I traded a 2016 Challenger Hellcat in for my 2018 TrackHawk. I had my Challenger to the 160-180 mph range many times. I have been very impressed with the TrackHawk. Living in a super cold snowy climate is not the most ideal for rear wheel drive hot rods most of the year. So today it was about 20 degrees F outside with 30-40 mph winds and I found myself full throttle. Didn't take long to hit 170 Mph. Other than the strong crosswind it was surprisingly smooth. She had quite a bit more left but that was enough for now until maybe a better day without so much wind. 170 Mph in a Grand Cherokee!! Damn if you would have told me that a few years ago I would have thought you were crazy.
