Got the wife her dream car last year, a 2018 grand cherokee overland black with black interior, all the bells and whistles etc...anyway,v6 with 8 speed, pretty peppy by my standards. I’ve gotten it up to 100 with ease and in very short order, still pulling pretty good but I was satisfied with that. To the point: recently my wife admitted she had done something “ stupid” and only told me because not being a car person she thought she may have damaged something. She claims that she wanted to see how fast her baby would go, so while out on a nice long straight country road let it buck. How fast? She said it was doing 150 and still climbing. She only let off because it started to become unstable and there was a burning smell.is this possible??? No way will I attempt to test this out. Ive read other people have had theirs to 130, and of course the track hawk will do 180. I asked if she may have had the speedometer set to kilometers and her reply was no. So....?????
