When the time came to redesign the Jeep Grand Cherokee, Chrysler LLC’s design team jumped at an opportunity to reinvent, refine and re-establish the sport-utility vehicle (SUV) design that originally set the course for all other SUVs.
In order to achieve these goals, it was imperative that the exterior not only reflected the vehicle’s off-road capability but conveyed an attitude that would be compelling to existing owners and intriguing to potential customers. On the inside, the interior design team focused on ensuring superior quality, delivering exceptional fit and finish, providing focused attention to detail and raising the bar on customer comfort.
“The Jeep design team’s mission was to completely re-design the Jeep Grand Cherokee and re-define the meaning of Jeep luxury,” said Ralph Gilles, Vice President – Design, Chrysler LLC. “New and existing customers will be delighted by the world-class attention to detail on both the exterior and interior. The all-new 2011 Jeep Grand Cherokee confidently competes at every level of the full-size SUV segment, and in any market.”
Designers took the traditional design cues from the Jeep brand’s nearly 70-year heritage – the seven-slot grille, short front and rear overhangs, trapezoidal wheel arches – and moved them forward to create an all-new exterior design that will appeal to new and existing Jeep Grand Cherokee customers. On the inside, they upgraded materials and increased cargo and comfort space.
“Jeep is synonymous with the invention of the SUV,”” said Joseph Dehner, Vice President – Production Vehicle Design. “We wanted to take that significant Jeep design history and move it forward, while listening to our customers’ input on what they love about the Jeep Grand Cherokee. The end result is proof that Jeep has retained and solidified its rightful spot as the leader, with a vehicle that does not sacrifice off-road capability for luxury and premium amenities.”
The all-new 2011 Jeep Grand Cherokee gains almost two inches in length and almost three inches in width. As a result, customers will benefit with 15 percent more room in the cargo area and more than four inches of increased rear-seat knee and leg room compared with the previous model.
The all-new 2011 Jeep Grand Cherokee will be built at the 2.7-million-square-foot Jefferson North Assembly Plant (JNAP) in Detroit, which has been the site of Grand Cherokee production since its introduction in 1992.
In preparation for production of the all-new Grand Cherokee, Jefferson North Assembly is undergoing a 285,000-square-foot expansion to replace the existing body shop, which is part of Chrysler’s investment of approximately $1.8 billion in new vehicle programs. In addition, changes throughout paint and assembly operations will give the facility an all-new level of manufacturing flexibility for multiple product capability.
JNAP was built in 1991 and was expanded in 1999. 2. Design
Refined Aerodynamic Exterior Design
In order to achieve an efficient and aerodynamic appearance, designers spent a significant amount of time in the wind tunnel in order to improve Jeep Grand Cherokee’s aerodynamic numbers by 8.5 percent, which also reduced wind noise and improved the vehicle’s fuel efficiency.
The all-new 2011 Jeep Grand Cherokee sits higher, and has a wider stance, which gives the vehicle more of a stable and commanding presence on the road. The face of the Jeep Grand Cherokee has been simplified while preserving the traditional “Jeep shield” that contains the grille and headlamps. The chromed seven-slot grille, now sculpted into the front headlamps, is shorter in height and gives the vehicle a solid, aggressive look. The streamlined design of the headlamps is contemporary and features two-burner reflector parabolas. Fog lamps are standard on all models, and high-intensity discharge (HID) headlamps with auto-leveling are standard on the Limited and Overland models.
The lower front fascia features optional tow hooks and a bright insert. The lower air dam, set deep for aerodynamic purposes, may be easily removed in order to increase the vehicle’s approach angle, which is important for off-road purposes. Underneath the vehicle are individual aerodynamic belly pans that run the length of the vehicle.
The profile of the all-new Jeep Grand Cherokee is sculptural and athletic. A distinct undercut sits below the A-line, adding character to the side of the vehicle. Side-window graphics are blacked-out giving the vehicle a simplified and integrated look. A three-dimensional stainless steel window trim is standard on all models. The Jeep Grand Cherokee features very short and trim front and rear overhangs. Body-color mirrors and door handles are standard on the Laredo and Limited models. Chromed roof rack side rails are standard on all models.
