2005 Jeep Grand Cherokee HEMI

The 5.7-liter Hemi V-8 engine replaces the 4.7 liter High-Output V8, providing best-in-class power along with better gas mileage, thanks to the multi-displacement system which shuts off half the cylinders when they are not needed. The speed of the system (switching in .04 seconds) makes its operation imperceptible, while raising gas mileage by up to 20% - and that's in addition to the increase coming from the Hemi's more efficient design. 90% of peak torque is available from 2,400 to 5,100 rpm. Electronic Throttle Control (ETC) system tailors throttle response to pedal movement based on operating conditions, and maintains more consistent vehicle speed on rolling grades when cruise control is active than the former mechanical throttle control system. In the Grand Cherokee, the Hemi has been tuned to 325 horsepower and 370 lb-ft of torque - more torque and less horsepower than in Ram trucks and LX cars.

Engineers were challenged with the task of designing a Jeep suspension that performs better off-road, matches or surpasses existing durability and vastly improves vehicle handling and ride comfort on-road. The solution: Combine the five-link rear suspension architecture with an all-new Jeep Grand Cherokee short-and-long-arm (SLA) independent front suspension (IFS).

We designed the all-new front suspension for improved off-road performance and robustness," said Eric Ridenour, Executive Vice President -- Product Development. "Simultaneously, we achieved a vast improvement in handling and ride comfort. The five-link rear suspension was tuned for superb handling and balance in a package that will be just as fun and enjoyable to drive every day on the pavement as it is off-pavement."

"Jeep is the only company that holds its engineers to such high standards for off-road capability and durability -- AK3 and Jeep Trail Rated® -- and can still deliver world-class SUV ride and handling performance," said Craig Love, Chrysler Group Vice President Activity Vehicles.

Nodular iron, single-piece lower control arms feature an L-shaped geometry designed to provide higher ground clearance at the wheels than most IFS systems. Forged upper control arms provide strength and durability. Tall aluminum steering knuckles provide optimal steering and suspension geometry for excellent on-road handling and maneuverability. Coil-over shocks deliver high-performance control.

Front suspension travel is increased by almost 10 percent (more than one inch) compared to the 2004 Grand Cherokee, further improving the 2005 Grand Cherokee's off-road capability.

The advantages of this front suspension include much improved handling, reduced head toss on and off road for a more comfortable ride, a savings of 100 pounds of unsprung mass, more precise steering, and a lower center of gravity.

The 2005 Grand Cherokee rear suspension builds on the success of previous generation Jeep multi-link systems. Four tubular control arms combine with a tubular track bar for total rear-axle control. The shock absorbers are positioned more vertically than in past models for greater body control and reduced head toss.

The spring rates and shock dampening have been tuned to complement the front suspension for a highly balanced chassis.

Grand Cherokee's new rack and pinion steering system imparts a more precise steering feel translated to the driver through fewer linkages than a recirculating ball steering system.

I drove one of these last weekend, out at Spruce Meadows you could test drive the Grand Cherokee, Magnum, Crossfire, and 300. The Grand Cherokee was by far my favorite - the interior is nicely done, especially with the GPS and DVD player! They had a little track you could drive on, and the Grand Cherokee drove like a dream.

They didn't mention anything about price, but after driving one I'm hooked for sure. I plan on getting one of these in the spring.:drool:
