke. Boat and trailer hit a tree six feet off the ground. Got to admit my driving skills could stand a little work.
