Re: 5.7 falling behind…

They could easily get more power out of the hemi. Go aluminum block, better cam, intake and exhaust. The aluminum block won't add any power but would shed some weight and keep the displacement. I'm not a fan of the smaller turbo motors like everyone is going to.

5.7 falling behind…

Aren't they making improvements to the 2016 Hemi?

The GC Hemi would be something to really bitch about, had they not put the 8 speed transmission in. It was a total dog before.

The EcoBoost is also detuned in the Explorer and Taurus vs the F150.

I'm pretty sure if you're choosing a particular 4WD SUV for its ability to beat other vehicles off the line, you're doing something wrong...

If you want a sports car, buy a sports car.

If you want a vehicle that can tow far more than its own weight and get through just about anything that will leave other vehicles stuck, then you buy a Jeep.

Having said that, I would prefer to see a more Apples to Apples comparison to those other vehicles using the 8 speed V6...

They can add 35 HP by changing the hood, and using the intakes off the 5.7 Hemi used in the trucks with variable plenums.

If people who bought these new, when sent their surveys would complain and suggest they do that, maybe they would listen. I listed that as an item they should jump on ASAP.

These minivans the OP listed do not have the capability the jeep has. I beleive on Allpar there was a discussion about this with a couple engineers who are on the list and share tidbits. Jeep does competive testing on a simulated off road course. One of the Engineers mentioned the Explorer was brought out on this course and within a half mile was stuck and 20% of the spot welds had popped. there is a reason why jeeps are heavier LOL

Re: 5.7 falling behind…

What a waste of a thread!

But i give my input. 0-60 boo hoo, they are .3 or .4 faster. 0-60 is from a dead stop. Now if you ask me, and that's only if you ask, anyone of those mall crawlers may give a hemi a runs for its money only if they gun it from a dead stop and go. Surely those 6 bangers won't out run a hemi while trying to switch lanes, prevent someone from cutting you off...etc, Its just not possible since none of those are pushing enough tq to play with a hemi.

On another note, car and driver and their numbers i would assume they got that off a hemi with eco on and not on sport mode. Just saying...

Let me go waste my time reading another topic that's been discussed before.

Except GC, all the above are V6s (all turbos except Honda), AWD.
(The Mercedes’ horsepower figure is questionable given those specs, IMO.)

I don’t wish for the 5.7 to go away. I’m happy I can still buy an affordable V8 SUV. I just wish they could find a way to get it to breathe better in the GC.
None of the others can tow over 5000lbs.

The V6 GC (2014+) can tow 6200lbs.
The V8 and diesel GC can tow 7000lbs.

Take any of the others off road and your are going to be breaking plastic off the front end.

What's the comparison?

While I'm not a ford fan, there is no way 20% of the spot welds popped. I'm betting none of them popped. The Jeep is a much better off road vehicle no doubt but it's a trade off for handling or ride on the roads.
I think the Jeep suffers from heavy use of torque management that hurts it's stop light to stop light performance, once it hits 3000rpm it comes alive.

A turbo on the 5.7 would help, as would simply increasing the displacement.
This would possibly require a bit more beef in the 4WD components to keep the genuine off-road capability that few of the mentioned "faster" competitors have.
The transmission could easily handle more power.

Whether the marketing wonks and senior management want to go that route is unknown but dubious given the current climate climate.

I wouldn't mind an Overland with the full off road goodies and an SRT 6.2 or larger.....
but I'll give up blowing off Hondas at streetlights to be able to go pretty much where I damn please--road or not.

Go say that to some of the JTE people on Allpar and they will rip your head off.

You dont know the things they abuse and test on(some) Jeeps that other OEM's could car less about.

Exactly. A person doesn't buy a 2-1/2+ ton SUV that can tow 7,000 pounds for "0-60 times". If you want that buy a HEMI in a high performance car instead. For the price of a fully decked out Summit or Overland you could damn near have a Hellcat. That would blow those turbocharged tin boxes right off the road. Apples and oranges.

Re: 5.7 falling behind…

This discussion was probably dead before now but, just for fun...

There is an easy fix for your 0-60 time woos, a 75-100 shot of nitrous would definitely get those times down if you were so inclined. Also, assuming you don't overdo it and don't hit the "Lightspeed" button at every traffic light, it shouldn't do too much harm to the motor and drivetrain components if set up correctly.