“The Jeep design team purposely added premium exterior design cues to the Laredo model and it now shares its exterior features with the Limited model,” said Mark Allen, Chief Designer, Exterior and Interior Design Studio. “These subtle changes have a huge impact on the showroom floor.”
At the rear of the Jeep Grand Cherokee is a liftgate with a lift-glass window. The liftgate has a separate handle conveniently located, giving customers easier access when loading and unloading packages. The flipper glass is operated with a release button located below the liftgate handle and on the key fob. The lift-glass window allows easy access to the interior without having to open the liftgate – perfect for quick placement of groceries or off-road gear. A power liftgate, optional on the Limited and standard on the Overland, is a new feature.
New to the Jeep Grand Cherokee is an integrated, body-color rear spoiler that contributes to the vehicle’s aerodynamic efficiency. Taillamps are now larger in size and extend into the liftgate, and feature four back up lights that improve nighttime visibility on the ParkView™ Rear Back-up Camera. Chromed dual exhaust tips are paired with the 5.7-liter V-8 HEMI® engine.
The all-new 2011 Jeep Grand Cherokee is available in three models: Jeep Grand Cherokee Laredo, Jeep Grand Cherokee Limited and the upscale Jeep Grand Cherokee Overland.
The 2011 Jeep Grand Cherokee features four new exterior colors – Blackberry Pearl Coat, Dark Charcoal Pearl Coat, Rugged Brown Pearl Coat and White Gold Metallic Clear Coat – along with Bright Silver Metallic Clear Coat, Brilliant Black Crystal Clear Coat, Inferno Red Crystal Pearl Coat and Stone White Clear Coat.
All-new Panoramic Sun Roof
Making its debut on the 2011 Jeep Grand Cherokee is the all-new CommandView®, a dual-pane sun roof that extends from the windshield to the rear of the vehicle, allowing for perfect views both on- and off-road. CommandView is comprised of two glass panels – one at the front and one at the rear. The front panel may be opened rearward providing additional light and fresh air to first-row passengers. The rear panel, which is fixed, allows light and open viewing for second-row passengers and comes standard with a sun shade for those who may not want direct sunlight. CommandView is optional on the Laredo, Limited and Overland models. A traditional sun roof is also an option on all models.
Interior Designed for Comfort and Convenience
As the second major interior program to be produced from Chrysler’s Advance Interior Design Studio, the Jeep Grand Cherokee interior design team paid close attention to every detail focusing on quality, fit and finish and interior comfort.
“Every interior element was placed under the microscope on the all-new 2011 Jeep Grand Cherokee,” said Klaus Busse, Director – Advance Interior and Component Design, Chrysler LLC. “When customers touch any part of the new Jeep Grand Cherokee interior, they will experience softer materials, smooth edges and texturally pleasing components.”
The instrument panel is completely redesigned, and features soft-touch material with contrast stitching that is carried throughout the interior, including seats. Soft-touch material is integrated not only on the instrument panel but on customer touch points including doors, consoles and arm rests. By using softer materials, the Jeep design team was able to achieve fit and finish and lower interior noise levels.
The Jeep Grand Cherokee Overland emphasizes an unparalleled level of the authenticity of the Jeep brand, with attention to detail and hand-craftsmanship throughout. The Jeep Grand Cherokee Overland features a leather-wrapped instrument panel with real wood applications and a premium leather hand-wrapped steering wheel and shift knob. Contrast stitching is carried throughout the interior, as well as on seats. Finally, chromed trim subtlety accents the interior.
The 2011 Jeep Grand Cherokee features an all-new two-gauge instrument cluster that is surrounded by chrome, and features new back-lighting, which makes it easier to read at night. A new three-spoke steering wheel, with available power tilt-and-telescoping column with memory and heating, is optional on the Limited and Overland models. Cruise control functions are located on the front of the steering wheel while audio controls are ergonomically placed on the back of the spokes.
The center stack neatly houses the HVAC controls, radio and an electronic switch bank. Located on the bottom of the center stack is a covered bin lined with a rubber mat that is perfect for tucking away a cellular phone or any other hand-held devices.
