Same octane recommendation as the equivalent hemi and close to 10% better economy with no e-torque. Also lighter weight and will have a way wider torque curve which means more power where you use it, especially with the shorter standard axle ratio. We don't know the real world mileage of this motor yet so I don't know where you are getting that info from. The hemi is a great motor but is down on power compared to the competition now, if we can get a lighter, more powerful, more efficient option then count me in! Its not like a hemi is as simple as an old small block, they still have VVT, DOD etc. as well as e-torque on the Wagoneer and lots of the rams.Mid/high octane only, same MPG as the current offering in the real world, and more sophisticated (complicated) design?
I think I'll pass....

Why does the HO get a 400# lower tow rating?
Hurricane SO 10.4:1EPA rated it 14/20 and 17 on the combined cycle. I'm pretty sure the 5.7 Hemi in the Rams is rated 19 with eTorque, right? At $5.00 gallon those 2 MPG are substantial.
Let's also remember that a smaller engine has to have more compression to produce the same power as larger engines, so by their very design they won't have the longevity of a larger engine.
Added weight?
Yep - lower compression to optimize performance with forced induction.Hurricane SO 10.4:1
Hurricane HO 9.5:1
Hemi 2009-up 10.5:1
I think because of the turbos lower compression actually produces more power than the Hemi does and it has higher compression.

The HO tow rating is probably lower than the standard because it is only available on the Grand Wagoneer. The Grand is likely heavier and tuned for comfortable ride rather than max towing. Both of the new hurricane options are 100LBS or more lighter than a comparable Hemi.I wondered if it was added weight, but could it really weigh that much more than the hemi?

Good question. The engine is significantly lighter than the Hemi's. So why would they drop tow ratings? Maybe they reduced braking or a frame/suspension component?Why does the HO get a 400# lower tow rating?
