2011 Jeep Grand Cherokee - Click above for high-res image gallery

Chrysler would like to sell a healthy quantity of Jeep Grand Cherokee SUVs in Europe, but the Auburn Hills, MI-based automaker knows that won't happen without a diesel option. That's why Team Pentastar will unveil a new 3.0-liter oil burner early next month at the Geneva Motor Show. The new mill packs 241 horsepower and 406 pound-feet of torque; more than enough grunt to motivate Jeep's handsome ute.

The new mill will feature Fiat's MultiJetII technology, making the new engine cleaner and more efficient, with 10 percent more horsepower and eight percent more torque than Chrysler's outgoing CRD offering. The new engine also carries a lower compression ratio of 16.5:1, which helps minimize harmful emissions. Chrysler claims that the new 3.0-liter will average 8.3 liters per 100 kilometers, while emissions will come in at an average of 218 g/km. Chrysler will also offer a detuned version of the engine, with 191 hp and 324 lb-ft of torque. This mill will enable the Grand Cherokee to be available in more markets.

Chrysler tells us that he new diesel-equipped Grand Cherokee will be available in European markets by the end of the first half of 2011. Chrysler hasn't announced any plans to offer this engine here in the U.S., sadly. Hit the jump to read over the Chrysler press release.

At the 2011 Geneva Motor Show, the all-new Jeep® Grand Cherokee will debut a new, optional 3.0-liter turbo diesel engine available for Europe and other diesel markets. The new engine is more powerful, more fuel efficient and produces lower emissions than its predecessor.

Built by VM Motori and developed together with Fiat Powertrain, a company of Fiat S.p.a., the new 3.0-liter turbo diesel engine produces maximum horsepower of 177 kW (241 hp DIN) at 4,000 rpm and torque of 550 N•m (406 lb-ft) at 1,800-2,800 rpm. This translates to 10 percent more power and eight percent more torque than the engine it replaces.

Even with its improved performance, fuel economy for the new 3.0-liter turbo diesel engine is 8.3 L/100km on the combined cycle, an improvement of 17 percent over the prior diesel engine. CO2 emissions (combined cycle) are also reduced by 17 percent, now at 218 g/km.

The V-6 turbo diesel engine is fitted with new-generation, 1,800-bar injectors with new MultiJet II technology, developed and patented by Fiat Powertrain and which made its debut in 2009 on the 1.3-liter diesel engine equipped on the Punto Evo.

Engine Block Structure
The new 3.0-liter turbo diesel engine features a compressed graphite iron, 60-degree block with aluminum cylinder heads and a two-piece structural aluminum oil pan. Bore is 83 mm (3.27 in) and stroke is 92 mm (3.62 in) for a total displacement of 2987 cm3 (182 in3). Bore spacing is 96 mm (3.78 in).

The engine is compact and lightweight, with overall dimensions of 695 mm (27.36 in) in length, 729 mm (28.7 in) in width and 697.5 mm (27.46 in) in height. Weight of the fully dressed new engine is 230 kg (507 lbs).

The engine block features a crankcase architecture with stiffened construction, including a bedplate that provides a rigid and stiff carrier for the crankshaft. This in turn helps reduce overall noise from the lower reciprocating assembly and contributes to significant improvements in overall noise, vibration and harshness.

Adding to the structural rigidity of the block, the two-piece aluminum oil pan has been designed to provide strength and contribute to the quietness of the engine. The lower pan has been reinforced for off-road use. Crankcase capacity is 7.7 L (2 gal).

Cylinder heads are constructed of aluminum and feature a chain-driven, dual overhead-camshaft design with four valves per cylinder. Intake valves measure 28 mm (1.1 in), and exhaust valves are 24.5 mm (0.96 in) in diameter. Combustion-chamber volume is 24.68 cm3 (1.51 in3).

