I would also pay the higher fuel costs, but would want a larger gas tank to keep the range the same at least.I can't answer that, but there have been posts about how hard a turbo 4 has to work to maintain speed into a headwind. It's constantly in boost mode which kills mileage. A V8 wouldn't have to work as hard as the turbo 4 and likely not as hard as the V6. But I am no expert, just extrapolating. Mileage has to be worse than the V6, especially if you put your foot into it a lot, something I'd be hard pressed not to do but I can't imagine it would be much worse.
I would gladly pay higher fuel costs and higher vehicle cost to have a 5.7L Hemi.
IMO based on looking at RAM, Charger, GC numbers etc, it’d be right next to the Pentastar in EPA testing, likely -1 or so on each metric; however in the real world with cylinder de-activation and the V8 likely to do 75MPH/120KPH (BC speed of course not advocating speeding ) without breaking a sweat, I think you’d find the Hemi close the gap with the Pentastar and possibly cross over.Hypothetically speaking, what would a Hemi JL get for MPG?
For the price difference of the Hemi vs EcoDiesel on the RAM or GC, you could add a 10-20 USGal (40-75L) extended fuel tank to add 50-100% more fuel and provide greater range than even the new efficient EcoDiesel.I would also pay the higher fuel costs, but would want a larger gas tank to keep the range the same at least.
The Hemingway Grand Cherokee only gets 14 city/20 hwy. So probably minus 1 city and minus 3 hwy 13/17.Hypothetically speaking, what would a Hemi JL get for MPG?
Good that you mentioned that the Hemi deactivates 4 cylinders which we don't even notice on the highway the 8 speed transmission also helps keep things running smoothly. The Hemi in the Ram does indeed do 120 KPH without breaking a sweat and if you don't set the cruise to a legal speed it is easy to start creeping past tIMO based on looking at RAM, Charger, GC numbers etc, it’d be right next to the Pentastar in EPA testing, likely -1 or so on each metric; however in the real world with cylinder de-activation and the V8 likely to do 75MPH/120KPH (BC speed of course not advocating speeding ) without breaking a sweat, I think you’d find the Hemi close the gap with the Pentastar and possibly cross over.
However the diesel again would likely be the far and away EPA winner by a few MPG, and that’s the current ED, I don’t know what they are doing to Gen2/Rev3 to get the 30MPG figure mentioned, but as the Ram 1500 2WD/4WD gets 27 hwy, there must be some major fuel economy measures coming in the next gen EcoDiesel as the Current RAM 1500 Pentastar matches the JLU’s hwy mileage, and it’s EcoDiesel brother is 27MPG, so it’ll be interesting to see where they find that 3MPG.
And yet again, this comment needs correcting, that was before they stretched the JL to accomodate the 8-speed and diesel. In that same comment you like to quote he was even more dismissive of the Ecodiesel ever fitting in the Wrangler as it needed more space, so that statement no longer applies.From a former chief engineer: There will be no Hemi for the Wrangler because they can't shoe-horn it into the engine bay with the 8-speed auto.
Again, there’s no need for 5 different engine on the GC or Charger/Challenge, yet they are there.Also, there's no need. The EcoDiesel makes more torque than the Hemi and the Pentastar is capable of 300+ horsepower which puts them firmly within target for the vehicle.
Again, this same logic applies to the diesel. There has never been an N.Am. diesel Wrangler... so there won’t be...There hasn't been a factory V8 Wrangler ever. And there won't be. If you want a factory V8 Jeep, start shopping CJs.
a 285 hp v6 is more powerful than several V8s I have owned in the past.So the JL will eventually have 4 powertrain options, and none of them are a V8. And this from the same company that has a penchant for jamming 700 horsepower engines in everything from sedans to SUVs.
Actually, the initial assumption was that Jeep would stick with the 2.8L that it had been using already, and GM is now having success with it also, and therefore fitment issues with the diesel were not a hot topic. Even so, a 3.0L V6 is much easier to fit than a 5.7L V8, so this argument still stands. The Hemi won't work from a packaging standpoint.And yet again, this comment needs correcting, that was before they stretched the JL to accomodate the 8-speed and diesel.

As much as the Hemi isn’t coming, any argument you have for why it doesn’t work on the Wrangler platform applies to the diesel as well, the only thing in the diesel’s favour is the externality of CAFE, and once again if they can make a Dodge Demon and all the Cats/Hawks and SRTs work, an SE Hemi is not a challenge either.
