the 3.6L Pentastar definitely has more powerful and torque than the 3.7, 3.8 and 4.0 HO. - It has 4.7L HP - but it's shy of that 4.7L torque - but it is actually pretty close and those who have driven wranglers and cherokee's/grand cherokee's with the 3.7, 3.8 or 4.0 - will feel the difference when the step on the gas. Wranglers folks will love it...
