Re: Anyone else think the hemi is underpowered?

I wish TransGo would come out with a shift kit for the Hemi GC. I'd get it in a heartbeat, not that I am complaining about my Hemi. I just like quick.

How will it "easily" outrun the MDX when the MDX posts quicker times? The MDX runs a slightly better 0-60 time and is around the same in the qtr mile as the Hemi.

What compsison review was you looking at. Let's have the facts. Big difference between strip and street and trail. My sister in laws mdx gets stuck on wet grass!! Are you buying a suv for strip bragging rights or to get you from place to place on poor road conditions.

Re: Anyone else think the hemi is underpowered?

I own a 2011 range Rover sport and a 2011 hemi overland, when I first drove from the dealership to my house I was so scared that I paid 41k for a v6 and I hurry up to open the hood as soon as I got to my garage just to make sure this was a V8.

The RR sport is way faster and smother, I think the hole problem with the Cherokee is not so much the power, I think the problem is the shift points and gear ratios, come on who uses a 5 speed gear box this days.

A little more power and exhaust note wouldn't hurt either.

I never said the mdx out performs the wk2 off pavement or in nasty cond...I was simply stating that it is just as quick if not quicker then the hemi wk2...geez. The last I looked, this thread was discussing engine performance and how sluggish the Hemi feels compared to other vehicles.

Re: Anyone else think the hemi is underpowered?

Seems a lot of people on here accidentally bought a SUV instead of a sports car. They do park the chargers close to the Grand cherokees. Be more careful at the dealership.

Re: Anyone else think the hemi is underpowered?

I was going to say the same thing. If you wanted a fast GC then you should have went with the SRT8.

Re: Anyone else think the hemi is underpowered?

I've got a '12 with the hemi and a 6spd and it seems plenty fast to me for an SUV. I didn't buy a sports car, but I do know that my GC will get out of the way with a quickness. Sometimes I too think I'm going slow, because it rides so smooth and quite, but when I look at the speedo it's reading 65-70, not the 45-50 it feels like. I will also say it does get 100 quicker then anyother SUV I've driven. I love it and I'm extremely happy with it.

Re: Anyone else think the hemi is underpowered?

There is nothing wrong with the V8 engine in the 2011/2012 WK2.

But there is something wrong with the gearing and shift points. The factory tune is far too conservative.

A good tune would do wonders for the responsiveness of this beast.

Why does everyone say that the hemi has a 5spd tranny? Whe i build mine the only option is the 6spd.

My previous vehicle had the same engine as the MDX in a FAR lighter vehicle. It felt quicker than the Jeep by a lot, but in reality it isn't. And that engine you had to rev the bejeezus out of to get it to move the thing up a hill. THe Jeep's V8 doesn't break a sweat.

The new 5.0L DI V8 in the RR Sport is a hugely awesome engine. It's rather unfair to compare a 400+ hp, very advanced engine like that to the Hemi. If you compare it to their previous V8, the Hemi wipes the floor with it. In terms of performance, the Jeep is a decent bit faster than the previous RR Sport and about equal to the previous RR Sport Supercharged.

That said, Chrysler builds in a huge amount of torque management to the programming of the PCM. Almost all domestics do nowdays. That's why you can look at the GL450 and the Durango R/T and the GL450 is faster in all measureables than the R/T despite being heavier with less power. It's not the number of gears, it's the fact that they're cutting out a lot of power in low gears, before gear changes, and purposefully slowing the gear changes down - all things that are ostensibly done to reduce warranty costs.

I expect that the new transmissions will make the issue worse if anything, it's unlikely they will reverse course on the TM. The transmissions in the Jeep now are also found in the Ram pickups, so they're capable of holding up to abuse. With an outside transmission that will be their first use of it, I don't see them going with any less TM than before, if anything it will increase to reduce chances of having to eat warranty costs. Thus with more gear you'll have more gear changes, and more times that TM will rear its ugly head.

And the 5 speed tranny IS the 6 speed tranny. There is no difference, it's just a marketing change. The "5 speed" has technically always been a 6 speed, it has a secondary kickdown gear it doesn't usually run through, so when you're in 5th you're really in 6th. The "6 speed" just has a name change and a software change to allow you to manually access it via autostick or paddles, but AFAIK it still won't use that gear when you've just got it in drive and let it shift itself.