A forged-steel crankshaft is supported by four main bearing journals fitted with four-bolt main bearing caps incorporated into the bedplate. Externally balanced, the crankshaft measures 442.2 mm (17.41 in), reducing the overall packaging requirements of the engine. Connecting rods, with an overall length of 162.9 mm (6.41 in), are constructed of cast iron.

Lightweight, cast-aluminum pistons are redesigned to provide minimal friction. The compression ratio of the new diesel engine is now 16.5:1, reduced from 18.1:1 on the previous model, contributing to cleaner combustion and providing more power.

All main bearings are a "lead free" design for reduced environmental impact during construction and later recycling of the engine.

Engine Performance Features
The induction system includes swirl control to optimize combustion. Fitted between the intake system and the combustion chamber, the swirl control effectively provides an ideal air/fuel mixture at all levels of engine speed.

Precise fuel delivery is through a 1,800-bar common-rail fuel-injection system. Thanks to the new MultiJet II technology, which makes use of a special balanced solenoid valve, the new injector is capable of making up to eight injections per cycle with the possibility of managing the two main injections in a single modular profile (IRS – Injection Rate Shaping). This guarantees a reduction in consumption and polluting emissions of approximately 2 percent compared to a traditional injector and ensures a drastic reduction in noise levels.

The new 3.0-liter diesel engine utilizes a single Garrett VGT 2056 turbocharger with variable turbine geometry. Compact and lightweight, the turbocharger provides near-instant response and includes an air-to-air intercooler.

Fuel Economy and Emissions
Fuel economy for the Jeep Grand Cherokee with the 3.0-liter turbo diesel engine is rated at 10.3 L/100 km on the urban cycle and 7.2 L/100 km on the extra-urban cycle. For the combined cycle, the fuel economy is rated at 8.3 L/100 km.

The engine is designed to run on EN590 ultra-low-sulfur diesel fuel.

For this engine, cast-iron exhaust manifolds are utilized. Additional emissions controls include a close-coupled diesel oxidation catalyst and standard diesel particulate filter. Euro 5 emissions are met through an exhaust-gas recirculation (EGR) system that includes an EGR valve with DC motor and a high-performance EGR cooler with bypass valve.

CO2 emissions are reduced to 270 g/km for the urban cycle and 188 g/km for the extra-urban cycle. Combined-cycle CO2 emissions are now 218 g/km.

Lineup
Jeep Grand Cherokee will be now offered in Europe in Laredo and Limited trim lines in addition to the Overland version. The Laredo and Limited trim lines will be available with the 3.6-liter V-6 Pentastar engine and new 3.0-liter turbo diesel, while Overland will be available for the total engine lineup.

The 3.0-liter turbo diesel engine for the new-generation Jeep Grand Cherokee will be offered in European markets also as a low-output version, with 140 kW (190 hp DIN) of power at 4,000 rpm and 440 N•m (324 lb-ft) of torque across 1,600-2,800 rpm. The low-output version of the turbo diesel engine will be standard on Laredo models (optional on Limited). This will allow Grand Cherokee to meet a wider potential market in Europe.

The new diesel engine will be available in Jeep showrooms by the end of the first half of the year and will join two petrol engines to round out the powertrain lineup.

The all-new Jeep Grand Cherokee features the first application of the all-new 3.6-liter Pentastar V-6 petrol engine. This V-6 engine with variable valve timing (VVT) delivers 210 kW (286 hp DIN) of power and 347 N•m (256 lb-ft) of torque.

The Grand Cherokee is also available with the legendary 5.7-liter V-8 petrol engine. Also with VVT, this powerful engine delivers 259 kW (352 hp DIN) of power and 520 N•m (384 lb-ft) of torque. The engine's Multi-displacement System (MDS) helps manage fuel efficiency and can cut fuel delivery to up to four cylinders under certain driving conditions.

All-new Jeep Grand Cherokee
Nearly two decades ago, Jeep reinvented the premium sport-utility vehicle (SUV) segment with the introduction of the Jeep Grand Cherokee. More than 4 million sales later, Jeep improves the formula and provides the ideal balance between iconic 4x4 capability and on-road refinement with the all-new Grand Cherokee.

