I went for a test drive in the 2011 Grand Cherokee 3.6, and I was not that impressed with the engine. So I did a little research and I do not think the 3.6 is the answer we have all been looking for. Sure it should get a little better mileage but the extra torque comes at a price, yet another 1400 and 800 rpm respectively. Really exactly how important is the horse power number being 290 at 6,400 rpm!!!
I for one have just sold my 09 2-Door JK and I am getting a 4-Door. Either a '10 or an '11 depending on if I can find what I want. I am sure I am going to add a Ripp Super charger and be done with it. I was toying with the idea of a Hemi but 20 large is just to much to spend. After my test drive the the Grand Cherokee, which btw is amazing inside, I just don't see the engine helping a JK enough.
Just my 2 cents. What are your thoughts?
