Chrysler Group announced the first diesel-powered, full-size sport-utility vehicle (SUV) to be offered in the United States. Along with a diesel Grand Cherokee Jeep is offering four engines and two fuel types. Unfortunately, because the Federal Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) can't agree on diesel regulations and engine regulations, so the 3.0-liter Common Rail Diesel (CRD) engine in 2WD models will not be available in ME, NY, VT, CT, CA and the 4.7-liter SOHC V-8 Flexible Fuel Vehicle (FFV) will not bevavailable in ME, NY, VT, CT, CA.
3.0-liter Common Rail Turbo Diesel (CRD):
The new 3.0-liter common rail turbo diesel (CRD) engine produces 215 hp (160 kW) @ 4,000 rpm and 376 lb.-ft. of torque (510 Nom) @ 2,000 rpm. The engine offers up to 30 percent improvement in fuel economy, class-leading torque, outstanding towing capacity (7,400 lbs.) and class-leading driving range (approximately 425 miles). And, clean diesel technology reduces CO2 emissions by an average of 20 percent. The new engine will be available starting in the first quarter of 2007.
3.7-liter SOHC V-6:
The 3.7-liter V-6 engine provides the 2007 Jeep Grand Cherokee with a powerful standard engine that is efficient, durable and smooth. It produces 210 hp (157 kW) @ 5,200 rpm and 235 lb.-ft. (319 Nom) of torque @ 4,000 rpm. A sophisticated Electronic Throttle Control system tailors throttle response to pedal movement based on operating conditions, and maintains a consistent vehicle speed on rolling grades when cruise control is active. New on the 3.7-liter engine for 2007 is an exhaust gas recirculation valve, which helps increase fuel economy.
4.7-liter SOHC V-8 (FFV):
For 2007, the Jeep Grand Cherokee with the 4.7-liter V-8 engine is flex-fuel capable. This feature gives customers the ability to use up to an 85 percent concentration of ethanol (E-85) to fuel their vehicles. The seamless transition of one fuel to another is accomplished by an advanced calibration system that determines the concentration of ethanol in the gasoline and adjusts for greatest operational efficiency. Flex-fuel vehicles (FFVs) support renewable sources of fuel and reduce emissions. The engine produces 235 hp (175 kW) @ 4,500 rpm and 305 lb.-ft. (414 Nom) of torque @ 3,600. (Not available in Maine, New York, California, Connecticut and Vermont.)
5.7-liter HEMI V-8:
The 5.7-liter HEMI V-8 is a highly refined power plant that delivers outstanding performance and reduced noise, vibration and harshness. The engine produces 330 hp (246 kW) @ 5,000 rpm and 375 lb.-ft. (509 Nom) @ 4,000 rpm. The engine gives the Grand Cherokee best-in-class power, while 90 percent of the engine's peak torque is available from 2,900 rpm through 5,100 rpm for excellent performance. The engine features the Multi-Displacement System (MDS), which deactivates four cylinders when the V-8 is not needed. Chrysler Group was the first manufacturer to offer fuel-conserving MDS in an SUV.
Available with the 3.7-liter V-6 engine is the W5A580, a five-speed automatic transmission that provides smooth shifts and optimum fuel economy. The 3.0-liter CRD engine is mated to the W5J400 five-speed automatic transmission. The 4.7-liter V-8 and the 5.7-liter HEMI V-8 engines are mated to the 545RFE five-speed automatic transmission. The W5J400 and the W5A580 have been refined for higher-quality shifts while giving Grand Cherokee class-leading towing capacity of 7,400 lbs. All transmissions feature Electronic Range Select driver interactive shift control. The shifter provides fully automated shifting when in the "drive" position. Or the driver can manually select each gear by simply moving the shifter left and right from the "drive" position. This gives the driver control to precisely match any on-road or off-road requirement.
