So you feel that and think that if you stomp on for 5K+ it must be pretty damn quick. And it would be, if you could do that.

But with the extremely tall, widely spaced gears the only place you can have 5K+ is around 40-45 mph. Punch it on the onramp and and it gives you barely past 3K instead. Your 360 horses are nowhere to be seen.

The ML550 weighs the same and has about the same power. But it has a close ratio 7 speed. Their 2nd gear is shorter than the Jeep's 1st.

And it runs 0-60 in the low 5s and the 1/4 in 14 flat.

Gearing is every bit as important as motor. The Hemi is great. The transmission sucks.

People who drive any 5.7L Dodge are the worst.... always trying to race you for no reason. I've ran off a few ram drivers with my MKZ. At least the WK crew isn't as bad LOL

I dont know where this bashing is coming from... these are not race cars, if you want to bash a vehicle wait till its performance enhance version comes out. The originator of this post talking about "I drove up in a 335i..." and you knock this? chryslers srt8 grand cherokee has been the top dog in performance suv's since it came out. With its ancient technology non variable valve timed cam in block engine, going against hand built M series suv's and still coming out on top.

People dont buy overlands to go race civics, and corvettes, they buy them for the much more refined driving experience compaired the original WK of which it is VERY much so.

Furthermore electronic throttle control is for emissions... taking a large displacement v8, non variable valve timed and making it pass current emissions standards, unfourtunatly it takes a lazy throttle pedal and less than stellar shift points. Its a nice car, made for getting groceries and weekend trips to the mountain. When you dont drive it like a raped ape it drives VERY nice, its VERY smooth and VERY comefortable, yet when you need some umph it has some on tap for you... so long as your patient for it ha ha. I make a living repairing these, drive them day in and day out, and the change is night and day....

Lastly, sorry it wasnt up to your bmw standards, If you would like them to inflate the cost another 20k and put bmw logos on it Im sure they could work something out for you. This is an atainable, much more affordable, luxury suv.
OMG you have now became my new best friend on this site. Took the words right out of my month

I still think that with either engine choice the WK2 is a great vehicle. I look forward to getting one (with Turbo Diesel hopefully )
Sorry, my bad... I read the first page a couple days ago, and decided to bite my tongue then, today I was killin time and only read the last page and decided that I could respond in a way that was slightly less offensive than I was feeling on first read.. From there I just tried to remember who said what and didnt go back and reread. Sorry for throwing you under the bus

Glad someone agrees with me Marcus!

Re: Underwhelmed by HEMI

Turn off the MDS and use the stick shift and you can accelerate as fast as needed, if you have any driving ability whatsoever that is.

Re: Underwhelmed by HEMI

I mentioned the BMW only because the salesman shook my hand as I got out of my 335i, only to then push the V8 hard on the basis that if I like fast cars, I'll love the V8. And obviously my experience with the WK2 was a far cry from the 335i.

I also mentioned this power train is much less refined than the 335i, and I'll stick by that. Disregarding outright performance, they clearly hadn't spent the effort to tune the driving experience like they could have. Chrysler knows it too, which is why they've alluded to the 8-speed to placate critics. And they released a TSB to apparently refine the throttle response. So at least they are listening.

Re: Underwhelmed by HEMI

I dont know everything, but there are multiple reasons why new technology comes out, some of which is the fact that people dont want to pay 40k dollars for 10+ yr old techcnology. As also stated emissions, with more gears you can have the engine running at the optimum rpm more often to keep those tree huggers happy.

Ill also refer back to my add 20k dollars to the car comment. When your buying a chrysler product your not buying a bmw... but a bmw also cannot do this:



Also, did you ever drive a wk? If no, I completely understand your attitude on the subject. The WK2 is a completely different car from the WK, they have improved by leaps and bounds.

More gears is not the only answer and adds a level of complexity and cost. VVT accomplishes the efficiency with marginal frictional loss; the Hemi has a very fat and flat torque curve due to VVT which yields power, efficiency and reduced aggregate emissions for its large displacement. VVT is our modern engine tech black magic. I'd rather not have my drivetrain shift so much like I experience on the Audis (clutch pack wear & tear), but admittedly that's my old-school-guy philosophy at work.

Re: Underwhelmed by HEMI

Yes... thank you, the newer hemi engines (looks like 09+) have gone to variable valve timing using a cam in a cam like they did on the viper. I do agree this is the ticket. I have given some misinformation, my apologies.

There is still a long way to go, but chrysler is doing a great job working that direction.

Re: Underwhelmed by HEMI

The problem I have had with Chrysler (and GM) is the lack of thinking. Instead of working on the engine. Work on the gearing..... more so the transmission. Ford has worked on the transmissions 1st and look at what they are doing now. My 3.7L is a very good engine.... it would be much better if I had 6 gears. Its really something when my old MKZ and my moms SHO can move at 80 MPH and still keep the RPMs under 2K.... at 70 MPH in my Jeep I'm still over 2K and at 80, I'm at 2500. With that being said, the 3.6L really could have waited. I would have liked to see a brand wide transmission to mate with their engines THEN work on better engines. Think about the gas mileage that the 3.5s, 3.7s, 4.7s, ect would have had.....

Re: Underwhelmed by HEMI

WOW, what a great thread.

Even my wife who could care less about power liked the hemi a lot more than the v6 when we test drove them. She said it made the vehicle feel smaller, almost car like compared to the v6.

I heard some talk about a diesel and performance - are you joking. Do you really think a diesel will be faster than a hemi or even the v6? Even with 400 ft. lbs. of torque, I would bet the diesel would be sluggish at best. Every diesel I have driven was slow.
