Here's some news! They have released Renegade pricing in the UK along with official specs. Here's one article I have found, but there are more.
One thing that I don't find very promising is the vast difference between the base model price and the TrailHawk price which is right around 11k pounds.
If the American Renegade TrailHawk starts a thousand less than the Cherokee TrailHawk, I'm not sure what I'll buy.
