Conclusion,The 2011 Jeep Grand Cherokee is all Jeep, outside and in, and ruggedly handsome

The launch of the new Grand Cherokee marks the first application of company's new, flexible fuel 3.6-liter Pentastar V6 engine, which features Variable-Valve Timing, 290 horsepower and 260 lb-ft of torque at 4,800 rpm.

Also available is a 5.7-liter Hemi V8, generating 360 horsepower and 390 lb-ft of torque at 4,250 rpm. The Hemi features VVT and fuel-saving Multi-displacement System (MDS) technology with dual exhaust to maximize efficiency.

Torsional stiffness is 146 percent more than the previous Grand Cherokee, and stiffer than the BMW X5 and Toyota Highlander, according to Chrysler. The Quadra-Lift air suspension system delivers off-road capability along with the new Selec-Terrain system that allows the driver to choose the drive system that best matches on- or off-road conditions. New front and rear independent suspension systems deliver better on-road handling and comfort, the company claims. Quadra-Lift adds up to 4.5 inches of lift span that is supported by four-corner air springs that provide a cushioned, premium ride. Quadra-Lift operates automatically, or may be controlled manually via console controls.

The interior has been revamped with better materials and overall aesthetics. An available all-new Command View 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.

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 also 3 inches wider. The front doors have larger openings -- by about two inches in height and width -- while the rear doors open wider-- 78 degrees versus 67 degrees -- for improved access to the interior.

Seventeen-inch wheels are standard and deliver off-road capability, while optional 18-inch and 20-inch wheels can be ordered.

The standard UConnect Guardian will automatically call emergency services in the event of an accident. Other features include remote door unlocking, roadside assistance, a stolen vehicle locator, and an emergency call feature. UConnect Web mobile internet will also be on offer.

Standard safety features include Electronic Stability Control (ESC), Electronic Roll Mitigation (ERM), four-wheel Anti-lock Brake System (ABS) with rough-road detection, and the four-wheel Brake Traction Control System (BTCS). Other safety features include full-length side-curtain air bags which extend protection to front and rear outboard passengers, seat-mounted side thorax air bags that enhance protection for the driver and front passenger and active head restraints which deploy in the event of a rear collision.

The all-new Jeep Grand Cherokee also features SIRIUS Travel Link, offering up-to-the minute information about gas prices, weather conditions, sports scores and movie listings. In addition, Grand Cherokee features SIRIUS Traffic, which monitors traffic in 78 markets across the U.S.