New to the Jeep Grand Cherokee 4×4 is a Selec-Terrain switch located on the center console just behind the gear shifter. This new feature enhances an already capable and fully automatic four-wheel drive system by providing optimized traction settings to tailor the vehicle’s traction performance based on road conditions.
Located next to the Selec-Terrain switch is a covered bin featuring illuminated cup holders. The covered bin is standard on Limited and Overland models while the Laredo model features an open bin with illuminated cup holders. The center console storage houses a power outlet and iPod docking station that is capable of storing up to seven CDs or DVDs. Additional storage may be found on doors that are equipped with map pockets which also include a designated space to store a water or soda bottle.
The 2011 Jeep Grand Cherokee offers all-new seats for driver and passenger comfort. First-row seats feature molded shoulder corners giving seats a robust look. Standard on all models is an eight-way power driver seat with a four-way power lumbar, and standard on the Limited and Overland models is an eight-way power passenger seat with a four-way power lumbar. A fold-flat front passenger seat is standard on the Jeep Grand Cherokee Laredo, and 60/40 fold-flat second-row seats with recline are standard on all models. The Jeep Grand Cherokee Overland features ventilated (cooled) seats. Heated front seats are optional on the Laredo model and first- and second-row heated seats are standard on Limited and Overland models.
Aircraft-inspired LED lighting is placed within the interior cabin, map pockets, window switches and foot wells — perfect for driving or entering and exiting the vehicle at night.
Several storage and convenience features have been designed into the rear cargo area including a grated, protective floor accented with a durable and bright finish. The spare tire has a dedicated space underneath the cargo floor that also contains two removable bins ideal for storing beverages or muddy gear.

Go Anywhere 4×4 Systems
The 2011 Jeep Grand Cherokee features three 4×4 systems (Quadra-Trac I®, Quadra-Trac II® and Quadra-Drive® II).
Quadra Trac I delivers full-time four-wheel drive without any switches or levers to pull. The system provides smooth operation of the vehicle over a variety of road conditions. This light-weight single-speed case is both proven and efficient for enhanced fuel economy.
The Quadra Trac II’s two-speed transfer case uses input from a variety of sensors to determine tire slip at the earliest possible moment and takes corrective action. The system also uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before tire slippage occurs. When wheel slippage is detected, as much as 100 percent of available torque is instantly routed to the axle with the most traction.
Quadra Drive II, with a rear Electronic Limited-slip Differential (ELSD), delivers industry-leading tractive capability. The system instantly detects tire slip and smoothly distributes engine torque to tires with traction. In some cases, the vehicle will anticipate low traction and adjust in order to proactively limit or eliminate slip.
Selec-Terrain is standard with Quadra Trac II and Quadra Drive II.
All 2011 Jeep Grand Cherokees equipped with the off-road or the Quadra-Lift group are Trail Rated®. The Jeep Trail Rated badge on the 2011 Jeep Grand Cherokee indicates that the vehicle is designed to perform in a variety of challenging off-road conditions identified by five key consumer-oriented performance categories: Traction, Ground Clearance, Maneuverability, Articulation and Water Fording.

All-new Powertrain Choices in 2011 Jeep Grand Cherokee Offer More Fuel Savings, Refinement and Capability
3.6L V6 Pentastar (290 hp)
The 3.6-liter V-6 engine, part of Chrysler’s $3.6 billion powertrain offensive, is introduced for the first time in the all-new 2011 Jeep Grand Cherokee. The more fuel efficient V-6 engine features 11 percent improved fuel economy, 33 percent improved horsepower, 11 percent improved torque. Environmental-friendly design: lead-free engine, recyclable oil filter element with no-spill removable feature. “The engine team went out and benchmarked the best in V6s – your Toyotas and Hondas. Found all the elements from each of them to come up with the best V6,” said Matt Nyquist, Jeep Product Planning.
“The all-new Pentastar is the most advanced six-cylinder engine Chrysler has ever offered,” said Bob Lee, Vice President – Powertrain Product Team. “This new family of engines uses an architecture conceived with future technology growth and integration in mind.” The all-new 3.6-liter V-6 engine is an all-new design featuring double-overhead camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration.
