Compare the2024 BMW X6VS 2023 Aston Martin DBX

The X6’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The DBX doesn’t offer pre-crash pretensioners.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the X6 are reminded to check the back seat if they opened the rear door before starting out. The DBX doesn’t offer a back seat reminder.

The X6 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The DBX doesn’t offer a whiplash protection system.

The X6 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The DBX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The X6 offers an optional Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The DBX doesn’t offer automatic braking for stationary objects directly to the rear.

The X6’s 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 DBX doesn’t offer a driver alert monitor.

The X6 has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The DBX doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the X6 and the DBX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

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 DBX’s 3-year basic warranty expires 1 year sooner.

The X6’s corrosion warranty is 2 years longer than the DBX’s (12 vs. 10 years).

BMW pays for scheduled maintenance on the X6 for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Aston Martin doesn’t pay scheduled maintenance for the DBX.

There are over 10 times as many BMW dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the X6’s warranty.

The X6 M60i xDrive’s standard 4.4 turbo V8 hybrid produces 37 lbs.-ft. more torque (553 vs. 516) than the DBX’s standard 4.0 turbo V8.

On the EPA test cycle the X6 gets better mileage than the DBX:

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

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available 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 DBX doesn’t offer run-flat tires.

For better handling and stability, the track (width between the wheels) on the X6 is 1.4 inches wider in the rear than on the DBX.

The X6’s front to rear weight distribution is more even (50.6% to 49.4%) than the DBX’s (52.7% to 47.3%). This gives the X6 more stable handling and braking.

The X6 is 3.4 inches shorter than the DBX, making the X6 easier to handle, maneuver and park in tight spaces.

The front grille of the X6 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The DBX doesn’t offer active grille shutters.

The X6 has 1.6 inches more front shoulder room and 3.2 inches more rear shoulder room than the DBX.

The X6 has a much larger cargo volume with its rear seat up than the DBX with its rear seat up (27.4 vs. 22.5 cubic feet). The X6 has a much larger cargo volume with its rear seat folded than the DBX with its rear seat folded (59.6 vs. 54 cubic feet).

A Condition-Based Service Display is standard on the X6 to save the owner time and money by calculating maintenance intervals for oil changes, spark plug replacement, and vehicle inspections, based on actual driving conditions. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Aston Martin doesn’t offer a maintenance reminder on the DBX.

The X6 offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The DBX doesn’t offer a remote starting system.

The X6 offers an optional heads-up display that projects speed, tachometer, warning, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The DBX doesn’t offer a heads-up display.

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

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X6 has standard extendable sun visors. The DBX doesn’t offer extendable visors.

Manual rear side window sunshades are available in the X6 to help block heat and glare for the rear passengers. The DBX doesn’t offer rear side window sunshades.

The X6 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the DBX.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X6 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the DBX.

The X6’s Parking Assistant Plus can parallel park or back into a parking spot by itself, with the driver only controlling the transmission and speed with the brake pedal. With its available fully controlled system, the driver just activates it and it parks autonomously, starting, stopping and changing direction automatically. Optional Remote Parking will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The DBX’s automatic parking system requires operating the brakes and transmission to safely park and it doesn’t offer remote control parking.

J.D. Power and Associates rated the X6 second among upper midsize premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The DBX isn’t in the top three.

The BMW X6 outsold the Aston Martin DBX by over 16 to one during 2022.
