Compare the2024 Aston Martin DBXVS 2023 Porsche Cayenne

The DBX’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 Cayenne.

The DBX has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Cayenne’s blind spot costs extra.

To help make backing out of a parking space safer, the DBX’s standard Rear Cross Traffic Warning uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The Cayenne doesn’t offer a rear cross-path warning system.

Both the DBX and the Cayenne have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights and rearview cameras.

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 Cayenne’s 50,000-mile basic warranty expires sooner.

The DBX has more powerful engines than the Cayenne:

As tested in Car and Driver the Aston Martin DBX 4.0 is faster than the Porsche Cayenne turbo V6:

On the EPA test cycle the DBX gets better mileage than the Cayenne running its gasoline engine:

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

The DBX has 2.7 gallons more fuel capacity than the Cayenne E-Hybrid’s standard fuel tank (22.5 vs. 19.8 gallons), for longer range between fill-ups.

The DBX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Cayenne doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Aston Martin DBX higher (5 out of 10) than the Porsche Cayenne (3 to 5). This means the DBX produces up to 16.5 pounds less smog-producing pollutants than the Cayenne every 15,000 miles.

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 Cayenne.

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

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The DBX has a standard Emergency Brake Assist to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Cayenne doesn’t offer a brake assist feature.

The DBX stops shorter than the Cayenne:

For better traction, the DBX has larger tires than the Cayenne (F:285/40R22 & R:325/35R22 vs. F:255/55R19 & R:275/50R19).

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 Cayenne’s standard 55 series front and 50 series rear tires.

For better ride, handling and brake cooling the DBX has standard 22-inch wheels. Smaller 19-inch wheels are standard on the Cayenne. The DBX’s optional 23-inch wheels are larger than the 22-inch wheels optional on the Cayenne.

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

For a smoother ride and more stable handling, the DBX’s wheelbase is 6.5 inches longer than on the Cayenne (120.5 inches vs. 114 inches).

The DBX707 handles at .97 G’s, while the Cayenne pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

The DBX executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the Cayenne E-Hybrid (24.4 seconds @ .79 average G’s vs. 25.4 seconds @ .78 average G’s).

For greater off-road capability the DBX has a 1.1 inches greater minimum ground clearance than the Cayenne (9.3 vs. 8.2 inches), allowing the DBX to travel over rougher terrain without being stopped or damaged.

The DBX has 1.9 inches more front headroom, .6 inches more front legroom, 1 inch more rear headroom and .6 inches more rear legroom than the Cayenne.

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 Cayenne doesn’t offer tailgating seats.

The DBX’s cargo area is larger than the Cayenne’s in almost every dimension:

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

The DBX’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the Cayenne.

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 Cayenne can only operate the windows from inside the vehicle, with the ignition on.

The DBX’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Cayenne’s cruise control switches are unlit, making them difficult to find at night and operate safely.