“Our all-new engine delivers better performance and the capability Jeep customers demand.” “Similar to what we did with the HEMI® engine, our engineers used the best combination of design features and technologies to create an engine that satisfies customer requirements”. “The elegantly simple design maximizes the functionality of each design element rather than adding technology to claim a feature. The result gives our customers everything they demand from an engine today – class-leading levels of refinement, fuel-efficiency, performance and cost of ownership.”
The 3.6-liter V-6 engine design features a double-overhead cam (DOHC) and high-flow intake and exhaust ports, which in combination with VVT via dual independent cam phasing, allows optimum volumetric and combustion efficiency over the full speed and load range. This results in an exceptional, flat torque curve along with high specific power. The engine’s torque exceeds 90 percent of its peak value from 1,600 to 6,400 rpm, which provides customers with outstanding drivability and responsiveness.
The all-new 3.6-liter V-6 engine will deliver 290 horsepower (216 kW) at 6,350 rpm and 260 lb.-ft. (353 N-m) of torque at 4,300 rpm, an increase of 38 percent in horsepower and 11 percent in torque over its predecessor, while providing customers up to an 11 percent improvement in fuel economy. The Pentastar V-6 is designed to run on regular gasoline, offering a 10 percent reduction in fuel cost compared with premium fueled engines. The engine also is flex-fuel capable, offering consumers the choice of gasoline or E85 fuel.
An environmental-friendly oil filter system with optional integrated oil cooler is used to help protect the environment via incineration of the filter element. The use of long-life spark plugs and a high-energy coil-on-plug ignition system also helps reduce cost of ownership.
Refinement was a key objective for every component during the design phase of the engine and was achieved by utilizing advanced computer-aided engineering techniques. Structural, intake and exhaust areas of the engine are designed to deliver low levels of overall noise and achieve specific sound quality goals that meet discerning customer requirements. The result is a refined engine in all applications. Idle quality refinement is improved due to use of the dual independent cam phasing.
In developing the Jeep Grand Cherokee’s all-new 3.6L V6 engine, reliability and quality are assured via extensive validation testing. More than 3.3 million customer equivalent miles were accrued on engine dynamometers prior to production. Test severity was increased by 50% versus previous Chrysler V6 engines in order to accommodate high load applications such as trailer-towing.

5.7-liter HEMI® Engine (360 hp)
The all-new 2011 Jeep Grand Cherokee is also available with the legendary 5.7-liter HEMI V-8 engine. It delivers 360 horsepower (268 kW) and 390 lb.-ft. of torque (520 N-m) @ 4,250 rpm and also features VVT, which delivers performance and towing capability, as well as fuel efficiency with the Multi-displacement System (MDS).
“Our HEMI engine maintains the key architecture that makes HEMI a household name in powertrains, including Variable-Valve Timing,” said Jansen. “The HEMI continues to offer fuel economy and refinement, and maximizes performance and capability.”
The HEMI engine’s fuel-saving MDS seamlessly alternates between smooth, high-fuel-economy four-cylinder mode when less power is needed and V-8 mode when more power is in demand. This optimizes fuel economy when V-8 power is not required, without sacrificing vehicle performance or capability.
The HEMI’s VVT improves fuel economy in two ways. First, it reduces the engine’s pumping work by closing the intake valve later. Second, it increases the expansion process of the combustion event. This allows more work to be transferred to the crankshaft instead of being rejected out of the exhaust port as heat. VVT improves engine breathing, which improves engine efficiency and power.
The all-new Jeep Grand Cherokee offers unsurpassed trailer tow capability of up to 7,400 lbs. on 4×2 models when coupled with the HEMI V-8.

