New York Auto Show: 2011 Jeep Grand Cherokee

Article by Christian Andrei, on April 6, 2009

As we said, Chrysler unveiled today at this year's New York Auto Show the brand new 2010 Jeep Grand Cherokee which will come as an 2011 model. As you can see from the photos, the new SUV comes with a completely new face but also with a new rear showing that the American manufacturer wants to break all the sales records with this new car.

Under the hood of the new Grand Cherokee features the all-new flexible fuel 3.6-liter V6 engine capable to develop 280 hp (209 kW) and 260 lb.-ft. of torque (353 Nm) at 4,800 rpm. The all-new 2011 Jeep Grand Cherokee's larger fuel tank, with a 24.6 gallon capacity, combined with the V-6 engine's improved fuel economy, delivers a range of approximately 500 miles on one tank of gas.

The vehicle will also feature the legendary 5.7-liter HEMI V8 engine delivers 360 hp (268 kW) and 390 lb.-ft. of torque (520 Nm) at 4,250 rpm. With the front air dam removed, and the available Quadra-Lift air suspension, the all-new Jeep Grand Cherokee features a 35.9-degree approach angle, (compared to 32.3 on current model), a 29.2-degree departure angle (compared to 27.5 on current model) and 25.1-degree breakover angle (compared to 20.4 on current model).

Also, the SUV features the go-anywhere 4x4 systems: Quadra Trac I delivers full-time four-wheel drive without any switches or levers to pull. The system provides smooth operation over a variety of road conditions. This light-weight single-speed case is both proven and highly efficient for enhanced fuel economy.

Quadra Trac II's two-speed transfer case uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire 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, coupled with the all-new Quadra-Lift air suspension, offers drivers an adjustable suspension span that delivers legendary Trail Rated® performance.

With the front air dam removed, and the available Quadra-Lift air suspension, the all-new Jeep Grand Cherokee features a 35.9-degree approach angle, (compared to 32.3 on current model), a 29.2-degree departure angle (compared to 27.5 on current model) and 25.1-degree breakover angle (compared to 20.4 on current model).

The all-new independent front and rear suspension features isolated front and rear suspension cradles. Variable-rate rear springs deliver improved on-road handling and comfort that complements the vehicle's off-road capability. The new rear suspension allows the spare tire to be stored inside the vehicle as opposed to underneath.

Go-Anywhere 4x4 Systems

The 2011 Jeep Grand Cherokee offers three 4x4 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 over a variety of road conditions. This light-weight single-speed case is both proven and highly efficient for enhanced fuel economy.

Quadra Trac II's two-speed transfer case uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire 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.

Jeep Trail Rated®

All 2011 Jeep Grand Cherokees equipped with either 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 has been 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.

Jeep Trail Rated is a unique methodology used by Jeep Engineering to measure and predict off-road performance for all Jeep vehicles. Through a combination of natural and controlled field tests, Jeep Trail Rated provides a consistent measurement of off-road performance for all Jeep vehicles. Only Jeep vehicles are Trail Rated.

Powertrains

The all-new 2011 Jeep Grand Cherokee is available with two leading engine options for North American markets.

The 2011 Jeep Grand Cherokee's standard engine is an all-new flexible fuel 3.6-liter Pentastar V-6 engine. The 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. It features Variable-Valve Timing (VVT) and delivers 280 horsepower (209 kW) and 260 lb.-ft. of torque (353 N•m) @ 4,800 rpm. This all-new Pentastar V-6 engine improves fuel economy up to 11 percent compared to the previous Jeep Grand Cherokee equipped with a V-6. It is coupled with the proven W5A580, a five-speed automatic transmission that delivers smooth shifts and optimum fuel economy. The five-speed W5A580 transmission includes adaptive electronic control or Electronic Range Select (ERS) driver-interactive manual control and an electronically modulated torque converter clutch.

The all-new 2011 Jeep Grand Cherokee's larger fuel tank, with a 24.6 gallon capacity, combined with the Pentastar V-6 engine's improved fuel economy, delivers a range of approximately 500 miles on one tank of gas.

The available legendary 5.7-liter HEMI® V-8 engine delivers 360 horsepower (268 kW) and 390 lb.-ft. of torque (520 N•m) @ 4,250 rpm. The HEMI also features VVT, which delivers performance and towing capability, as well as fuel efficiency with the fuel-saving Multi-displacement System (MDS).

