I have an 08 JKU with the 5.7l Hemi and agree that it’s not ‘fast’, it’s just faster than what it was. That said with how heavy the JKU is the 5.7 feels and drives like it should have been a factory option. Not fast, not slow, and gobs of low end torque that makes hills and off roading a breeze. Based on the rumored hp/tq numbers I would guess that the upcoming diesel might behave in a similar manner, and with a good tune on it I think the demand for a hemi could be a lot lowerAs someone with a 5.7 Hemi TJ, it's no high performance racer. I get out run by most soccer mom ford explores and the likes. What it has is massive torque over the 6 cyl and this was from the inline 6. If you drive it without footing it, it gives back 1 to 1.5 miles to gal better then the 4.0 it replaced. It should be a option from the factory. with MDS I'm sure it would bring better mpg. Work the throttle and yes it will drink fuel fast.
no you wouldnt, on allpar there are mopar engineers, hemi is cheaper to make than the old 3.6 and much cheaper than the new version with cooled egr, hp70 they already make, beefier transfer cases are already designed etc, so would be parts bin engineering. only thing preventing it would be fitment, cooling and fuel economy which was probably what sank it, you can thank Obama for torpedoing anything like this. going forward you will have complex high maintenance cars/suvs to meet fuel economy stds. look at all the damn hoses and lines on these things, all which will need to be replaced. coolant modules run to the transmission to heat and cool the fluid, on the rams they are doing same to the diffs, all these things will either rot out or the rubber sections will have to be replaced at some point, big moneyAnd now you have a 85000 wrangler
I'd trade my 2018 JL in for a Hemi JL in a heartbeat. That being said after 5K miles the V6 moves off the line pretty good. Anyway I like the sound of a Hemi(had a 6.4 challenger). You have my vote. Have a great day.I’ve been reading a lot of posts and articles about how excited some people are about the 2.0 turbo, and the upcoming Diesel engine that is going to be offered. Just curious if I’m the only one kinda disappointed that they do not offer at least the 5.7 ltr Hemi engine in Wranglers. They offer them in the Grand Cherokee. I think the 5.7 ltr Hemi would be perfect for the Jeeps especially with modifications when you start running 35s or 37s. Offroad man you’ve got that Hemi power on tap. I would think fuel efficiency would be no different than the Grand Cherokee. The rubicon would definitely be able to handle the power. I’ve seen through YouTube a company in Colorado that will do the 5.7 or 6.4 ltr conversion but it’s not cheap. Anyway, I vote for Jeep to add at least a 5.7 ltr Hemi option to the line up.