Provides the benefit in critical driving situations such as turns, and is valuable when driving on mixed surface conditions including snow, ice or gravel. If there is a discernible difference between driver input through the steering wheel and the vehicle’s path, ESC applies selective braking and throttle input to guide the vehicle back on to the driver’s intended path
Energy-absorbing Steering Column: The manual-adjust steering column utilizes two hydroformed coaxial tubes that can move relative to each other to allow the column to move forward for enhanced energy absorption during a crash. The power-adjust steering column employs a calibrated bending element that deforms during column stroke for optimal energy management
Enhanced Accident Response System (EARS): Makes it easier for emergency personnel to see and reach occupants in the event of an accident by turning on the interior lighting and unlocking doors after air bag deployment. Also shuts off flow of fuel to the engine
Express Up/Down Windows: One-touch powered express up/down window button located on the front driver and passenger-side door
Forward Collision Warning (FCW): Using forward-facing radar sensors, this system detects when the vehicle may be approaching another vehicle too rapidly and alerts the driver so the driver can determine what action must be taken in order to prevent the vehicle from a collision
High-intensity Discharge (HID) Headlamps: Provide approximately three times the light output of conventional reflector lamps for improved nighttime illumination
Hill-Descent Control (HDC): Allows smooth and controlled descent on rough or slippery terrain without the driver having to touch the brake pedal. Applies the brakes to each wheel individually when needed to reduce forward motion when negotiating steep grades
Hill-Start Assist (HSA): Assists drivers when starting a vehicle from a stop on a hill by maintaining the level of brake pressure applied for a short period of time after a driver’s foot is removed from the brake pedal. If throttle is not applied within a short period of time after the driver’s foot is removed from the brake pedal, brake pressure will be released
Keyless Go: When an individual enters the vehicle, electronic sensors detect if the vehicle key fob is present. The vehicle will then allow the individual to push a button to start the vehicle without having to insert the key into the ignition
Knee Bolsters: The lower instrument panel and the glove-box door are designed to properly position the occupant during impact, enabling air bags to work effectively
Navigation System: Voice-activated navigation system available with real-time traffic to provide precise guidance to destination through the use of Global
Positioning System (GPS) satellite technology

ParkView™ Rear Back-up Camera: Provides a wide-angle view of the area immediately behind the vehicle, giving the driver greater peace of mind before reversing at low speeds. Contains grid line to aid the driver when maneuvering into parking spaces or narrow areas. Also aids in lining up a trailer to the vehicle’s trailer hitch, when so equipped. The image is displayed on the navigation screen when the transmission is shifted into Reverse
Passive Entry: When an individual approaches the vehicle, electronic sensors detect if the individual is in possession of the vehicle’s matching key fob and the vehicle will unlock when the individual touches the door handle
Power Tilt-and-Telescoping Steering Column with Memory: Allows steering column to tilt and move toward or away from the driver to achieve a safe and comfortable distance from the advanced multi-stage front driver air bag, if deployed
Rain Brake Support: Uses the ESC pump to occasionally push brake pads lightly against brake rotors in rainy conditions in order to keep rotors dry
Rain-sensing Wipers: A driver convenience feature that automatically senses moisture on the windshield and activates wipers
Ready Alert Braking: Anticipates situations when the driver may initiate an emergency brake stop and uses the ESC pump to set brake pads against rotors in order to decrease the time required for full brake application
Rear Cross Path (RCP): In parking lot situations, this system warns drivers backing out of parking spaces of traffic moving toward their vehicle. It activates any time the vehicle is in Reverse. The driver is notified of vehicle(s) crossing behind the vehicle via illuminated icons on the sideview mirror and with a driver-selected audible chime
Remote (fob) Operated Windows (front windows – down only): Enable an individual to cool down their vehicle passively by opening front windows remotely Remote Keyless Entry: Locks and unlocks doors and turns on interior lamps. If the vehicle is equipped with a security alarm, the remote also arms and disarms that system
Remote Start: Conveniently starts the engine and activates key comfort settings based on ambient conditions by using the key fob while maintaining vehicle security
Rollover Crash Sensing: Senses a rollover and deploys seat-belt pretensioners and/or standard full-length side-curtain air bags as needed
