Compare the2025 BMW X6VS 2024 Bentley Bentayga

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 Bentayga doesn’t offer a back seat reminder.

The BMW X6 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 Bentayga doesn’t offer knee airbags.

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 Bentayga 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 Bentayga doesn’t offer automatic braking for stationary objects directly to the rear.

The X6’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 Bentayga.

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 Bentayga doesn’t offer a driver alert monitor.

Both the X6 and the Bentayga have standard driver and passenger frontal airbags, front side-impact 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, 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 Bentayga’s 3-year basic warranty expires 1 year sooner.

The X6’s corrosion warranty is 9 years longer than the Bentayga’s (12 vs. 3 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. Bentley doesn’t pay scheduled maintenance for the Bentayga.

There are over 7 times as many BMW dealers as there are Bentley 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 67 more horsepower (523 vs. 456) and 37 lbs.-ft. more torque (553 vs. 516) than the Bentayga Hybrid’s standard 3.0 turbo V6 hybrid.

On the EPA test cycle the X6 gets better mileage than the Bentayga running its gasoline engine:

The X6 has 2.1 gallons more fuel capacity than the Bentayga Hybrid’s standard fuel tank (21.9 vs. 19.8 gallons), for longer range between fill-ups.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X6 higher (5 to 7 out of 10) than the Bentley Bentayga (3). This means the X6 produces up to 24.5 pounds less smog-producing pollutants than the Bentayga every 15,000 miles.

The EPA certifies the BMW X6 as an “Ultra Low Emissions Vehicle” (ULEV). The Bentley Bentayga is only certified to “Low Emissions Vehicle” (LEV) standards.

The X6’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Bentayga doesn’t offer launch control.

The X6’s optional 275/35R22 front and 315/30R22 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the Bentayga’s optional 40 series tires.

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 Bentayga doesn’t offer run-flat tires.

The BMW X6 may be more efficient, handle and accelerate better because it weighs about 300 to 550 pounds less than the Bentley Bentayga.

The X6 is 6.8 inches shorter than the Bentayga, 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 Bentayga doesn’t offer active grille shutters.

The X6 has a much larger cargo volume than the Bentayga with its rear seat up (27.4 vs. 17.1 cubic feet).

The X6’s standard rear seats fold to accommodate long and bulky cargo. The Bentayga w/Four Seat Comfort Specification doesn’t offer folding rear seats, only a ski pass-through.

If the windows are left open on the X6 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Bentayga can only operate the windows from inside the vehicle, with the ignition on.

The X6’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 Bentayga’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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 Bentayga’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 Bentayga isn’t in the top three.

The BMW X6 outsold the Bentley Bentayga by over five to one during 2023.
