The 2011 Jeep Grand Cherokee – the pride and joy of Chrysler at the moment – is just now hitting dealerships, but the automaker is already hard at work on a high-powered SRT-fettled version of its new sport 'ute. In the past, the Grand Cherokee SRT8 has always been a guilty pleasure of ours, if only for the rocket-like 6.1-liter Hemi V8 underhood.
Good news then that Chrysler is prepping an all new 6.4-liter Hemi for use in its SRT products, and we're anxious to see how this new engine works in the Grand Cherokee application, which seems likely to hit as a 2012 model.

Early reports suggested that it could be good for around 450 horsepower, but spy photographers are saying that we could see over 500 raging stallions coming out of this new monster mill. This means the new Grand Cherokee SRT8 could rip off 0-60 times in under five seconds, and we might have a truly worthy American competitor for the Porsche Cayenne Turbo, AMG-badged Mercedes-Benz ML and BMW X5 M. Here's hoping.

      This is such a sweet truck. I do kinda think they should work on getting more hp/l instead of ever increasing displacement and hiding the engines real consumption with transmission.

      Direct injection and a turbo anyone?
      • 4 Years Ago
      This is sick. I want one. Oh wait, it sux coz Chrysler has the balls to build something like this and the Toyota and Honda luvers get all bent outta shape coz its not fuel efficient. Go buy that disgusting looking hybrid from Toyota, Honda or whatever so I can blow ur doors off while pointing and laughing at you douch bags.

      The front fenders make those front wheels look puny! Looks like it need to sit lower or get a little higher profile rubber on there.
      • 4 Years Ago
      Wow that engine is huge! I wonder how heavy it's going to be, and how heavy the entire car will be.

      Definitely looking forward to those performance numbers...
        • 4 Years Ago
        I like it. I just hope those are mule wheels. They are tiny.
        • 4 Years Ago
        I would imagine any parts on the SRT engine will be lighter than their standard fare Hemi parts, so I can't imagine the engine itself will be any heavier. The transmission and rear differential might be beefier though, but it gets the lighter T-case. No real weight gain.
        • 4 Years Ago
        Increasing the cubic inches of an engine doesn't necessarily increase the weight of the engine. Drill a bigger hole (larger bore), longer stroke crank (a bit more weight) but nothing noticable.
        Hemi's have big heavy valve trains that make for big vavle covers - not necessarily weight.
        • 4 Years Ago
        "I wonder how heavy it's going to be, and how heavy the entire car will be."

        Keep in mind the engine is pushrod, so it is smaller and lighter than a similar power DOHC engine, despite the internal volume.

        Now the weight of car is another story...
        • 4 Years Ago
        Practicality be damned. Ill take it.
      • 4 Years Ago
      Yep, a 500 horsepower V8 is exactly what Chrysler needs to portray a green image right now. Especially in light of their class loosing fuel economy in just about every single product. Government money well spent...
        • 4 Years Ago
        Go whine somewhere else Techy. You can take your "Green image" elsewhere
        • 4 Years Ago
        Subaru is a joke. They have been getting better over the years, but they will never match the output of Chrysler, or most any other manufacturer around. Not because Subaru produces low quality products, they just lack the bread and butter TRUCKS and SEDANS which are necessary to compete in the market. The only Subarus I see on the road are the turbo WRX's, usually driven by 21 year old kids, which fall into the "niche" market just like you said.
        • 4 Years Ago
        The market for this vehicle? Or do you mean niche.

        Chrysler needs products with mass appeal unless it is a broad niche like Subaru has across their entire lineup.
        • 4 Years Ago
        Go bite the green one, Techy. This forum is not for you granola munchers.
        • 4 Years Ago
        I totally agree with ya TechySpecy. Chrysler is WAY behind. Where's the phoenix v6? ( which won't match up with ford/gm's new v6's but will at least be an improvement ), and what are the plans for upgraded v8's? I don't see any, other than basically adding displacement for more power, which is absolutely not the way to go. Old thinking!!

