JKU 2013 6 speed, 3.73 ratio owner here. I don't think the new JL will be much faster.
A few factors that don't help: it's a brick, it's heavy, the engine wakes up over 3500 rpm and it also depends on your added options that also will add weight. You got to go through the gear and push it. And...
Just got this in my email today and those 2 JL in the video are close to the rendering we have seen on this page?
Is it me who's seeing wrong or what???