For international markets, the all-new 2011 Jeep Grand Cherokee will be available in left- and right-hand drive with either diesel or petrol powertrains.

World-class Interior Refinement

The all-new interior is elevated to that of its European competition and features rich materials and elegant appointments, as well as more room for both passengers and cargo.

"Following in the footsteps of our all-new 2009 Dodge Ram, our all-new Jeep Grand Cherokee is another proud graduate of our Advanced Interior Design Studio," said Ralph Gilles, Vice President - Design. "We achieved a world-class interior by using fine materials and maintaining a laser-attention to details."

An available all-new CommandView® dual-pane sun roof provides twice as much glass surface than a standard sun roof and extends from the windshield to the rear of the vehicle. The front panel can 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 power sun shade.

Right-sized Packaging

The vehicle's 114.8-inch wheelbase is 5.3 inches longer than the model it replaces and contributes to an overall vehicle length that is 1.8 inches longer than the prior model. The longer wheelbase creates more interior room and gives passengers an additional 4 inches of rear-seat knee and leg room. The vehicle also is 3 inches wider for improved handling and packaging.

Larger front door openings (1.9 inches wider; 2 inches higher) and rear doors open 78 degrees compared to current models (67 degrees) for better access to the interior.

Inside, premium seating includes room for five passengers. An available fold-flat front-passenger seat provides improved cargo storage room (Laredo models).

For added passenger comfort, rear seats recline 12 degrees. There also is a 12-degree forward angle to allow 24 degrees of variation.

Cargo volume behind the second-row provides an additional 6.8 cubic feet of room (36.3 cubic feet total) compared to the previous model. The well-appointed rear cargo area includes a storage unit with a rechargeable flashlight and new and improved grocery hooks on both sides. The spare tire compartment includes removable dual storage bins for secure storage of muddy gear or other items.

An all-new power rear liftgate is available for effortless remote up/down convenience.

Classic Exterior Design

Every surface of the all-new Jeep Grand Cherokee is new and treated for aerodynamics. This improves fuel efficiency and puts more fluidity into the design while delivering a 7- percent improvement in drag compared with the current model. The all-new 2011 Grand Cherokee Cd is approximately 0.37 compared with the 2009 Cd of 0.404.

"Our all-new 2011 Jeep Grand Cherokee is much more refined, focused and sportier than the model it replaces," said Gilles. "It has classic Jeep Grand Cherokee styling with sculpted athletic exterior refinements for 2011."

The front includes Jeep's classic seven-slot grille, round headlamps and trapezoidal wheel arches. The removable lower front fascia delivers improved fuel economy, on-road performance and off-road capability. The lower front fascia features a large chromed appliqué (Limited and Overland models) that showcases available tow hooks.

From the side, Jeep Grand Cherokee features an athletic, muscular profile. Black appliqués on B-pillars give the day-light opening (DLO) an aerodynamic, modern appearance and a sleek profile. Available chromed mirrors and door handles add to the profile and complement the full-chromed DLO surround on all models.

Seventeen-inch wheels are standard and deliver off-road capability, with optional 18-inch and all-new to Jeep, 20-inch wheels for 2011.

Taillamps wrap from the rear quarter panel to the back of the vehicle and create a solid form which achieves more of an upscale appearance. The treatment complements the front-end design and resonates with the rest of the exterior.

Jeep Grand Cherokee models equipped with a HEMI V-8 engine have 3.5-inch dual chromed exhaust tips, and those with the Pentastar V-6 engine have a 3-inch single exhaust.

Premium Performance

Continuing to build on the Jeep brand's legendary off-road capability, the all-new 2011 Grand Cherokee adds premium on-road performance to complete the package.

The all-new 2011 Jeep Grand Cherokee's premium SUV on-road manners and legendary Jeep ruggedness is achieved with more than 5,400 welds in the body alone. Torsional stiffness is 146 percent more than the current Grand Cherokee and stiffer than the BMW X5 and Toyota Highlander for improved durability and reduced noise, vibration and harshness (NVH).

With more than 3,700 mm of arc welding and 100 m of structural adhesive to augment welding, this marks a 53-percent increase in spot welds, a 42-percent increase in arc welds and a 38-percent increase in structural adhesive.
