Safety

The X6’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.

A passive infrared night vision system optional on the X6 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 X6 offers an optional Surround View Cameras 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.

The X6’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Grand Cherokee doesn’t offer a driver alert monitor.

Both the X6 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras and available all wheel drive.

Warranty

The X6 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Grand Cherokee’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The X6’s corrosion warranty is 7 years longer than the Grand Cherokee’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X6 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Jeep doesn’t pay scheduled maintenance for the Grand Cherokee.

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the X6 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 X6 has a 210-amp alternator. The Grand Cherokee’s standard 160-amp alternator isn’t as powerful.

J.D. Power and Associates rated the X6 first among midsize premium SUVs in their 2018 Initial Quality Study. The Grand Cherokee isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Jeep vehicles. J.D. Power ranks BMW 11th in initial quality, above the industry average. With 9 more problems per 100 vehicles, Jeep is ranked 17th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Jeep vehicles. J.D. Power ranks BMW 8th in reliability, above the industry average. With 61 more problems per 100 vehicles, Jeep is ranked 28th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Jeep vehicles. Consumer Reports ranks BMW 14 places higher in reliability than Jeep.

Engine

The X6 s/xDrive35i’s standard 3.0 turbo 6 cyl. produces 7 more horsepower (302 vs. 295) and 35 lbs.-ft. more torque (295 vs. 260) than the Grand Cherokee’s standard 3.6 DOHC V6. The X6 xDrive50i’s standard 4.4 turbo V8 produces 85 more horsepower (445 vs. 360) and 89 lbs.-ft. more torque (479 vs. 390) than the Grand Cherokee’s optional 5.7 V8.

As tested in Motor Trend the X6 s/xDrive35i is faster than the Jeep Grand Cherokee:

Fuel Economy and Range

On the EPA test cycle the X6 xDrive35i gets better fuel mileage than the Grand Cherokee 4x4 V8 (18 city/24 hwy vs. 14 city/22 hwy).

Regenerative brakes improve the X6’s fuel efficiency by converting inertia back into energy instead of wasting it. The Grand Cherokee doesn’t offer a regenerative braking system.

Regardless of its engine, the X6’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Jeep only offers an automatic engine start/stop system on the Grand Cherokee V6.

Transmission

The X6’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Grand Cherokee doesn’t offer launch control.

Brakes and Stopping

For better stopping power the X6’s front brake rotors are larger than those on the Grand Cherokee:

Tires and Wheels

For better traction, the X6 has larger standard tires than the Grand Cherokee (255/50R19 vs. 245/70R17). The X6’s optional tires are larger than the largest tires available on the Grand Cherokee (F:275/40R20 & R:315/35R20 vs. 265/50R20).

The X6’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Grand Cherokee Laredo’s standard 70 series tires. The X6 xDrive50i’s optional 275/35R21 front and 315/30R21 rear tires have a lower 35 series front and 30 series rear profile than the Grand Cherokee’s optional 50 series tires.

For better ride, handling and brake cooling the X6 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Grand Cherokee Laredo. The X6 xDrive50i’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Grand Cherokee.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X6 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Grand Cherokee doesn’t offer run-flat tires.

Suspension and Handling

The X6 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Jeep doesn’t offer an active suspension on the Grand Cherokee.

The X6 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 X6 is .7 inches wider in the front and 3.1 inches wider in the rear than on the Grand Cherokee.

The X6 xDrive35i handles at .88 G’s, while the Grand Cherokee Limited 4x4 pulls only .73 G’s of cornering force in a Motor Trend skidpad test.

The X6 xDrive35i executes Motor Trend’s “Figure Eight” maneuver 2.7 seconds quicker than the Grand Cherokee Summit 4x4 (26.1 seconds @ .71 average G’s vs. 28.8 seconds @ .59 average G’s).

Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the X6’s available 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 BMW service is better than Jeep. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 73% lower rating, Jeep is ranked 28th.

Ergonomics

Unlike the driver-only memory system in the Grand Cherokee Limited/Trailhawk/Overland/Summit, the X6 offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The X6 offers an optional heads-up display that projects speed and other key instrumentation 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 X6’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Grand Cherokee’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the X6 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the Grand Cherokee can only operate the windows from inside the vehicle, with the ignition on.

The X6’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Grand Cherokee’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the X6 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Grand Cherokee doesn’t offer heated windshield washer nozzles.

To help drivers avoid possible obstacles, the X6 has standard cornering lights to illuminate around corners when the turn signals are activated. The Grand Cherokee doesn’t offer cornering lights. The X6 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Economic Advantages

Insurance will cost less for the X6 owner. The Car Book by Jack Gillis rates the X6 with a number “1” insurance rate while the Grand Cherokee is rated higher at a number “8” rate.

According to The Car Book by Jack Gillis, the X6 is less expensive to operate than the Grand Cherokee because typical repairs cost less on the X6 than the Grand Cherokee, including $114 less for a timing belt/chain.
