Hello all... While I love my 2018 Elantra Sport, I confess to not being that much of a technical car guy... But I'm curious... what exactly does "Sport" mode do? I know it changes the gearing somehow, but I think I read somewhere that it also changes the handling and steering characteristics. Can anyone shed some light on that? Also, how often does everyone use it? It certainly increases the fun factor and I find myself popping it into that mode quite often. What are your likes and dislikes? Finally, is there any way to make it the default mode so that it stays on? Thanks for any and all replies! Jim
