New Jeep reviews?

[Spinalguy]

I dont know about the rating, but the pentastar is planned to be used in the next 2012 JK.

Linky to evidence.

i think they have more than one Penstar, just like the Challenger has different hp ratings on the same engines they use.
The Grand Cherokee is the only one that will get the 305hp version.
i read it somewhere like car and driver or some such publication. Actually, looking at your links, it mentions 283-305.