        How the hell are they going to make their CAFE numbers in the next few years?

        Where's the multiair?

        They either have basically no engine R&D budget or are not thinking ahead at all.
        • 4 Years Ago
        A Kia Sporento v. Jeep GC??? Apples and oranges, buddy, apples and oranges...
        • 4 Years Ago
        Have you ridden in a fully loaded Sorento with two tone leather seating and a panoramic Sunroof? Have you used the voice activated navigation, or listened to the 12 speaker Infinity sound system? Have you read the reviews? Have you seen that one of these can be had for less than $30K fully loaded. Have you seen that they are a top safety pick? Have you discovered that Kia and Hyundai have had steady sales increases every year? Have you seen that they now make some of the most fuel efficient vehicles available for sale?

        How about Chrysler... Oh yeah, they have some of the most unsafe, unreliable, uneconomical, inefficient cars out there, with cheap outdated interiors, and my tax dollars own them.

        That's Awesome!

        P.S. Do you know that a comparable Jeep G.C. costs almost $10K more than a comparable Sorento? When do the $5000 rebates start?

        GM deserved to be bailed out, Chrysler deserved to died instead of prolonging it's inevitable spiral towards death.
        • 4 Years Ago
        They are banking on the performance-car halo effect. They don't intend to manufacture or sell that many. It's just an excitement builder to get people into the showrooms.

        When Nissan killed off the 300zx, it almost killed the entire company because fuel sippers are generally boring.

        Chrysler does need to put some serious R&D into better fuel economy though.
        • 4 Years Ago
        Not everyone wants a greenie-weenie car that goes from 0-60 in three days. I am looking forward to the new Challenger with the 500hp, 6.4L engine. Zoom-Zoom.
        • 4 Years Ago
        Money almost as well spent as the funds directed towards our great education system which teaches our fine citizens the difference between "lose" and "loose."

        It's good to see that George Bush's program of promoting the invention of new words, which was terribly misunderestimated by those on the left, has succeeded, leading to your masterpiece, "loosing."

        Am I being too harsh? I'll stop :(
        • 4 Years Ago
        Clever.

        I guess it's easy to make a comeback that simple when you have no idea what you are talking about.

        The capability or design of the vehicle means nothing to you I gather?

        Neither the Sorrento nor Santa Fe have anywhere near the capability of the Grand Cherokee. The Borrego is the only one(from Hyundai/Kia) that even comes close.

        Let's look at some specifications again:
        Santa Fe:
        Towing - Max. 3500lbs with the V6, 1,650lbs with the 4cyl.
        Design - FWD with AWD option, no low range
        Curb Weight - 4100lbs (for a Limited V6 AWD)
        Wheelbase - 106.3in.
        Overall Length - 184.1in.

        Sorrento:
        Towing - Max. 3500lbs with the V6, 1,650lbs with the 4cyl
        Design - FWD with AWD option, no low range
        Curb Weight - 3,900lbs(for an AWD 4cyl model, website says TBD for V6 version)
        Wheelbase - 106.3in.
        Overall Length - 183.9in.

        Borrego:
        Towing - Max. 7,500lbs with the V8, 5,000lbs with the V6
        Design - RWD with full-time 4WD available including low range
        Curb Weight - 4,600lbs(on the high end for a V8 4WD)
        Wheelbase - 114in.
        Overall Length - 192.3in.

        Grand Cherokee:
        Towing - Max. 7,200lbs with the V8, 5,000lbs with the V6
        Design - RWD with full-time 4WD option including low range
        Curb Weight - 4,800lbs (on the high end for V8 4WD)
        Wheelbase - 114.8in.
        Overall Length - 189.8in.

        Look those specs over and tell me honestly which of those 3 the Grand Cherokee best competes with.

        Yes, the Grand Cherokee is unibody while the Borrego isn't, but unibody designs can be made with increased capability in mind. Neither the Santa Fe nor Sorrento are built with towing or off-roading in mind clearly. To be fair, the previous generation Sorrento was body on frame and had a low range, but the current one(2011MY) switched to a unibody construction and there is no low range.

