I think I have to learn to use sport mode. Our previous car (well, we still have it) was a Prius V and I never had trouble getting pep when I need it (passing, getting into a freeway, etc). But we've had our Kia Niro for a little over a month and have driven it from central Texas to Maine and back. I noticed a long delay in its revving up or whatever it needs to do when passing etc. (seconds, seems like hours). I'm saying come on car!, or some such... I presume that if I knew how to kick it into sport mode I would not have this frustrating delay?
