Sport mode all the time and ECO when in bumper to bumper traffic. It helps me keep from over accelerating.
I’ve tried sport mode on 2016 QX60 and I leave it off because I don’t have the control I would like at the low end (the over accelerating I think BobOB is talking about). The QX60 is pretty tame in normal mode which is great for most driving, maybe even a little sluggish to me so I tried sport. I found it a DRAMATIC change. It’s fun when your wife jumps on you growing like a tiger, bites your neck and starts tearing your clothes off. . .but most of the time that kind behavior is impractical. It was the same way with sport mode for me.
I would have been sold on it if it gave me a standard pedal response below 1000 RPM and then took off from there, but it assumed I want to evade the police and I could not feather the pedal for the control I wanted-and my foot is pretty sensitive. Full disclosure this is wifeys car, my daily is a Cayenne Turbo and I have a 911 for fun weekend driving and sport driving to me is more about controlled response through the range (whatever that is for the vehicle) and I don’t want to lock in fire breathing berserk mode on public roads.
I had fun with sport mode and was very impressed with the performance while tearing around-surprised the QX60 had that performance to be honest, but I don’t want to chirp the tires after every stop so I will save this for empty parking lots after a light snowfall.
I will keep playing with this, maybe it’s adaptive and will smooth out after a few minutes but these are my first impressions.