        If you still think it's either the Santa Fe or the Sorrento, you have no idea what you are talking about(which is already quite evident). They are not designed for even remotely the same audience and they are only comparable in clueless minds such as yours.

        Please explain why you think that the Grand Cherokee is comparable to the Santa Fe and Sorrento other than the fact that all 3 are unibody. I'm patiently awaiting your well thought out response.
        • 4 Years Ago
        Are you implying that I'm a redneck?

        You just mentioned a KIA and a Hyundai SUV. First of all, the only reasons why those are built here are because of cost and union issues. Second of all, very few people in the affordable luxury SUV market will choose a KIA or Hyundai SUV over a Grand Cherokee and if they do, it's because of the pricepoint only. KIA and Hyundai are still considered to be a joke amongst most informed car shoppers. Like I said, the only reason somebody would choose a KIA or Hyundai SUV over a Grand Cherokee is simply because of the much lower price. Almost everybody would rather have a Grand Cherokee.
        • 4 Years Ago
        quote from TechySpecy: - "Even the comparable in size Kia Sorento V6 (made in Georgia) and Hyundai Sante Fe V6 (made in Alabama) are able to pull 20/26 mpg on the EPA cycle. The RWD V6 Cherokee gets 16/23 with a BRAND NEW engine." -

        Wow, talk about apples to oranges.

        The Kia Borrego is the competition to the Grand Cherokee, not the Sorrento. The Sorrento is FWD-based and is an on-road crossover with a 2,000lb towing capacity.

        The Borrego is RWD-based, has a V6 and a V8 option, is body on frame, and has a 5,000lb towing capacity. Way to overlook the obvious competition there.

        For what it's worth, the V6 2wd Borrego achieves 17/21/18 from the EPA to the V6 2wd Grand Cherokee's 16/23/18.

        If you want to compare V8's, the 2wd Borrego achieves 15/22/18 while the 2WD Grand Cherokee achieves 14/20/16.

        The Santa Fe is comparable to the Sorrento and Hyundai has no comparable vehicle to the Grand Cherokee like the Borrego is.

        Go bite the green one, Techy. This forum is not for you granola munchers.
        • 4 Years Ago
        That's what the Fiat Mulitair and Pentistar V6 engines are for. I'm very interested in what kind of mileage the Pentistar is going to result in for the new Charger and 300.

        This though, this is just for fun!
        • 4 Years Ago
        Yeah, I'm sure lots of people are going to look at the "Halo" SRT-8 and go buy the 3.6L V6. I'm sorry, the "Halo" theory only works on sports cars like the Mustang, Camaro, and Carrera's.

        Chrysler is doing the same old thing they've been doing. Isn't the definition of insanity doing the same thing over and over and expecting a different result. The 3.6L penta-crap doesn't even deliver anything other than acceptable numbers. It needs to exceed expectations if Chrysler ever plans to gain needed market and stay viable.
        • 4 Years Ago
        Drive up north. I bet you live in a southern area.

        Aside from that, nobody has yet to contest that this product is a part of a niche. Yes it is leaps and bounds better than its predecessors, but there isn't a single thing that makes this a mass market winner. Even the comparable in size Kia Sorento V6 (made in Georgia) and Hyundai Sante Fe V6 (made in Alabama) are able to pull 20/26 mpg on the EPA cycle. The RWD V6 Cherokee gets 16/23 with a BRAND NEW engine.

        People that need the offroad capability will look past this, people that just want a great family CUV with room to spare will pass.

        Pathetic...

        ======================
        Though you might think that Chrysler didn't deserve to "live," for the many of the employees of the company they will have jobs tomorrow and from the looks of it, for many years to come. My sense is that you'll be eating crow in a year. From the spy photos and leaks Chrysler is making a come back - The GC is a perfect example of this. I've seen many on the streets of DC and this is an IMPORT CITY TOWN.

