**NEW**4.8 V8 Pentastar based engine for next gen WK(2015-16)?
 
Looks like Chrysler is working on a NEW 4.7--4.8 V8 based on the Pentastar engines we have now. These will DEFINETELY be used on the Grand Cherokee for 2016 if everything comes to fruition. Expect much better fuel economy from the new V8 and more HP/TQ than the current 5.7 hemi. Looks like the next gen WK GRand Cherokee is gonna be epic!

Where are you getting the info? I would like to read a little more about some of the speculation.

Lol it never ends. Now people dying to order a 2014 are gonna see this and want to wait for a 2015. Best thing to do is take delivery of your Jeep and never visit JG.org haha

LOL....I have known for awhile there was gonna be a new V8. Chrysler has so many engines being developed right now...its ghard to keep up! Theres also a new 3.0 forced induction motor in development for SRT and Maserati, 3.2 Pentastar, 4.0 pentastar etc. with direct injections to multiair systems

5 liters is v8 territory for 87 PON, may look similar to a Pentastar but bet the intake and exhaust paths are completely different, flows in a 8 are not the same as a 6. Prolly DOHC for VVI and VVE & an alloy block. Might have same bore/stroke/bottom end as Pentastar for parts commonality & ease of same assembly line but would need an offset crank for even fire in a 60 degree block.

its either a mini-hemi or pentastar base 3.6+ 2 cylinders


also hearing rumors of a 3.3 twin turbo at 420 hp and a single turbo variant at 370 hp

So........ where did you get the info? Was it a dealer? Was it from the internet? I was hoping for a link if it was possible.

I have no desire to have a Pentastar based V8. It just doesn't have the low end grunt that an old school V6 or V8 has. Sure it may have better peak hp numbers, better fuel efficiency numbers, but that's at the expense of driveability.

GM's V6 now is a prime example. Never has 300hp felt so gutless and strained to move a vehicle.

Torquey power is where it's at, and I'm concerned that an engine such as this wouldn't have the low end grunt I like about the Hemi. I could have bought a lot of other vehicles, but I liked that the Hemi had that low end grunt I wanted. If I didn't care about that, there's a lot of V6s out there which could have worked just as well.

The 4.7L in 08+ ws a "mini Hemi" and it didn't work. Price difference wise, people will just buy the Hemi.

Lol.....how do u even know before anything is released? A higher HP modern engine that gets better fuel economy than the antiquated hemi is seriously what Chrysler needs to keep up with the competition.

I think Chrysler needs to set new directions, be the leader, not be trying to keep up with the competition. When trying to keep up, you are always behind :)

LOL...maybe this is forging ahead of the competition?