The 2007 Jeep Grand Cherokee adds side-curtain air bags with roll-detection system as a standard safety feature. Remote start is included as standard on Jeep Grand Cherokee Limited and Overland, and optional on Jeep Grand Cherokee Laredo.
The exterior design has a high belt line and a reduced glass-to-body proportion. The signature seven-slot grille boldly dominates the front view. The Grand Cherokee Laredo features a body-color grille, while a chrome-plated grille accents the Limited.
The shape of the body is designed to protect the sides of the vehicle from potential road debris. The bodyside molding also has the integrated Grand Cherokee name. At the side, a proportionately longer hood and greater distance between the center of the front axle and the base of the windshield emphasize the engine compartment and help to achieve a more powerful image.
The interior has a rich, two-tone instrument panel treatment, door trims and upscale interior finishes.
The trim styles are different for each model: Laredo features cloth and optional leather, while Limited seats are two-tone leather with perforated inserts. Jeep Grand Cherokee Laredo adds chrome control buttons for 2007, and all models have upgraded interior appointments. The instrument panel features a dark upper color and lighter lower color. Multiple bins are available for additional storage. In the rear cargo area, versatility and storage reign. A reversible load-floor panel is carpeted on one side and offers easy-to-clean plastic on the other. The plastic side includes a large shallow tray for additional utility.
Craig Love, Vice President - Rear-Wheel Drive Product Team, Chrysler Group: "True to its Jeep heritage, the Jeep Grand Cherokee is designed to be the most capable 4x4 in its class. The 2007 Jeep Grand Cherokee offers the best of all worlds. With three full-time 4x4 systems and four superior engine offerings, the Jeep Grand Cherokee is the real thing."
For Jeep Grand Cherokee customers who want the assurance of full-time four-wheel drive without any switches or levers to pull, Quadra-Trac I is ideal. The system provides for smooth operation of the vehicle over a variety of road conditions.
The NV140 transfer case splits torque 48/52 percent (front/rear) for nearly even distribution of engine power. The single-speed transfer case has been designed to rigorous Jeep durability standards while offering smooth and quiet operation. The use of the Brake Traction Control System (BTCS) with the NV140 transfer case makes the 4x4 system extremely competent in most situations.
The Quadra-Trac II 4x4 system for Jeep Grand Cherokee gives the customer the benefit of the NV245 two-speed active transfer case and BTCS.
The NV245 transfer case is the same used in the Quadra-Drive II system. It takes input from a variety of sensors to determine tire slip at the earliest possible moment and take corrective action. The system also uses Throttle Anticipate - sensing quick movement in throttle from a stop - and takes steps to maximize traction before tire slippage occurs.
Quadra-Trac II features an electronic shift mechanism for ease of use. The transfer case offers a low range for off-road situations and includes a neutral position for trouble-free towing behind another vehicle.
The Quadra-Drive II Jeep 4x4 system offers customers the ultimate in off-road capability. It combines the NV245 full-time transfer case with Electronic Limited Slip Differentials (ELSD) for best-in-class tractive performance. The system instantly detects tire slip and smoothly distributes engine torque to the tires with traction. In some cases, the vehicle will even anticipate low traction and adjust to proactively limit or eliminate slip. The heart of the system is the NV245 active transfer case.
A key component in the Quadra-Drive II system is the ELSD - an industry-first application front/rear/center and the benchmark for automatic traction differentials. The ELSD uses electronically controlled clutch packs to automatically and instantly vary from slip to lock at each axle. This maximizes traction when needed without any of the on-road drawbacks normally associated with such a robust 4x4 system.
The Jeep Grand Cherokee CRD will be manufactured at the Jefferson North Assembly Plant in Detroit. The 3.0-liter CRD engine is built at the Mercedes-Benz Berlin Marienfelde Plant in Berlin, Germany. Pricing will be announced closer to availability. The 2007 Jeep(R) Grand Cherokee with a 3.0- liter common rail turbo diesel (CRD) engine will arrive at Jeep dealerships in the first quarter of 2007.
