The XT6 Premium Luxury/Sport’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Grand Cherokee doesn’t offer pre-crash pretensioners.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT6 are reminded to check the back seat if they opened the rear door before starting out. The Grand Cherokee doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The XT6 Premium Luxury/Sport offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Grand Cherokee doesn’t offer backup collision prevention brakes.

A passive infrared night vision system optional on the XT6 Premium Luxury/Sport helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Grand Cherokee doesn’t offer a night vision system.

The XT6’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Grand Cherokee.

The XT6 Premium Luxury/Sport offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Grand Cherokee only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the XT6 and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available all wheel drive.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Cadillac XT6 is safer than the Jeep Grand Cherokee:

	XT6	Grand Cherokee

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH, results indicate that the Cadillac XT6 is safer than the Jeep Grand Cherokee:

	XT6	Grand Cherokee
	Front Seat
STARS	5 Stars	5 Stars
Chest Movement	.7 inches	.8 inches
Abdominal Force	117 lbs.	126 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
Hip Force	249 lbs.	689 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the XT6 is .5% to 4.9% less likely to roll over than the Grand Cherokee.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the XT6 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 80 vehicles tested by the IIHS. The Grand Cherokee is not even a standard “Top Safety Pick.”

Warranty

The XT6 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck. The Grand Cherokee’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Cadillac’s powertrain warranty covers the XT6 1 year and 10,000 miles longer than Jeep covers the Grand Cherokee. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Grand Cherokee ends after only 5 years or 60,000 miles.

The XT6’s corrosion warranty is 1 year longer than the Grand Cherokee’s (6 vs. 5 years).

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the XT6 have an overhead cam design, rather than the old pushrod design of the 5.7 V8 in the Grand Cherokee.

To reliably power the ignition and other systems and to recharge the battery, the XT6 has a standard 220-amp alternator. The Grand Cherokee’s standard 160-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than Jeep vehicles. J.D. Power ranks Cadillac above average in long-term dependability. With 24 more problems per 100 vehicles in the first three years of ownership, Jeep is rated below average.

Engine

The XT6 Premium Luxury/Sport’s standard 3.6 DOHC V6 produces 15 more horsepower (310 vs. 295) and 11 lbs.-ft. more torque (271 vs. 260) than the Grand Cherokee’s standard 3.6 DOHC V6.

As tested in Motor Trend the XT6 Premium Luxury/Sport 3.6 DOHC V6 is faster than the Jeep Grand Cherokee V6:

	XT6	Grand Cherokee
Zero to 60 MPH	6.8 sec	7.7 sec
Quarter Mile	15.2 sec	15.8 sec
Speed in 1/4 Mile	93.1 MPH	88.4 MPH

Fuel Economy and Range

On the EPA test cycle the XT6 gets better mileage than the Grand Cherokee:

			MPG
XT6
	FWD	2.0 turbo 4-cyl.	21 city/27 hwy
	AWD	2.0 turbo 4-cyl.	21 city/26 hwy
		3.6 DOHC V6	18 city/25 hwy
Grand Cherokee
	RWD	3.6 DOHC V6	19 city/26 hwy
	AWD	3.6 DOHC V6	18 city/25 hwy
		5.7 OHV V8	14 city/22 hwy

Regardless of its engine, the XT6’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. Jeep only offers an automatic engine start/stop system on the Grand Cherokee V6.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT6 higher (6 to 7 out of 10) than the Jeep Grand Cherokee (3 to 7). This means the XT6 produces up to 24.5 pounds less smog-producing pollutants than the Grand Cherokee every 15,000 miles.

The EPA certifies the Cadillac XT6 as an “Ultra Low Emissions Vehicle” (ULEV). The Jeep Grand Cherokee is only certified to “Low Emissions Vehicle” (LEV) standards.

Transmission

A nine-speed automatic is standard on the Cadillac XT6, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Grand Cherokee.

Tires and Wheels

The XT6 Premium Luxury/Sport’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Grand Cherokee’s optional 50 series tires.

For better ride, handling and brake cooling the XT6 Premium Luxury/Sport offers optional 21-inch wheels. The Grand Cherokee’s largest wheels are only 20-inches.

The Cadillac XT6’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Jeep Grand Cherokee only has 5 wheel lugs per wheel.

The XT6 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Grand Cherokee doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The XT6 offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Grand Cherokee’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the track (width between the wheels) on the XT6 is 2.5 inches wider in the front and 2.1 inches wider in the rear than on the Grand Cherokee.

The XT6 Sport AWD handles at .88 G’s, while the Grand Cherokee Summit 4x4 pulls only .72 G’s of cornering force in a Car and Driver skidpad test.

The XT6 Sport AWD executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the Grand Cherokee Summit 4x4 (27.2 seconds @ .67 average G’s vs. 28.8 seconds @ .59 average G’s).

Chassis

The front grille of the XT6 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Grand Cherokee doesn’t offer active grille shutters.

Passenger Space

The XT6 has standard seating for 7 passengers; the Grand Cherokee can only carry 5.

The XT6 has .9 inches more front legroom and .5 inches more rear legroom than the Grand Cherokee.

The front step up height for the XT6 is 2 inches lower than the Grand Cherokee (18.5” vs. 20.5”). The XT6’s rear step up height is 1.8 inches lower than the Grand Cherokee’s (19” vs. 20.8”).

Cargo Capacity

The XT6’s cargo area provides more volume than the Grand Cherokee.

	XT6	Grand Cherokee
Third Seat Folded	43.1 cubic feet	n/a
Third Seat Removed	n/a	36.3 cubic feet
Second Seat Folded	78.7 cubic feet	68.3 cubic feet

The XT6’s cargo area is larger than the Grand Cherokee’s in almost every dimension:

	XT6	Grand Cherokee
Length to seat (3rd/2nd/1st)	15.5”/48”/80.2”	n.a./38.5”/74.2”
Max Width	50”	47.6”
Min Width	43”	41.7”
Height	32.5”	33.5”

Pressing a switch automatically lowers the XT6’s second and third row seats, to make changing between passengers and cargo easier. The Grand Cherokee doesn’t offer automatic folding second row seats.

To make loading groceries and cargo easier when your hands are full, the XT6 Premium Luxury/Sport’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Grand Cherokee doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Jeep. J.D. Power ranks Cadillac second in service department satisfaction. With a 46% lower rating, Jeep is ranked 26th.

Ergonomics

The XT6 Premium Luxury/Sport offers an optional heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Grand Cherokee doesn’t offer a heads-up display.

The XT6’s power parking brake sets with one touch and releases with one touch or automatically. The Grand Cherokee’s parking brake has to be released manually.

The XT6’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Grand Cherokee’s rear power window switches have to be held the entire time to open them fully.

On a hot day the XT6’s driver can lower all the windows from a distance using the keyless remote. The driver of the Grand Cherokee can only operate the windows from inside the vehicle, with the ignition on.

To help drivers avoid possible obstacles, the XT6 has standard cornering lights to illuminate around corners when the turn signals are activated. The Grand Cherokee doesn’t offer cornering lights.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac XT6 Premium Luxury/Sport has a standard wireless phone charging system (Qi) in the center console. The Grand Cherokee doesn’t offer wireless personal charging.

The XT6 Premium Luxury/Sport’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Grand Cherokee’s automatic parking system requires operating the brakes and transmission to safely park.

Economic Advantages

According to The Car Book by Jack Gillis, the XT6 is less expensive to operate than the Grand Cherokee because typical repairs cost less on the XT6 than the Grand Cherokee, including $21 less for front brake pads, $76 less for a starter, $98 less for a fuel pump and $76 less for front struts.
