I didnt buy this truck to be the fastest car on the planet.....there is always someone faster BUT i ran it yesterday. Below freezing temperature, winters on, track mode with full traction off. dumped it, a bit of wheelspin and off she went. 0-60 in 4.4 seconds and quarter mile in 12.8 at 105. Dont know any wk1 that did that right off the showroom floor with 2500 miles. I still love the wk1 and indeed had two of them but this is the fastest Jeep I have had to date.
