I'm more interested to see what drive train they put in it. A new vehicle model is a great opportunity to introduce a new drivetrain line.
Supposed to be the same as the JL... the updated 3.6L V6 gas engine and the 3.0L turbodiesel. The gas will have the auto and manual transmissions, the diesel will only come with the auto (per reports). I'm not sure about the axles, rumored to either be the same as the JL (standard and heavy duty/Rubicon) or possibly only come with the Rubicon axles (a little wider than the standard). It will have more payload and around 6500lb tow rating, though... not sure if that's just because of a stronger frame, longer wheelbase or the possible Rubicon axle upgrade.
