Compare the2024 Aston Martin DBXVS 2024 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.

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 Grand Cherokee have rear cross-traffic warning, but the DBX has Rear Cross Traffic Warning (automatically applies the brakes) to better prevent a collision when backing near traffic. The Grand Cherokee’s Rear Cross Path Detection doesn’t automatically brake.

Both the DBX and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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).

The DBX’s standard 4.0 turbo V8 produces 249 more horsepower (542 vs. 293) and 259 lbs.-ft. more torque (516 vs. 257) than the Grand Cherokee’s standard 3.6 DOHC V6. The DBX’s 4.0 turbo V8 produces 167 more horsepower (542 vs. 375) and 46 lbs.-ft. more torque (516 vs. 470) than the Grand Cherokee 4xe’s standard 2.0 turbo 4-cylinder hybrid. The DBX707’s standard 4.0 turbo V8 produces 322 more horsepower (697 vs. 375) and 193 lbs.-ft. more torque (663 vs. 470) than the Grand Cherokee 4xe’s standard 2.0 turbo 4-cylinder hybrid.

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

An engine control system that can shut down some of the engine’s cylinders helps improve the DBX’s fuel efficiency. The Grand Cherokee doesn’t offer a system that can shut down part of the engine.

Both the DBX and the Grand Cherokee have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All DBXs have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. A disable switch for start/stop is only offered on the Grand Cherokee V6.

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

The DBX has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Grand Cherokee. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

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 Reserve’s 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 on the Grand Cherokee Summit Reserve.

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 DBX707 handles at .97 G’s, while the Grand Cherokee 4x4 pulls only .79 G’s of cornering force in a Car and Driver 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.

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’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.