        Cause and effect - if a company dies, the effect is many people will be unemployed - GEE... that sounds the right thing to do. The employees of Chrysler are earning their paychecks and not being given a handout. Right now they may not be building a product you would consider, but a few months from now it will be a different story.

      "...we could see over 500 raging stallions coming out of this new monster mill."

      Really?
        • 4 Years Ago
        It'd be a pretty poor effort if they don't get 500HP out of it.
      • 4 Years Ago
      No center exhaust? Preposterous.
        • 4 Years Ago
        Maybe because they will allow this SRT8 model to tow.

        The last one had the center exhausts so a trailer hitch couldn't easily be added.
        • 4 Years Ago
        I'm really gonna miss the center exhaust, it gave it an instantly recognizable performance attribute. People were crybabies about using a tow hitch attachment, for a vehicle that had less towing capacity than the regular hemi V8.
      • 4 Years Ago
      The srt8 cherokee has been my favorite chrysler product for some time. It's quick and it's useful.
      Other than the viper, but that's pretty much unobtainable for the average guy.


      With that said, i'm not loving this new one.
      I pray there is no chrome on the outside, none meaning zero, not the grille, trim, door handles, or even the rims.
      Something about it, just doesn't look as mean as the previous model.
      • 4 Years Ago
      Instead of doing engines with more and more displacement, I would rather see them try to extract more hp out of engines of the same size as before
        • 4 Years Ago
        Ditto, aka what Ford is doing. And look at the response to the new F150 engine lineup.

        Not sure why people are rating you down here.
        • 4 Years Ago
        They're doing both. The base engine for the 2011 GC, the engine over 80% of these things will have, is the new pentastar 290HP 3.6L V6. It replaces the old 210HP 3.7L V6. The new engine get's about 13% better gas mileage in a slightly heavier vehicle, even with the extra 35% power.
      • 4 Years Ago
      Someone threw a different set of wheels on a Limited.
      That is no way an SRT8
      Nice try
      • 4 Years Ago
      OK this what I hate...
      my guess is that this vehicle is going to be able to put a smack down on Cayennes and X6s and Range Rovers, but even if it has an interior worthy of its price and on-par build quality, all the car mags are still going to bitch and complain about how much this SUV costs even though they NEVER question the absurd prices for Porsches and BMWs.
        • 4 Years Ago
        You've got a point, they may

        Hopefully they'll put aside any prejudice and judge it on it's own merits, all things considered.
        • 4 Years Ago
        I've never read a car mag complain about the price. Outside of the interior it's always been good in comparison to the Cayenne. It will be interesting to see how the 8speed stacks up with 500hp. I'm gonna guess hwy mileage to break into the 20s.
        • 4 Years Ago
        Good point.
        • 4 Years Ago
        @ ROCKandREVIEWcom

        I am not even talking about JUST this JGC SRT8 either.

        I am talking about almost any higher-end American car. The Germans, Italians, English and to a lesser extent the Japanese can charge pretty much anything they want, and most of the car mags will gush over them as if price was no object... yet you get a highly-optioned American car and immediately it's over-priced. WTF? They pulled that stunt when the new Taurus came out just recently.

        It's a nice big sedan with good power and nice quality and styling and they kept on focusing on the damn price. If it had a 3-pointed star or a blue and white rondel on the hood, it would have cost $10, 20 or even 30k more and no one would have batted an eye.

        I unfortunately see the same crap happening with this SRT8 when it will no doubt be matched up against off-roaders from RR and Mercedes. They will say that "it's good for it's price" and then not bat and eye at a Cayenne Turbo that might cost almost 2X as much.

        Now I am not trying to make excuses for poor-quality cars that just happen to have a big fat engine in the front, but some of these newer American cars really can compete with the best of the best and yet they still rarely get a fair shake.


        -sorry for the rant, but I know this SRT8 is going to be rather pricey and I am just anticipating the same stupid arguments on how a Jeep "shouldn't" cost $X, but it's perfectly fine if a Porsche SUV does $2X.