Seat-belt Pretensioners: During a collision, impact sensors initiate front seat- belt pretensioners to remove slack in the seatbelt system, thereby reducing the forward movement of the occupant’s head and torso
Sentry Key® Engine Im-mobilizer: Utilizes an engine key that has an embedded transponder with a preprogrammed security code to discourage vehicle theft. When the key is inserted into the ignition, the controller sends a random number to the transponder and the engine is allowed to start. If an incorrect key is used, the engine will shut off after a few seconds
Signal Mirrors: Signal lamp built into the housing of exterior mirrors allows turn signals to be viewed from the front, as well as the sides and rear of the vehicle in order to alert oncoming traffic and pedestrians
SmartBeam® Headlamps: Headlamp system adjusts to ambient light and oncoming traffic to deliver maximum lighting
Standard Full-Length Side-Curtain Air Bags: Extend protection to all outboard front- and rear-seat passengers. Each side air bag has its own impact sensor that autonomously triggers the air bag on the side where an impact occurs. This type of air bag is housed in the headliner just above side windows
Standard Seat-Mounted Side Thorax Air Bags: Provide enhanced protection to the driver and front outboard passenger in certain impacts. Each side air bag has its own impact sensor that autonomously triggers the air bag on the side where an impact occurs. Standard side air bags are housed within the outboard side of each front seat
Three-Point Seat Belts: Front outboard seating positions and all rear seating positions have lap and shoulder belts
Tire-Pressure Monitoring (TPM): Informs driver when tire pressure is too low. Pressure-sensor modules within the valve stems of all four road wheels send continuous radio-frequency signals to a receiver and the system
Trailer-Sway Control (TSC): Reduces trailer sway and improves handling in adverse towing conditions caused by crosswinds and traffic. The system monitors the vehicle’s movement relative to the driver’s intended path, then applies alternating brake pressure to slow the vehicle and then increases the pressure on one front wheel in order to counteract the sway induced by the trailer

Quality
Quality Built Into All-new 2011 Jeep Grand Cherokee
More than 7.5 million customer-equivalent miles to be logged by Jeep engineers for durability and reliability
More than 3.3 million customer-equivalent miles recorded on engine dynamometers prior to production
244 hours of wind noise and aerodynamic evaluations
Every facet of the development of the all-new 2011 Jeep Grand Cherokee was aimed at addressing quality and reliability.
“Excellence comes through the execution of a well-thought-through plan,” said Doug Betts, Vice President – Chief Customer Officer, Chrysler LLC. “Our all-new 2011 Jeep Grand Cherokee is a solid example of a well-thought-through plan properly executed.”
Engineers will conduct approximately 7.5 million customer-equivalent miles for durability and reliability testing of the all-new 2011 Jeep Grand Cherokee. Testing and validation in various climates include road trips to a variety of locations including Yucca, Arizona, Baudette, Minn. and Morgantown, West Virginia. A full battery of lab testing will include full-frame fatigue testing, door-slam testing and a road-test simulator.
The 2011 Jeep Grand Cherokee has gone through more than 244 hours of wind noise and aerodynamic evaluations in Chrysler LLC’s state-of-the-art aerodynamic and acoustic test facility in Auburn Hills, Mich.
Reliability and quality were achieved through extensive validation testing in developing the Jeep Grand Cherokee’s all-new 3.6-liter V-6 engine. More than 3.3 million customer-equivalent miles were recorded on engine dynamometers prior to production. Severity testing was increased 50 percent versus previous Chrysler V-6 engines in order to accommodate high-load applications including trailer-towing.
The reduction of noise, vibration and harshness (NVH) was a key objective for every component during the design phase of the engine and was achieved by utilizing an advanced computer-aided engineering technique.
The use of a Quality Assurance Fixture (QAF) assures a high level of compliance at the start of production. The QAF allows engineers to look at the interior of the vehicle on a “simulated perfect body” which is a milled aluminum shell where all attachment points are matched exactly to CATIA modeling earlier in the program. This allows changes and design improvements earlier in the manufacturing process.
The company also employs techniques of Design for Six Sigma (DFSS), which is folding in “voice of the customer” data along with lessons learned to ensure that every vehicle is of the highest quality. The all-new 2011 Jeep Grand Cherokee is the first new vehicle to have more than 100 DFSS projects.
“We focused on perceived quality of the Jeep Grand Cherokee and worked with J.D. Power and Associates to address customer satisfaction and quality efforts through early evaluations of initial vehicles,” said Betts. “We plan to execute this vehicle flawlessly by effectively responding to the voice of the customer.” 8.
