5.7 falling behind…

The following are Car and Driver test results, including weight.
0-60 5.1, 2016 Merc GLE 450, 362hp, 5126lbs, 18mpg (bigger than GC)
0-60 5.6, 2015 Ford Edge Sport, 315hp, 4437lbs, 16mpg (same size as GC)
0-60 6.0, 2016 Ford Explorer Sport, 365hp, 4939lbs, 18mpg (bigger than GC)
0-60 6.1, 2016 Honda Pilot, 280hp, 4302lbs, 18mpg (bigger than GC)
0-60 6.5, 2014 Grand Cherokee 5.7, 360hp, 5324lbs, 16mpg

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.

Re: 5.7 falling behind…

The current climate here is one of angst and apprehension towards any forced induction. So I am not sure what you are trying to tell us by "5.7 falling behind".

Are you suggesting that it's technology and design is getting too long in the tooth ? We learned in this thread that forced induction and dual overhead cams with 4 valves per cylinder have been around almost 100 years.

Re: 5.7 falling behind…

I'm a little confused with the "bigger than or same size as the GC" statements. Every one of those vehicles are lighter than the GC, a couple by around a half ton. Nothing stated about the final drive gear ratios either. Doesn't seem like much of a comparison to me.

Yeah, that..

The "bigger" math seems backwards..

F1anatic: not suggesting that necessarily; as I said, I like and want the V8, and I'll add, in NA form. I just wish Chrysler could get a little more out of it in the GC. The bar is being raised, but the 5.7 is not keeping up. That's my point.

MD: Just pointing out that the bigger vehicles are faster partly because they are lighter. Now obviously, superior off-road capability adds weight. So I guess I'm suggesting that other vehicles are more efficient if you don't need the off-road capability and that I believe the 5.7 should be making up for this difference, but it's not.

Re: 5.7 falling behind…

Its a tough comparison because when you look at the numbers like that then yes it appears the Grand Cherokee falls behind a bit. However, the WK2 has been out since 2011 model years, which means they have been on the streets since sometime in 2010, and were designed well before that. So technically we are talking about an aging design. Chrysler could have put as much power into the Hemi as they wanted.

The 2016 Honda Pilot is brand spanking new. I would actually be pretty surprised had it not had as good or better numbers than the Grand Cherokee. The Ford Edge weighs the same as some cars, so thats not even a fair comparison. As far as the others I don't know details about those, but what about towing or offroad capabilities? There is much more to it than 0-60 times. If that was the main test then we should be discussing the SRT which blows those all away....and wouldn't be compared to them anyway.
And for what its worth when I get on my 2014 Summit V8 it feels like it pulls pretty hard. I enjoy it!

Right, you explained in detail why the 5.7 is falling behind, thanks.
I do believe they could get more HP out of the 5.7; it makes much more in RAM pickups, but others here said intake/exhaust restrictions in the smaller GC engine bay are the difference. However, I suspect Chrysler wants to keep a good performance distance between the 5.7 and SRT.

If (0-60) was the main test then we should be discussing the SRT which blows those all away....and wouldn't be compared to them anyway.

You probably hit the root of my discontent: I really want an SRT. But I just don't want to pay that much for a car (any car). So I wish I could get more out of the 5.7.

Your comments about these vehicles being "Bigger" then the GC are misleading at best, and flat out wrong at worse.

NONE of those vehicles are heavier then the GC and THAT is what matters regarding engine performance and 0-60 times!

huh? they are bigger: length and width (mostly length), those are facts, what don't you believe?
And despite being smaller (or close), the GC is heavier, again, just the facts. Weight hurts performance, I understand. I explained above.

Yes, true. Its just that every time I see another road test of a V6 SUV/crossover that's quicker than the V8 hemi, it bugs me, and is yet more evidence that the 5.7 is falling behind. I think Jeep should pump it up a bit.

Re: 5.7 falling behind…

I'd take a Pilot/Edge/Explorer if they could tow 7,200. The Hemi's grunt up a hill with my trailer behind me outweighs the 0-60 times every day for me. I don't find myself trying to beat other cars off the line too often :-)
