Used 2017 Jeep Grand Cherokee Summit

The 2017 Jeep Grand Cherokee is available in six trims: Laredo, Limited, Overland, Trailhawk, Summit and the high-performance SRT. All but the SRT feature a standard 3.6L Pentastar V6 engine that makes 295 horsepower and 260 ft-lb of torque. The flexible-fuel engine features variable-valve timing and lift as well as auto-stop/start technology and is mated to an 8-speed automatic transmission. Limited, Overland and Summit models offer an optional 3.0L EcoDiesel V6 with 240 horsepower and 420 lb-feet of torque. The engine achieves up to 30 mpg on the highway and gives Grand Cherokees so equipped an effective range of up to 730 miles on a single tank of fuel. A 360-horsepower 5.7L Hemi V8 engine is also available on all trims but Laredo. Meanwhile the SRT comes with a 6.4L V8 that makes 465 horsepower. All but the SRT can be outfitted in either 2- or 4-wheel drive, while the SRT utilizes Quadratrac on-demand all-wheel drive.

Independent front and multi-link rear suspension systems and a unit-body structure have made the Grand Cherokee's frame very rigid. Jeep's Quadra-Lift air suspension, capable of lifting the vehicle 4.5 inches for more off-road ground clearance and Selec-Terrain traction control systems are available on 4-wheel-drive trims only.

Standard safety equipment across the lineup includes 4-wheel antilock disc brakes, active head restraints, a full array of airbags, including full-length side-curtain and seat-mounted side thorax air bags, electronic stability control, electronic roll mitigation, hill-start assist, auto-on headlights, trailer-sway control and tire pressure monitoring system. Adaptive cruise control is also available, along with front collision alert and front park assist.

Standard equipment on the base Laredo includes keyless entry, 17-inch aluminum wheels, dual-zone air conditioning, a leather-wrapped steering wheel with audio controls, an anti-theft system, MP3 player and an auxiliary power outlet.

The Limited trim adds upgraded 18-inch aluminum wheels, a leather interior with power-adjustable heated seats and memory. The panoramic sunroof is an upgrade, as is a premium sound system with hard disk storage and satellite radio. Safety and convenience are enhanced with a rear parking aid, integrated turn signal mirrors, rain-sensing wipers and HID headlights. Comfort enhancements include automatic climate control, proximity entry and heated rear seats.

Trailhawk models come with Jeep's Quadra-Drive II 4x4 system, which uses an electronic limited-slip differential in the rear and Quadra-Lift air suspension to improve off-road performance. These refinements add improved articulation and additional travel to the already capable Grand Cherokee. The Trailhawk also gets a unique black interior with suede performance seats, and a gunmetal finish for the interior trim. Outside, Trailhawk models get 18-inch wheels, red tow hooks, Goodyear Adventure off-road tires with Kevlar reinforcement and red Trailhawk badges.

The Overland gets 20-inch aluminum wheels, Napa leather upholstery with heated and ventilated front seats and a heated wood/leather steering wheel. It also gains a remote trunk release and a power liftgate.

The Summit includes adaptive cruise control, a blind-spot/rear cross-path detection system, front collision warning and exterior trim enhancements.

Options available across the lineup include a rear DVD entertainment system, a full-size spare, an array of aluminum wheel options and two different levels of towing equipment. A collision preventing blind-spot/rear cross-path detection system is available, as is an adaptive cruise control with Forward Collision Warning.

The 4-wheel-drive models are all seriously capable, but can be outfitted to a greater degree depending on the customer's interest. Off-road packages that include skid plates, hill descent control and a high-performance Quadra-Drive II 4WD system are available.

The Grand Cherokee SRT is a different beast. Intended for on-road performance, it utilizes an on-demand four-wheel drive system, a 465-horsepower 6.4L V8 engine and an 8-speed automatic transmission. Underneath, there's an electronic limited-slip differential, active damping suspension and performance-tuned steering. Big 20-inch aluminum wheels, special body-color trim, HID headlamps, fog lamps and rain-sensing wipers are standard as well. Inside, the SRT comes with heated and ventilated power-adjustable leather seats, a heated steering wheel and keyless proximity entry.

The biggest news for 2017 is the addition of the Trailhawk trim. Focused on true off-road performance, Trailhawk-trimmed Grand Cherokees include special differentials, additional ground clearance and unique interior and exterior styling cues. Other refinements for 2017 include a new appearance package for summit models, new leather interior packages, a new front fascia for SRT models and a rearview camera that now comes standard across the entire range.

The Jeep Grand Cherokee has proven itself the premiere luxury SUV for 20 years. The latest Grand Cherokee builds on that tradition by offering civilized highway driving as well as the equipment to make a credible show off-road. The base Laredo 4x2 starts at just under $30,000 and comes very well equipped. Meanwhile, the top-of-the-line SRT models' all-wheel-drive on-road performance rivals that of the Porsche Cayenne Turbo, but for half the price.