The all-new Grand Cherokee delivers premium on-road performance while maintaining the Jeep brand's legendary four-wheel-drive, torque-on-demand two-speed transfer case and unsurpassed towing capability. It also offers true American craftsmanship, a sleek new exterior design, a world-class interior cabin, improved fuel economy and a host of safety and technology features.

The all-new Quadra-Lift™ air suspension system is a first for Jeep, providing a total of 105 mm (4.1 in) of lift span. Quadra-Lift features five height settings and operates automatically or may be controlled manually via console controls. In addition, the all-new Selec-Terrain™ traction control system allows the driver to choose from five driving conditions in order to achieve the best driving experience on all terrains. New front and rear independent suspension systems deliver premium on-road handling and comfort.

      When Jeep offered the last generation GC with a 3.0 mercedes diesel, (From 06-07) they weren't exactly flying off the lots. The price permium was $1000 over the hemi and it was still only rated in the low 20's on the highway. It was probably also chryslers fault for only offering it on limited and overland models. I think if it was available in laredo models with lower prices, it might have sold better.
      I drove one, and I loved it, but not at $45k. It they offered it as a stand alone option, and came in closer to $35-37k it would be a much more attractive package. Still, that doesn't present much of a business case for federalizing it.

        It was saddled with the old no ratio spread MB 5 speed automatic.

      I absolutely swear that our pleas fall on deaf ears (minus the EVO and WRX) in the auto industry. I will never understand their motives. Ever.

      If there are diesel's in America's car future, I suspect two basic engines will predominate. The VM Motori new 3.0 liter 6, and the FPT 1.3-2.0 liter I-4. GM and other EU brands, as well as Fiat, use the Fiat 2.0 liter diesel in many car brands in Europe and although the VM Motori has had little acceptance since it's relatively new, there seems to be lots of interest now that FPT has breathed its MultiJet II and rumored MultiAir on it.

      The real question is who will invest the large sums to reduce the phony "clean diesel" toxic emissions to US legal limits, some 5-9 times cleaner than what Europe will eventually allow in mid-decade, and 100-1000 times cleaner than now. Finally the EU automakers are having to clean up their supposed "clean diesels" which are nothing of the sort, in reality. Being required to do a half-assed job for their home market to meet EU V and EU VI, some have apparently said they might as well go all the way to US reduced toxic emissions of currently legal T2B5. Although they better hurry, the California clowns at CARB are already circulating a proposed regulation to tighten toxic emissions much further.

      I expect the Fiat 2.0 liter to certainly be announced for Fiat -Chrysler cars and now that they own 50%of VM Motori, to do the same for the VM Motori 3.0 liter too. GM is announcing a 2.0 liter for the Cruze, although it is unclear whether it will be the FPT 2.0 liter they use in Europe, or some other 2.0 liter diesel.

      Actually for us in the US, the 07-08 JGC came with the 3.0-liter CRD engine, built by Mercedes-Benz, produced 215 hp (160 kW) @ 3800 rpm and 376 lb.-ft. torque (510 N•m) @ 1600-2800 rpm. Its a good thing they divorced Daimler but sadly they dont want to offer their diesels anymore. Also the WK series only managed 23mpg due to its archaic 5 speed trany n 3.73 axle ratio. We love our 3.0L CRD and now even more with the tune it has. Its a brilliant machine.

      Gotta find a way to bring it here Jeep. Oh, and if you offer the same motor in the Wrangler Unlimited you'll have at least one new customer.
        • 4 Years Ago
        I'll go one step further, and after putting it in the Wrangler... Put it in the new pickup based of the Wrangler and I'll make sure to put a full deposit now!
        • 4 Years Ago
        @ QAZZY:

        You apparently missed the "detuned" part mentioned right before that. The standard figures for this engine are 241hp and 406lb-ft, right in line with what other diesels of similar size offer in similar vehicles.

        For instance:
        M-B 3.0L CDI in the M-Class - 210hp, 400lb-ft
        VW 3.0L TDI in the Touareg - 225hp, 406lb-ft
        BMW 3.0L diesel in the X5 - 265hp, 425lb-ft

        +1 on wrangler diesel, thats been needed for a long time.

        I had to see if it was worth getting a diesel being price per gallon is more than gas. For a 20mpg gas engine, and 28mpg diesel, theres a 40% improvement in mileage, but a 11% average increase in cost per gallon (here in IL anyway), which still makes a 21% decrease in cost of fuel. So the only factor is how much extra is the diesel engine when buying the vehicle, provided they sold it in the US.
        • 4 Years Ago
        320 ft/lb isn't that astronomical for a diesel, and 191 hp is pretty weak for a V6, diesel or not. Sadly, that's less than Volvo's 3.2.
        • 4 Years Ago
        There's a reason that you don't see many oil burners available in the U.S.--they don't meet the EPA's standards. Until that happens, you won't get a diesel.
        • 4 Years Ago
        Chrysler... WTH?? A diesel Grand Cherokee limited is just what I need in the states to get rid of my wife's damned CRV!! And to echo the comments... a diesel Wrangler? How many years has the US Jeep community been hungering for one??
        • 4 Years Ago
        400 ftlb! That kind of thrust is something to dream about ... especially in a 3000 lb Jeep Wrangler!

        I've heard tell of the VW 4cyl TDI engine transplanted into a Jeep Wrangler, more HP and TQ than any stock TJ, and amazing gas mileage. It's quite the process, though.

        These kinds of vehicles are BEGGING for a diesel motor, and so are the customers!
      • 4 Years Ago
      Why not offer this in the Ram 1500 as well? Seems to be the right amount of power for a half ton pickup, and you could push the development costs of emissions equipment onto several vehicles.
      • 4 Years Ago
      Are they the same people who made the Jeep Liberty Diesel? From what I heard those engines had all kinds of problems.
      • 4 Years Ago
      Damn it Chrysler! Bring us this Diesel!

      It will sell, it will sell! Put in this Jeep and the Wrangler and it will freaking sell! I will buy it!
      • 4 Years Ago
      A little over 28 MPG.
        • 4 Years Ago
        Which is quite a bit better than the gas V6.

        My 4Runner is up to 100,000 miles, and when I replace it I'd really like something the same size, with as much offroad capability (which I use), and significantly better mileage. It is really too bad that Jeep won't see fit to sell that diesel here.
      • 4 Years Ago
      The question is will we pay 50k + for this vehicle. That's what the last cherokee was going for, mind you they sold every last one of them and they never sat on the lots, so the answer must be yes. And 90% of vw touaregs are sold in TDI trim, and they're up over 50 as well.
        • 4 Years Ago
        I'm not sure where 90% of Touaregs sold are diesels, but I'm fairly certain it's not in the US.
      • 4 Years Ago
      @Stan Peterson
      EU emissions standards are similar to US ones, with one exception - NOx emision. That's the only problem for diesels. More - T2B5 (except NOx) is less strict than Euro V, cars like Mazda RX-8 or Honda Civic with ~200hp 2.0L engine couldn't meet Euro V and are out of EU market. You can still buy them in US.
      • 4 Years Ago
      The Lancia Thema (new Chrysler 300) will have the same engines (190 or 224 hp).

      In Europe, Compass and Patriot are availible with the 2.2 L CRD (163 hp, 6,6 L/100 Km), Wrangler and Cherokee (Liberty) with the 2.8 L CRD (200 hp): 7,1 to 8,1L/100 Km for Wrangler and 7,9 L/100 Km for Cherokee.

      VM Motori created diesel 2.0 L which is in euro-spec Chevrolet Cruze and Captiva.
