Compare the2023 Aston Martin DBXVS 2023 Jeep Grand Cherokee

For enhanced safety, the front and rear seat shoulder belts of the Aston Martin DBX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Jeep Grand Cherokee doesn’t offer pretensioners for its rear seat belts.

The Aston Martin DBX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Grand Cherokee doesn’t offer a front passenger side knee airbag.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the DBX. But it costs extra on the Grand Cherokee.

Both the DBX and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The DBX comes with a full 3-year/unlimited-mile basic warranty, which covers the entire truck and includes free 24-hour roadside assistance. The Grand Cherokee’s 3-year/36,000-mile basic warranty expires sooner.

The DBX’s corrosion warranty is 5 years longer than the Grand Cherokee’s (10 vs. 5 years).

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

The DBX has more powerful engines than the Grand Cherokee:

As tested in Motor Trend the Aston Martin DBX 4.0 is faster than the Jeep Grand Cherokee V6:

Regardless of its engine, the DBX’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 V6/4xe.

The DBX has 3.5 gallons more fuel capacity than the Grand Cherokee 4xe Hybrid’s standard fuel tank (22.5 vs. 19 gallons), for longer range between fill-ups.

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

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

The DBX 707 has standard heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Grand Cherokee doesn’t offer ceramic brake rotors.

The DBX stops much shorter than the Grand Cherokee:

For better traction, the DBX has larger tires than the Grand Cherokee (F:285/40R22 & R:325/35R22 vs. 245/70R17). The DBX’s tires are larger than the largest tires available on the Grand Cherokee (F:285/40R22 & R:325/35R22 vs. 275/45R21).

The DBX’s standard 285/40R22 front and 325/35R22 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Grand Cherokee Laredo’s standard 70 series tires. The DBX’s optional 285/35R23 front and 325/30R23 rear tires have a lower 35 series front and 30 series rear profile than the Grand Cherokee Summit’s optional 45 series tires.

For better ride, handling and brake cooling the DBX has standard 22-inch wheels. Smaller 17-inch wheels are standard on the Grand Cherokee Laredo. The DBX’s optional 23-inch wheels are larger than the 21-inch wheels optional on the Grand Cherokee Summit.

The front and rear suspension of the DBX uses air springs for a smoother, controlled ride than the Grand Cherokee, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The DBX offers an available 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.

For a smoother ride and more stable handling, the DBX’s wheelbase is 3.8 inches longer than on the Grand Cherokee (120.5 inches vs. 116.7 inches).

For better handling and stability, the track (width between the wheels) on the DBX is 1.5 inches wider in the front and .1 inches wider in the rear than on the Grand Cherokee.

The DBX handles at .95 G’s, while the Grand Cherokee Overland 4x4 pulls only .60 G’s of cornering force in a Motor Trend skidpad test.

The DBX executes Motor Trend’s “Figure Eight” maneuver 3.7 seconds quicker than the Grand Cherokee Limited 4x4 (24.4 seconds @ .79 average G’s vs. 28.1 seconds @ .58 average G’s).

For greater off-road capability the DBX has a greater minimum ground clearance than the Grand Cherokee (9.3 vs. 8.4 inches), allowing the DBX to travel over rougher terrain without being stopped or damaged.

The DBX has 1 inch more front headroom, .4 inches more front legroom, .6 inches more rear headroom and 2.7 inches more rear legroom than the Grand Cherokee.

Flexibility is maximized at the game, campground or a drive-in theatre in the DBX when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The Grand Cherokee doesn’t offer tailgating seats.

A low lift-over cargo hatch design makes loading and unloading the DBX easier. The DBX’s cargo hatch lift-over height is 31.9 inches, while the Grand Cherokee’s liftover is 33 inches.

Pressing a button automatically lowers the DBX’s rear seats, to make changing between passengers and cargo easier. The Grand Cherokee doesn’t offer automatic folding seats.

The DBX’s standard towing capacity is much higher than the Grand Cherokee’s (5940 vs. 3500 pounds).

The DBX’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 standard rear power window switches have to be held the entire time to open or close them fully. The Grand Cherokee Overland/Summit’s .

If the windows are left open on the DBX the driver can close them all 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 DBX has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The Grand Cherokee doesn’t offer a locking fuel/charge port door.

The DBX’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 intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To better shield the driver and front passenger’s vision, the DBX has standard dual-element sun visors that can block glare from two directions simultaneously. The Grand Cherokee doesn’t offer secondary sun visors.
