Safety
Warranty
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.
Engine
The DBX’s 4.0 turbo V8 produces 349 more horsepower (697 vs. 348) and 296 lbs.-ft. more torque (664 vs. 368) than the Cayenne’s standard 3.0 turbo V6. The DBX’s 4.0 turbo V8 produces 234 more horsepower (697 vs. 463) and 185 lbs.-ft. more torque (664 vs. 479) than the Cayenne E-Hybrid’s standard 3.0 turbo V6 hybrid. The DBX’s 4.0 turbo V8 produces 229 more horsepower (697 vs. 468) and 222 lbs.-ft. more torque (664 vs. 442) than the Cayenne S’ standard 4.0 turbo V8.

Fuel Economy and Range
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 4 gallons more fuel capacity than the Cayenne S E-Hybrid/Turbo E-Hybrid’s standard fuel tank (22.5 vs. 18.5 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.
Transmission
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.
Brakes and Stopping
For better stopping power the DBX’s standard brake rotors are larger than those on the Cayenne:
|
DBX |
Cayenne |
Front Rotors |
16.5 inches |
14.2 inches |
Rear Rotors |
15.4 inches |
13 inches |
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.
Tires and Wheels
For better traction, the DBX has larger tires than the Cayenne (F:285/40R22 & R:325/35R22 vs. F:255/55R20 & R:295/45R20).
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 45 series rear 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 Cayenne’s optional 40 series front and 35 series rear tires.
For better ride, handling and brake cooling the DBX has standard 22-inch wheels. Smaller 20-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.
Suspension and Handling
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 DBX’s front to rear weight distribution is more even (52.7% to 47.3%) than the Cayenne’s (56% to 44%). This gives the DBX more stable handling and braking.
The DBX handles at .95 G’s, while the Cayenne S pulls only .90 G’s of cornering force in a Motor Trend skidpad test.
The DBX executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the Cayenne S (24.4 seconds @ .79 average G’s vs. 25.6 seconds @ .75 average G’s).
For greater off-road capability the DBX has a 1.2 inches greater minimum ground clearance than the Cayenne E-Hybrid (9.3 vs. 8.1 inches), allowing the DBX to travel over rougher terrain without being stopped or damaged.
Passenger Space
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.
Cargo Capacity
The DBX’s cargo area is larger than the Cayenne’s in almost every dimension:
|
DBX |
Cayenne |
Length to seat (2nd/1st) |
40.2”/70.1” |
39.6”/74.9” |
Max Width |
45.7” |
42” |
Min Width |
45” |
42” |
Height |
27.3” |
30.4” |
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.
Ergonomics
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.
